As shown in figure 4, the batteries 4 are flat, rectangular objects block form. The batteries 4 are stacked on the battery frame 11 in a variety of groups A-E battery. Some of the batteries 4 are stacked vertically in each of the left and right partitioned rectangular regions 11F and 11F front of the battery frame 11. Also some of the batteries 4 are arranged in the transverse direction in a partitioned rectangular region 11R rear part of the battery frame 11 how shown in figure 1, vertically stacked batteries 4, is placed in each of the front rectangular regions partitioned 11F and 11F are divided into four groups A, B, C and D batteries, placed next in the longitudinal direction of the vehicle 1. Among them, each of the front groups A and B batteries includes a set of four batteries 4. Also, each of the rear groups C and D batteries includes a set of two batteries 4. Thus, there is a difference in height is set between the front groups A and B batteries and rear groups C and D batteries. Also between the left and right partitioned rectangular regions 11F and 11F each pair of corresponding groups A, B, C and D batteries has the same number of stacked battery 4, so that the left and right of the battery groups are symmetrical to each other. Meanwhile, one group E batteries, arranged in the transverse direction of the vehicle 1, is installed in the rear of the partitioned rectangular region 11R battery frame 11. The front group A and B batteries have a height h1. The rear group C and D batteries have a height h2. One group E battery has a height h3. Thus, in this embodiment, the heights h1, h2 and h3 have a spatial correlation of h3>h1>h2.

The battery cover 12 closes all groups of the A-E battery, as shown in figures 1 and 3. The battery cover 12 removable manner is attached to the battery frame 11. The top plate 12u battery cover 12 is configured so that, in General, to repeat the contour of the upper surfaces of the groups A-E battery. Plate 12u battery cover 12 is also configured to be in close proximity to the upper surfaces. More specifically, the top plate 12u battery cover 12 includes a first section 121 of the cover, the second section 122 of the cover and the third section 123 of the cover. The first section 121 of the cover closes the first group A and B batteries. The second section 122 of the cover closes the second group C and D batteries. The third section 123 of the cover closes the third group E batteries. The first through third sections 121, 122 and 123 caps have a stepped shape. Each of the first and third sections 121, 122 and 123 of the cover has a height corresponding to the height h1-h3 of groups A-E battery, respectively. In this embodiment, since the height h1-h3 are the spatial correlation of h2<h1<h3. The height h2 of the second section 122 of the cover is the smallest. The height h3 of the third section 123 of the cover is the greatest. The height h1 of the first section 121 of the cover is between the heights h2 and h3 of the second and third sections 122 and 123 of the cover.

As shown in figure 4, in the battery unit 100 such to the components as wiring 41, box 42 switches and junction box 43 are placed on the longitudinal element 122c between the left and right partitioned rectangular regions 11F and 11F. The wiring 41 is located between the batteries 4. Various electrical components (i.e., the electric motor 5, a charger 7, an inverter 8, and so on) are placed in the front compartment 6 and is electrically connected with the wiring 41. As shown in figure 3, hole 12h is formed in the second area 122 of the battery cover 12 at the position corresponding box 42 switches. Working part 42a of the box 42 switches is serving up through the hole 12h, so that it can be engaged from the opening and closing of the window (not shown)provided in the floor panel 3.

It is preferable to cool the battery pack 110, if necessary, because the 4 batteries generate heat during use. In this embodiment, the bottom portion of the battery pack 100 is open towards the road surface and, thus, can be cooled by the air flow when the vehicle is moving. In this embodiment, as shown in figure 1, the passage 30 for the flow of air is formed between the bottom surface 3a of the bar 3 floor (i.e., the top surface of the deep part 3S, formed the Oh panel 3 floor to accommodate the battery pack 100 and the upper surface 12s of the battery pack 100, to allow air flow As (see figure 1 and 3), created by the movement of the vehicle 1, to pass from front to back. Thus, the upper portion of the battery pack 100 is cooled by the air.

In this embodiment, the front water or cooling jacket 20F is used to further cool the upper part of the battery pack 100, and the rear or water cooling jacket 20R is used to cool the rear portion of the battery pack 100. The front cooling jacket 20F is mounted on the upper surface 12s of the battery pack 100. Thus, the front cooling jacket 20F allows the upper part of the battery pack 100 to be cooled effectively, even when it is difficult to obtain the effect of cooling by using air flow. The cooling liquid flowing inside the front cooling jacket 20F, serves to cool the upper part (i.e. the top plate 12u, serving as the upper wall) of the battery pack 100. The front cooling jacket 20F is a block liquid cooling. As shown in figure 1, the front cooling jacket 20F is placed facing to the passage 30 to the air stream. In this embodiment, as shown in figure 3, the front cooling jacket 20F is placed in the transverse middle part of the first portion 11 of the cover, which corresponds to the front section of the battery cover 12.

As shown in Fig.6, the front cooling jacket 20F, as a rule, formed similarly flat, rectangular box. The front cooling jacket 20F includes an inlet opening 21, the outlet 22, the main unit 23 and the many channels 24 for coolant. Main unit 23 includes a channel 24 for coolant. The channels 24 for coolant are placed parallel to each other and configured to be duplicated (to bend) back and forth in a zigzag manner between the inlet 21 and outlet 22. 6 shows the inside of the front cooling jacket 20F with the removed cover plate (not shown). The covering plate is attached airtight manner by means of bolts installed in many threaded holes 25 formed in the area of the rim surrounding the channels 24 for coolant main unit 23. The Assembly is placed between the cover plate and the main unit 23 when the cover plate is installed.

When the coolant flows through the zigzag channel 24 for coolant front cooling jacket 20F in its path from the inlet 21 to the outlet 22, it exchanges heat with running the ESD unit 23. Then the main unit 23 exchanges heat with the top plate 12u battery cover 12, which is the main unit 23. As a result, the coolant allows the upper part of the battery pack 100 is effectively cooled. The front cooling jacket 20F and the rear cooling jacket 20R (explained later), are connected with a heat sink (not shown)provided in the front part of the front cover 6, a pair of pipes 26 for coolant (see Fig.7 and 8), so that the coolant is cooled by the radiator.

As shown in Fig.7, the tunnel 52 in the floor is formed in a transversely middle part of the floor panel 3 and runs essentially in the longitudinal direction of the vehicle 1. The tunnel 52 in the floor is in the upper direction of the vehicle body 1. In this embodiment, at least the upper portion of the passage 30 to the air stream formed by the tunnel 52 in the floor. In this embodiment, the tunnel 52 in the floor narrows slightly in the upward direction. In other words, the upper portion of the tunnel 52 in the floor is narrower than the lower portion of the tunnel 52 in the floor, so that the tunnel 52 in the floor has a trapezoidal cross-sectional shape. Wiring 41, the piping 26 for cooling liquid, a pair of brake tubes 27 and other components are laid cher the C inner space of the tunnel 52 in the floor. In this embodiment, the front cooling jacket 20F is placed inside the tunnel 52 in the floor at the bottom of the tunnel 52 in the floor.

As shown in figure 3 and 8, zheloboobraznogo section 125 is provided in the inclined section 124 between the second section 122 of the cover and the third section 123 of the battery cover 12. In this embodiment, zheloboobraznogo section 125 is formed in the top plate 12u at the position corresponding transversely-average plot slope 124. Zheloboobraznogo section 125 deepened down to have a predefined width and a relatively small depth. Zheloboobraznogo section 125 runs essentially in the longitudinal direction of the vehicle 1. Zheloboobraznogo section 125 generates at least part of the lower section of the passage 30 for air flow. In this embodiment, zheloboobraznogo section 125 is used as a guide for piping 26 for coolant, brake tubes 27 and other components, passes through a tunnel 52 in the floor.

As described above, in this embodiment, the tunnel 52 in the floor, and zheloboobraznogo section 125 are placed in a middle position relative to the transverse direction of the vehicle 1. The tunnel 52 in the floor and zheloboobraznogo section 125 also both oriented to pass in the longitudinal direction of the Tr is Sportage means 1. As a result, the air passing through the tunnel 52 in the floor, runs back relative to the longitudinal direction of the vehicle 1 and runs more smoothly through zheloboobraznogo section 125. In other words, the air stream As sent by the tunnel 52 in the floor and zheloboobraznogo section 125 to flow in the longitudinal direction to the transverse middle part of the vehicle 1. Air flow is additionally allocated As tunnel 52 in the floor and zheloboobraznogo section 125 so as to become the main air flow passage 30 for the flow of air is formed between the floor panel 3 and the battery unit 100.

In this embodiment, the battery cover 12 is made of heat-conductive material (e.g. metal, such as a material based on iron or aluminum alloy). As a result, the cooling effect of the front cooling jacket 20F can be achieved over a wider area, and variation (unevenness) of the cooling effect on the left and right sides of the front cooling jacket 20F, resulting in that the front cooling jacket 20F is in the transversely middle section can be suppressed. The top plate 12u serves as the upper wall of the battery cover 12. The top plate 12u issued or acts up, so that the cross is about average plot is situated in a higher position which also matches the position where the front cooling jacket 20F. With such a convex or protruding form the heat from the battery 4 causes the temperature of the air inside the space S of the battery casing 10 to be higher in higher positions within the space S, i.e. in the upper plot St transversely middle portion of the space S. Thus, cooling the top plate 12u, which is closely adjacent to the upper part of St space S, the front cooling jacket 20F cools the space S and, thus, cools the batteries 4 in an effective manner.

In this embodiment, the flexible thermally conductive sheet element 29 (for example, sheet-like element, which contains an acrylic or other synthetic resin material, which is flexible and thermally conductive) is placed between the front cooling jacket 20F and the top plate 12u. Thermally conductive sheet element 29 is placed so that it is tightly glued to the bottom surface of the front cooling jacket 20F, and to the upper surface 12s of the top plate 12u. As a result, the efficiency with which heat is conducted between the front cooling jacket 20F and the top plate 12u, can be increased. Also the cooling effect of the front cooling jacket 20F can be improved, the village is olcu the gap between the cooling jacket 20F and the top plate 12u decreases, and is more close contact.

The rear surface of the battery pack 100 has a small contact with air flow, the resulting motion of the vehicle 1, and is not completely cooled air flow. Therefore, in this embodiment, the rear cooling jacket 20R is attached to a transversely passing through the rear surface 12r battery cover 12, which corresponds to the rear surface of the battery pack 100, as shown in figures 1 and 3. The cooling liquid flowing inside the cooling jacket 20R, serves for cooling the rear part of the battery unit 100 (i.e., plate 12b on the rear side). The rear cooling jacket 20R is a block liquid cooling. Similarly, the front cooling jacket 20F shown in Fig.6, the rear cooling jacket 20R has a main unit comprising multiple channels for a coolant, which are placed parallel to each other and laid in a zigzag shape between the inlet and the outlet. When the coolant flows through the zigzag channel for coolant his way from the inlet to the outlet, it exchanges heat with the main unit. The main unit then exchanges heat with the side plate 12b of the battery to the ISCI 12, which is the main unit. As a result, the coolant can cool the rear portion of the battery pack 100.

In this embodiment, as explained previously, the tunnel 52 in the floor and zheloboobraznogo section 125 are placed in the transverse middle part of the vehicle 1, so that the air stream As flowing from front to back through the transverse middle portion of the vehicle 1 becomes the primary air flow passage 30 for air flow. As a result, the air stream As it goes to the transverse middle part of the rear cooling jacket 20R.

In this embodiment, the groove 28 is formed in the upper end area of the back of the shirt 20R in a transversely middle position, so that the air flow As passing through the passage 30 to the air flow comes back in the groove 28. As shown in figure 3, the groove 28 forms at least part of the lower extreme rear part of the passage 30 for air flow. Since the rear cooling jacket 20R is cooled by an air stream As flowing through the groove 28, the temperature of the rear cooling jacket 20R can be lowered in a simpler manner than with the configuration in which the groove 28 is not provided.

In this embodiment, as shown in figure 3, the section 123c with a rounded edge is formed on the upper face of the rear is th end of the battery cover 12 in position, the corresponding groove 28. Section 123c with a rounded edge allows air flow As the current above the upper surface 12s of the third section 123 of the cover in the longitudinal direction of the vehicle 1, to flow more smoothly in the groove 28, thereby improving the characteristics of the release back airflow As.

As explained previously, in this embodiment, the front cooling jacket 20F is attached to the upper surface 12s of the battery cover 12, a component of the battery casing 10 of the battery pack 100. The effectiveness of air cooling decreases when the height position of the panel 3 the floor is low, and the gap between the floor panel 3 and the battery unit 100 cannot be extended. With this option, implementation, even if the height position of the panel 3 floor may not be a simple way increased, and the gap between the floor panel 3 and the battery unit 100 cannot be easily extended, the upper portion of the battery pack 100 can be cooled more effectively, through the front cooling jacket 20F placed in the gap.

As explained previously, in this embodiment, the front cooling jacket 20F is attached to the upper surface 12s of the battery cover 12 at a position located on the first segment 121 of the cover, which is the front section of the battery is nuclear biological chemical (NBC cover 12. As explained previously, the second group C and D batteries are placed in the longitudinally middle part of the battery pack 100 and have fewer stacked batteries 4 than any of the other groups of batteries. Meanwhile, the first group A and B batteries, placed in a more forward position, have a greater number of stacked batteries 4 than the latter group C and D batteries, and, thus, have a greater need for cooling. Therefore, the front cooling jacket 20F is attached to the front section 121 of the battery cover 12, which corresponds to the first groups A and B batteries.

In this embodiment, the passage 30 to the air flow is configured with the capability of providing a stream of air to flow from the front of the vehicle in the rear part of the vehicle when the vehicle is moving, and the front cooling jacket 20F and the rear cooling jacket 20R posted by protruding into the passage 30 for air flow. Thus, the air stream As flowing through the passage 30 for flow of air serves to cool the front cooling jacket 20F and the rear cooling jacket 20R and allows the battery unit 100 to cool more efficiently. Also, getting the cooling effect of the battery pack 100 through the air flow As the total cooling the battery pack 100 is increased, since it is cooled by liquid and air.

In this embodiment, the speaker up tunnel 52 is formed in the floor panel 3 of the floor and runs essentially in the longitudinal direction of the vehicle 1. At least the section of the passage 30 for the flow of air is formed through the tunnel 52 in the floor. Thus, the cross-sectional area of the passage 30 to the air flow more in part formed through the tunnel 52 in the floor, and the air flow rate As can be increased in a simpler manner in this very section, thereby allowing the upper part of the battery pack 100 to be cooled more efficiently. Air flow As can also be sent through the tunnel 52 in the floor so that the air stream As it flows more smoothly and adheres closer to the desired route of flow. Also, although the tunnel 52 in the floor provided for piping and wiring, it can be used effectively to increase the passage 30 for the flow of air in a more efficient manner.

In this embodiment, deep down zheloboobraznogo section 125 is formed in the upper surface of the battery pack 100 and runs essentially in the longitudinal direction of the vehicle 1. At least the section of the passage 30 for air flow formitemscollection zheloboobraznogo section 125. Thus, the cross-sectional area of the passage 30 to the air flow more in part formed by zheloboobraznogo section 125, and the air flow rate As can be increased in a simpler manner in this very section, thereby allowing the battery unit 100 to cool more efficiently. Also the air flow As directed by zheloboobraznogo section 125 so that it flows more smoothly and adheres closer to the desired route of the stream.

In this embodiment, at least a portion of the upper plate 12u, serving as the top wall of the battery cover 12 is made of heat conducting material, and the front cooling jacket 20F is placed in the transverse middle portion of the upper surface 12s of the top plate 12u. As a result, the cooling effect of the front cooling jacket 20F can be spread over a larger area using the top plate 12u, made of heat conducting material, and variation (unevenness) of the cooling effect on the left and right sides of the front cooling jacket 20F, resulting in that the front cooling jacket 20F is in the transversely middle section can be suppressed.

In this embodiment, the top plate 12u (which serves as the upper wall and cumulating cover 12), acts up so that the transverse middle portion, where the front cooling jacket 20F, is in the highest position. With such convex shape of the temperature of the air inside the space S of the battery casing 10 is highest in the highest position within the space S, i.e. in the upper section of St transverse middle part of the space S.
