The invention provides a power battery protection plate and a power battery protection system, and relates to the technical field of power batteries, the power battery protection plate comprises a central processing unit, a battery protection chip, a discharge switch tube and a charge switch tube; according to the power battery protection plate provided by the invention, on the basis of the battery state information acquired by the battery protection chip, the central processing unit can flexibly control the on-off of the charging switch tube and/or the discharging switch tube by sending the control instruction so as to protect the battery module. The charging switch tube and the discharging switch tube are connected in series on the same line, so that the power battery protection board not only realizes that charging and discharging share the same interface and simplifies the hardware structure of the power battery protection board, but also saves the hardware cost by replacing the function of a relay in a traditional power battery system with the switch tubes, The technical problems that a power battery system in the prior art is complex in hardware structure and high in cost are effectively solved.
本发明提供了一种动力电池保护板和动力电池保护系统,涉及动力电池的技术领域,包括中央处理器,电池保护芯片,放电开关管和充电开关管;本发明提供的动力电池保护板,基于电池保护芯片采集到的电池状态信息,中央处理器通过发送控制指令,能够灵活控制充电开关管和/或放电开关管的通断,对电池模组进行保护。通过将充电开关管和放电开关管串联在同一条线路上,该动力电池保护板即实现了充放电共用同一接口,简化了动力电池保护板的硬件结构,又通过使用开关管代替传统动力电池系统中的继电器的功能,节约了硬件成本,有效的缓解了现有技术中的动力电池系统存在的硬件结构复杂、成本较高的技术问题。
