The invention provides a vehicle-mounted energy storage device, which is characterized in that a charge-discharge loop is arranged in series, a rectification loop is arranged to control the charge-discharge direction, and a pre-charge loop is arranged to regulate and control the charge current so as to reduce the charge-discharge pulse current and reduce the damage, and after the pre-charge is completed, before the charge is started, after the charge is started and before the discharge is started, the pre-charge loop is connected with the rectification loop to control the charge-discharge direction. And according to the state of the battery pack, the state and the stability of the battery pack are monitored in combination with preset charging and discharging conditions, so that the charging path and the discharging path are started after the time delay and when the charging and discharging conditions are met. According to the vehicle-mounted energy storage device, a charging and discharging path is started in a delayed mode in the control process from pre-charging and charging to discharging starting, after it is confirmed that the system is stable based on the charging and discharging conditions, the corresponding relay is started, and the next stage is started; the risk of oscillation caused by overlarge electric difference between the battery pack and the charger in the charging and discharging function starting moment of the charging and discharging collinear and same-port design can be reduced, the charging and discharging stability is improved, and the power supply performance is improved.
本发明提供一种车载储能装置,其将充放电回路串行设置,并设置整流回路控制充放电方向,以及设置预充回路调控充电电流,以降低充放电脉冲电流,降低损伤,其中,在预充电完成后、开启充电之前,以及充电开启后、放电开启之前,还根据电池组的状态,结合预设的充放电条件监测电池组的状态和稳定性,以在延时后,且满足充放电条件时再开启充电路径和放电路径。本发明的车载储能装置在预充电、充电至放电开启的控制流程中延时开启充放电路径,并基于充放电条件确认系统稳定后,再开启对应的继电器,进入下一阶段,可降低充放电共线同口设计在充放电功能开启瞬间、因电池组与充电机的电差异过大出现振荡的风险,提高充放电稳定性,提高电源性能。
