The invention relates to an electric energy management device for a 24V storage battery of a commercial vehicle. The electric energy management device is mainly composed of a metering chip U1, an MCU,a manganin sampling resistor R1, an electromagnetic power supply main switch S1, an electromagnetic power supply main switch S2, a mechanical main switch S3 and an engine ECU. Voltage, current and consumed electric energy data can be accurately collected through the metering chip, electric equipment except the engine ECU is turned off according to the electric energy consumption condition, the power supply of the engine ECU can be turned off when necessary, and it is guaranteed that the storage battery can provide enough electric energy during next ignition. Intelligent management of electricenergy of the storage battery can be achieved, enough electric energy is provided for vehicle ignition, the number of times of vehicle breakdown is reduced, the problem that the electric energy of the storage battery is exhausted when a driver forgets to turn off a main power supply or does not use the vehicle for a long time can be avoided, and the service life of the storage battery is effectively prolonged.
本发明涉及一种商用车24V蓄电池电能量管理装置,主要由计量芯片U1、MCU、锰铜采样电阻R1、电磁电源总开关S1、电磁电源总开关S2、机械总开关S3、发动机ECU组成;通过计量芯片可以准确采集电压、电流以及消耗电能量数据,根据消耗电能情况关断发动机ECU以外的用电设备,必要时可以关断发动机ECU电源,保证在下一次点火时蓄电池能够提供足够电能。可以实现蓄电池电能量智能管理,给车辆点火提供足够电能,减少车辆抛锚次数,可以避免因司机忘关总电源或者长时间不使用车辆量时导致蓄电池电能消耗殆尽的问题,有效延长蓄电池使用寿命。
