Abstract: The present invention relates to a power management system of a pure electric vehicle powered exclusively by batteries which allows the vehicle to carry a load of up to 13 tons, where the system of the present invention is provided with five blocks: a battery system (SBAT) (3), a control and power logic unit (ULCP) (4), a traction system (STR) (5), an auxiliary system (SAX) (36), and a driver's control panel (PCM) 81, where such blocks are interconnected by two buses, CAN bus (128) and Digital/Analogical BDA (129). The battery system has two battery banks (1) and (2) in parallel which are monitored by the BMS (76). The BMS (76) checks whether the voltages at the output of the batteries are the same as the input of the inverter (8) and manages the use of the battery banks in conjunction with the eVSI (73) by operating the battery bank (1) or the battery bank (2) or both depending on the load conditions of each bank.

Abstract: A hybrid vehicle control and operating system, a hybrid vehicle operated by the system, and a power supply arrangement for the hybrid vehicle where the drive of the hybrid vehicle is performed only by an electric motor driven by a generator under average power conditions and, under maximum power conditions, is driven by the generator and also by a battery bank that provides complementary energy to the electric motor. The bank of batteries accumulates energy exceeded by the generator and/or electric motor when the vehicle is under deceleration conditions or even stopped. The generator is driven by an internal combustion engine that supplies mechanical energy to the generator so that it can supply electric power to the electric motor and to the battery bank.
