Long Life Rechargeable Lithium Lifepo4 Battery For New Energy Car

Introduction

New energy vehicles are mainly composed of battery drive system, motor system, electronic control system and assembly. Among them, the motor, electronic control and assembly are basically the same as those of traditional cars. The reason for the price difference lies in the battery drive system. In terms of the cost composition of new energy vehicles, the battery drive system accounts for 30-45% of the cost of new energy vehicles, while the power lithium battery accounts for about 75-85% of the cost composition of the battery drive system.

Power battery management system

1. Electric vehicles rely on electric energy to drive vehicles. The instantaneous power may be as high as hundreds of kilowatts, the voltage range is from tens of volts to hundreds of volts, and the current can also reach plus or minus hundreds of amperes. The charging and discharging of large current and the output of high voltage mean that the power battery pack has high electrical load requirements.
2. In addition, the whole power battery pack is composed of many power battery cells. In order to effectively manage these power batteries, control the charge and discharge of the power battery pack, and respond to the functional requirements of the whole vehicle, the power battery pack also has a very complex power battery management system (BMS), which is composed of sensors, actuators, controllers (electronic control units) and other components, Collect the voltage, current, temperature and other data of the system, conduct complex calculation, communicate with other parts of the whole vehicle, complete specific functions, determine the operation boundary of the system, control the abnormal state of the system, etc.
3. Power battery management system can be regarded as the "brain" of power battery, which is mainly composed of single monitoring unit and power battery management unit. Firstly, the single monitoring unit is responsible for measuring the voltage, current, temperature and other parameters of the power battery, as well as equalization and other functions. When the unit monitoring unit measures these data, it transmits the data to the power battery management unit through the power battery "neural network" mentioned above.
