The invention provides a four-string power battery Bluetooth communication protection control system, which comprises four strings of batteries, a 4S protection plate, an ACU and a motor, and is characterized in that the 4S protection plate is connected with the four strings of batteries and is used for collecting voltage and temperature of the four strings of batteries and current on a bus, and the ACU is connected with the 4S protection plate through Bluetooth communication and is used for collecting related data information; a protection plate and a motor control plate are integrated on the ACU, and the ACU is connected with four strings of batteries and a motor controller; when a serious fault occurs, the ACU gives an alarm and controls the four strings of batteries to be powered off; when a slight fault occurs, the ACU gives an alarm and controls the motor to reduce the rotating speed. The ACU is a control panel integrating functions of a BLE repeater, a battery management system, a motor management system and the like. A mature BLE relay data summarization development, a mature Zhong BMS system and a mature battery car control system at the present stage are adopted to establish an evaluation system with high feasibility, so that the control system is more perfect and intelligent, and the use safety of the electric vehicle is improved.
本发明提供了一种4串动力电池蓝牙通讯保护控制系统,包括4串电池、4S保护板、ACU以及电机,4S保护板与4串电池相连用于采集4串电池的电压、温度及其母线上的电流,ACU与4S保护板通过蓝牙通讯相连用于采集相关数据信息,ACU上集成有保护板以及电机控制板,ACU与4串电池、电机控制相连;当发生严重故障时,ACU发出报警并控制4串电池断电;当发生轻微故障时,ACU发出报警并控制电机降低转速。本发明的ACU为集成有BLE中继器、电池管理系统、电机管理系统等功能汇总的控制板;采用成熟BLE中继数据汇总开发、成熟的中颖BMS系统和现阶段成熟的电瓶车控制系统,搭建可行性比较高的评估系统,使得控制系统更加完善、智能,提高了电动车的使用安全性。
