The invention relates to the technical field of vehicles, and particularly provides a lithium ion battery recognition device, management system and method.The recognition device comprises a first lithium ion battery, a control module and a CAN bus, and the first lithium ion battery is grounded through a pin; the control module is used for obtaining position information of the battery according to the grounding signal and sending the position information to the CAN bus; and the CAN bus is used for identifying the first lithium ion battery according to the position information. According to the invention, the grounded pin is additionally arranged between the two lithium ion batteries, and the grounded pin is used as an addressing line, so that the development difficulty and cost of the low-voltage battery are greatly reduced, the output voltage of the DCDC can be reversely adjusted according to the charging current of the DCDC, and the charging efficiency of the battery is improved. And the voltage drop of the charging loop and the voltage monitoring error caused by the resistance of the wire are avoided.

    本发明涉及车辆技术领域,具体提供一种锂离子电池的识别装置、管理系统和方法,本发明识别装置包括第一锂离子电池、控制模块和CAN总线,其中,所述第一锂离子电池通过引脚接地;所述控制模块用于根据所述接地的信号获得所述电池的位置信息,并将所述位置信息发送至CAN总线;所述CAN总线用于根据所述位置信息识别所述第一锂离子电池。本发明通过在两个锂离子电池中增加接地的引脚,将所述接地的引脚作为寻址线,这种设计,让低压电池的的开发难度和成本大大降低,本发明还可以以DCDC充电电流为根据去反向调整DCDC的输出电压,避免由于导线本身的电阻引起的充电回路的压降和电压监测的误差。
