TRANSPORT VEHICLE POWER SUPPLY SYSTEM Russian patent published in 2014 - IPC F02N11/08 

FIELD: electricity.

SUBSTANCE: invention is related to start systems for automobiles, railroad transport, and electric transport. A system contains an accumulator battery and an energy storage unit, a system monitoring and control module (SMCM), a voltage conversion module (VCM), a power switching module (PSM) for switching of direct-current power circuits. The system contains a charger intended for additional recharge of the accumulator battery and the energy storage unit made as an electrochemical capacitor (ECC). At that VCM is coupled by power circuits to power supply buses of the onboard network, PSM and SMCM; PSM is coupled by power circuits to the charger, MM and ECC and the charger in its turn is coupled to power circuits of MA and ECC. The system monitoring and control module can supply control signals to VCM, PSM and the charger and to receive signals from voltage sensors of the accumulator battery, the ECC voltage sensor and the charger current sensor as well as to control voltage/current of the power supply bus of the onboard network and to ensure exchange of information with the vehicle onboard data bus.

EFFECT: simplification of the system, reduction of dimensions and enhancing functional capabilities.
