The invention provides a storage battery charging and discharging control circuit and device and an automobile. The control circuit comprises a storage battery, a direct-current converter, a switch structure and a vehicle control unit. The switch structure comprises a control end; wherein the storage battery is connected with the switch structure, and the switch structure is connected with the direct-current converter; the input end of the vehicle control unit is connected with the storage battery, and the output end of the vehicle control unit is connected with the control end; the vehicle control unit is used for determining output voltage based on the electric quantity of the storage battery and outputting the output voltage to the control end. And the control end is used for switching on or off the switch structure according to the output voltage, so that the direct-current converter charges or does not charge the storage battery. According to the control circuit, charging or discharging control of the storage battery is realized, the problem caused by insufficient electric quantity or overcharging of the storage battery is avoided, and the problem of how to control charging and discharging of the storage battery is also solved; in addition, the vehicle control unit controls the switch structure to be switched on or switched off, the control accuracy is higher, and the effect is better.
本申请提供一种蓄电池充放电控制电路、装置及汽车。该控制电路包括:蓄电池、直流变换器、开关结构以及整车控制器;开关结构包括控制端;其中,蓄电池与开关结构连接,开关结构与直流变换器连接;整车控制器的输入端与蓄电池连接,整车控制器的输出端与控制端连接;整车控制器用于基于蓄电池的电量,确定输出电压,并将输出电压输至控制端;控制端用于根据输出电压闭合或断开开关结构,以使直流变换器为蓄电池充电或不充电。该控制电路实现了蓄电池的充电或放电控制,避免了蓄电池电量不够或过充电带来的问题,也解决了如何进行蓄电池充放电控制的问题;另外,由整车控制器控制开关结构的闭合或断开,控制精确度更高,效果也更好。
