The battery management system (BMS) detects the quantity of running batteries utilized in full electric and hybrid cars with high-accuracy while also performing the monitoring and control of lithium batteries. The BMS controls charge and discharge, cell balance, high-voltage line connection, and cooling.
The management electronic control unit (ECU) calculates the required torque of the electric motor. The calculation is based on the amount of battery charge remaining that is reported by the battery management system and the user's desired accelerating profile. The calculations are supplied to the power control unit (PCU) that drives the motor as instructed while meeting the optimum total energy management in the electric vehicle control system.
An electronic control unit (ECU) for running overall vehicle functions, this unit detects the conditions of the accelerator and transmission and the environmental conditions, such as temperature and atmospheric pressure, from sensors in the vehicle. The ECU transmits necessary information, such as air requirement, fuel injection amount, and ignition timing, to other peripheral vehicle devices to insure proper operating conditions
The fuel cell (FC) power generation control unit maintains the balance between hydrogen gas and oxygen in the system of a fuel cell vehicle so that the fuel cell can generate electricity efficiently and safely.
An electronic control unit (ECU) that monitors the impedance of a fuel cell stack so that the amount of moisture contained in the stack can be maintained properly. Keeping the proper moisture content in the FC stack prevents stack deterioration and contributes to longer fuel cell stack life.
