What are the detection methods for lithium battery pack maintenance board?portable battery generators

　　Many people do not understand the use of lithium ion battery maintenance boards. Lithium -ion battery maintenance boards, as the name suggests, are used to maintain lithium -ion battery packs. The use of lithium -ion battery maintenance boards is to maintain the battery There are short -circuit maintenance output.

　　The lithium -ion battery maintenance board is mainly used to maintain the charging and discharge of the lithium -ion battery pack. It can ensure that the voltage difference between the lithium -ion batteries of each monomer is less than the value of its setting. When the value is fully charged, the balanced charging of each single battery of the lithium -ion battery pack can effectively improve the lithium -ion battery pack composed of the string The charging effect,

　　At the same time, the maintenance board can also detect the overvoltage of each single lithium -ion battery in the lithium -ion battery pack, under pressure, overcurrent, short circuit, and over temperature conditions. After detecting these conditions, the maintenance board can be adjusted and rectified in time. The maintenance board can effectively maintain the service life of the lithium -ion battery pack.

　　The use of underwriting maintenance is to prevent a single lithium ion battery in the lithium ion battery dwellers damaged due to excessive discharge during discharge.

　　Maintenance board good or bad detection method:

　　1. Detection circuit

　　The functions of the maintenance boards of the lithium -ion battery sets produced by different manufacturers are not necessarily the same. Some maintenance board design has a thermist resistance to the lithium -ion battery pack over heat maintenance.

　　The dependent Ministry on the maintenance board only provides a temperature salty device for the road, and the fake maintenance board circuit is poorly connected. It is the beginning of the weight of the maintenance board.

　　2. Volks

　　After the multimeter to determine the correctness of the line wiring, the B-wire terminal and the multimeter red table red table red table pen-sized letter B1 line terminals were used to obtain a series of battery voltage with a universal table black table. This method is used to measure all parallel batteries in the lithium ion battery pack.

　　If the cable wiring is correct, and the power supply of all battery string is lower than a certain value, then it means that the maintenance board plays a role to ensure that the consistency of all batteries of the lithium -ion battery pack.

　　3. Measurement voltage

　　After measured the bell ions by the pool group from the pressure to recognize its main hall, inserting the line lines into the maintenance board test is the obstruction between the ports on both sides of the maintenance board. The right of the board is very useful.
