For
Lithium Ion Rechargeable Battery Charger
Conception
Lithium ion rechargeable battery charger can adjust and control the charging parameters with its
constant current & voltage charging mode. Along with BMS, it can protect the Li-ion batteries under
the following circumstance: Over Voltage (OV), Under Voltage (UV), Over Current (OC), Short Circuit
(SC) and Over Temperature (OT), and/or emergencies.
Before charging, when any cell in the battery pack appears OV, charging will be prohibited
automatically. Recharging can be started unless the failure is solved.
During charging, when any cell in the battery pack appears OV, OC, OT, BMS should give signals,
and the charger will automatically adjust the charge voltage and current to prevent the cells from OV,
OC.
During charging, if the operating termperature is too low, BMS will give signals to warn the users
that they should take actions, and adjust charging methods at low temperature according to the
Instruction Manual for Lithium Power Battery (hereinafter “Li Battery Manual”).
During charging, if any abnormal circumstance occurs, such as too high voltage, BMS short
circuit, too high temperature and so on, BMS will give signals, burn out the main circuit fuse and cut
the power supply to the charger.
Charging mode, methods and controlling functions
1. Charging mode
Constant current & voltage charging mode
2. Charging methods and controlling functions
1) Constant current charging mode
In the beginning of charging, charge the cells under constant curent at its limit maximum
(Generally, max curent 0.3CA, CA means the charge and discharge current, C means Capacity, A
means Ampere, 0.3CA means the current is 0.3 times of the capacity). During constant current charging,
the charge current keeps the same, but the charge voltage will gradually increase until it reaches the
limit maximum charge voltage.
2) Constant voltage charging mode
When the charge voltage reaches the limit maxium charge voltage (according to the Li Battery
Manual ), then it will be under constant voltage charging mode. At this moment, charge current will
decrease as time goes by. When it reaches at 0.015CA, charging stops. You can refer to the following
charging procedure chart, it shows the relation among charge voltage, current and capacity.
