The basic elements of the power lithium battery intelligent management system are detailed

　　The most important component is the battery management system, which is an important link between power and electric vehicles. The basic functions of the battery management system are divided into three parts: detection, management and protection. Specifically, it includes functions such as data collection, condition monitoring, balance control, thermal management, and safety protection. The following are the basic functions of the power lithium battery management system introduced by Asian land travel technicians:

　　Function 1: Thermal management

　　The important function of the battery management system in thermal management is to accurately measure and monitor the temperature of the power lithium battery. When the battery temperature is too high, effective heat dissipation and ventilation can ensure the uniform distribution of the battery temperature field. At low temperatures, it can heat up quickly to keep the battery pack working properly.

　　Function 2: Balance control

　　Balance management helps maintain the capacity of the power lithium battery and control the depth of discharge. If there is no balance control of the lithium battery, because of the protection function of the battery management system, it will happen when a fully charged battery and other batteries are not fully charged or discharged, limiting the minimum charge for a single battery is not achieved. Once the power lithium battery is overcharged or overdischarged, an irreversible chemical reaction will occur inside the power lithium battery, which will affect the nature of the power lithium battery and thus affect the service life of the power lithium battery.

　　Function 3: Status monitoring

　　The state analysis of power lithium battery mainly includes two aspects of battery remaining power and battery aging degree, namely SOC evaluation and SOH evaluation. SOC allows the driver to obtain direct information about the impact of remaining power on the cruising range. At present, many studies are focused on SOC analysis to improve its accuracy. SOC analysis will be affected by SOH, and the SOH of power lithium battery will be continuously affected by factors such as temperature and current during use. Therefore, continuous analysis should be performed to ensure the accuracy of SOC analysis.

　　Function 4: Data collection

　　Data collection is the basis and prerequisite for the battery management system to realize other functions. The accuracy and speed of data collection can reflect the advantages and disadvantages of the battery management system. According to the collected data, analyze and process other functions of the management system, such as SOC status analysis, balance management, and thermal management.webcam factory

　　Function 5: Safety protection

　　Safety protection is the most important function in the entire battery management system. It is implemented on the basis of the first four functions. Important ones include over-current protection, over-charge and over-discharge protection, over-temperature protection and insulation monitoring.

　　This article introduces the basic functions of the power battery management system. The important purpose of the battery management system is to improve the utilization rate of the power lithium battery, prevent the power lithium battery from charging and discharging, extend the service life of the power lithium battery, and monitor the status of the power lithium battery. With the development of the battery management system, other functions will be added.
