The invention relates to the technical field of lithium battery protection plates, and discloses a two-wheeled electric vehicle lithium battery protection plate function expansion design scheme, which comprises a protection plate system, and the system is composed of a protection function plate and an expansion function plate; wherein the protection function board comprises an analog front-end chip, a sampling equalization circuit, an MOS (Metal Oxide Semiconductor) driving circuit, a charging MOS and a discharging MOS; the expansion function board takes a single-chip microcomputer as a core, and communicates with the analog front-end chip of the protection function board in an IIC or SPI communication mode so as to acquire the acquired single voltage and current. Through the separated design, the expansion function of the protection plate is subjected to universal design, and the problems that a traditional customized protection plate is limited in function, various in model number, long in material preparation and production period and the like are solved.

    本发明涉及锂电池保护板技术领域,且公开了一种两轮电动车锂电池保护板功能扩展设计方案,包括保护板系统,所述系统由保护功能板和拓展功能板两部分构成;其中保护功能板包括由模拟前端芯片和采样均衡电路,MOS驱动电路及充电MOS和放电MOS;拓展功能板以单片机为核心,通过IIC或者SPI通信的方式与保护功能板的模拟前端芯片进行通信,以获取采集到的单体电压和电流。本发明通过分离式设计,对保护板拓展功能进行通用性设计,解决了传统定制式保护板的功能有限,型号繁多,备料及生产周期长等问题。
