基于SX5256DH434PHEV型混合动力重型环卫车的电池管理系统浅谈

在全球能源危机的情况下,随着国际碳排放出口协定的实施,绿色清洁汽车已经成为发达国家当前汽车技术的发展方向,发达国家多数把锂离子电池作为EV、HEV、PHEV的新能源。由于汽车的复杂工况和锂离子电池电化学特性,一般需要完善的电池管理系统BMS(BATTERY MANAGEMENT SYSTEM),其作用是对锂离子电池电压、电流、温度、容量、电池的SOC荷电状态计量、电池与车体的绝缘状态等多种电池参数以CAN通讯的方式与车控电脑实时进行信息交换,确保电池的能量发挥到极致,使驾驶者能够随时掌握电池的工作状态,以保证电池的安全。BMS不仅是数字化智能电池系统的中枢神经,也是新能源汽车必不可少的关键部件。

Battery management system of type hybrid heavy sanitation vehicle

In the global energy crisis, with the implementation of the international carbon export agreement, green vehicle has become the development direction of the automotive technology in developed countries, the developed countries the majority of the lithium ion batteries as new energy EV, HEV, PHEV. Because of complicated and lithium ion battery electrochemical characteristics, needs the perfect battery management system BMS （BATTERY MANAGEMENT SYSTEM）, and its role is insulated and other parameters of the battery of lithium ion battery voltage, current, temperature, capacity, battery state of charge measurement, SOC battery and the vehicle body by CAN communication mode and vehicle control computer real-time information exchange, ensure the battery energy into full play, so that the driver can at any time to master the working status of the battery, in order to ensure the safety of the battery. BMS is not only the central nervous digital smart battery system, the key component is the new energy automotive essential
