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.
