Additional module 19, which is connected or can be connected to the basic module 18, as already mentioned, includes Converter 15 current interacting with electromachine 11, and the connection 25 to create electrical contact between the transducer 15 DC, hosted by the plug 19, and electromachine 11. Additional module 19 of the modular unit 17 power conversion can mechanically join the structure 28 of the body through core module 18. Besides what about this, additional module 19 can be cooled by the main module 18. Moreover, the Converter 15 current, which can be found in the supplementary module 19 and communicates with electromachine 11 may be connected to the inverter 14 current of the battery 13 electric energy through the basic module 18 and the Converter 16 DC, located in the base module 18.
