Device and method for power compensation in vehicle by means of capacitor with high capacitance. RU patent 2521589.

FIELD: electricity.

SUBSTANCE: invention is related to power supply units of vehicles. The device and method are suggested for compensation of electric load power in a vehicle by means of a capacitor with high capacitance. The capacitor with high capacitance discharges current rapidly in order to compensate power when voltage at the generator and accumulator output drops temporarily during motion of the vehicle, and the capacitor is charged by permanent power pulse in order to prevent instability of the accumulator voltage in result of the generator overload taking place when the capacitor is charged. Charge of the capacitor is stopped temporarily and it discharges current to compensate power of the electrical load if voltage drops at the accumulator battery terminals in result of electrical load at the charged capacitor thus leading to compensation of power supply instability, e.g. voltage drop, in real time mode.

EFFECT: increase in the vehicle power and prevention of temporary deceleration thus improving control characteristics for the vehicle, improving efficiency factor significantly, operational performance in regard to fuel and longer operational life of different electrical parts.

The technical field

The invention relates to a device and method of compensation power device power in vehicles through high capacity condenser.

The level of technology

Although modern cars show superior performance, especially near perfect combustion due to improvements of various details and technologies of management by software that uses electronic control unit, is still necessary technical improvements aimed at increasing the ratio of power and elimination of the factors affecting the stability of the electronic control unit.

Future efforts should be more concentrated on the development of technical methods and tools that can improve efficiency of fuel (that is, mileage, fuel consumption) and transport performance through the use of properly engine power depending on traffic moving vehicle.

For example, mileage, fuel consumption is expected to be increased by 15% or more by using ecological driving, that is, when the inefficient behavior when driving, for example, sudden acceleration, sudden start, sudden braking and driving with high speed. However, this method of increasing mileage, fuel consumption and inefficient, as the impact of conduct, maximizing fuel economy is very dependent on the driver, and the effectiveness of this approach is not always high.

Thus, the increase in mileage, fuel consumption by changing driving style, perhaps, is inefficient because it is unacceptable to ask the drivers to use these modes of driving regardless transport situations, for example, in the city centre.

To resolve these difficulties, the technology was developed, where the super capacitor attached to the battery in the vehicle and battery voltage stabilized by charging voltage of the capacitor.

Electrochemical double layer capacitors, representing capacitors, high-capacity, have an advantage over conventional batteries in that they served instantaneous peak power for a very short time (up to 100 times smaller than conventional batteries), although they can accumulate less energy than batteries.

If this advantage is applied to the battery, it allows to effectively cope with short-term drop battery occurring within a few seconds, through the submission of high quality energy supply at perceiving the load. This not only leads to stabilization of power, but also contributes to the battery, increasing the duration of its operation.

However, since the condenser high capacity with a large capacity from a few Farad to thousands Farad (f), the current in the range from tens to thousands of amperes (A) flows when a charged capacitor high capacity, leading to short-term reduction in voltage. In addition, the condenser, the high capacity also affects charging the battery voltage with the overloaded generator, which prevents the increase in mileage, fuel consumption, but increased power output and superior noise reduction.

Because the device power stabilization, just use standard condenser high-capacity overload battery or generator, adversely affecting the value of the mileage, fuel consumption, device power stabilization mainly use low-capacity capacitors, and not high capacity condenser. However, it was found that the low-capacity capacitors does almost no increase in mileage, fuel consumption and no improvement of operating characteristics at short-term reduction of battery voltage, since fuel consumption is determined after the electronic control unit of the vehicle performs the operation training.

Disclosure of the invention

Thus, the present invention was made in connection with the above difficulties, and the present invention is to create a device and method of power compensation devices power in the vehicle using the high capacity condenser, where the condenser high-capacity fast out of the current to power compensation, when the output voltage from the generator and the battery in the vehicle temporarily falls when the vehicle, and the high capacity condenser charged when using the charging pulse constant power to prevent instability battery voltage due to overloading of the generator for a charged capacitor high capacity and, in addition, high capacity condenser temporarily ceases charged condition and takes the current discharge to compensate power electric load in the vehicle in case of decrease of the voltage at the terminals of the battery by the electric load of the vehicle, when the condenser high capacity charged, and the advantage is that the instability of the power, such as reducing voltage, offset in real time, which increases the output power of the vehicle and prevents temporary slowdown, improving, thus, not only the characteristics of driving a vehicle, but also greatly increasing the efficiency of fuel performance and duration of operation of various electrical components.
