The following rules must be observed when modifying the parameter
values in User for lithium battery.
I.
Over Voltage Disconnect Voltage>Over charging protection
voltage(Protection Circuit Modules(BMS))+0.2V
※
;
II.
Over Voltage Disconnect Voltage>Over Voltage Reconnect Voltage
＝
Charging Limit Voltage ≥ Equalize Charging Voltage
＝
Boost Charging
Voltage ≥ Float Charging Voltage>Boost Reconnect Charging Voltage;
III.
Low Voltage Reconnect Voltage>Low Voltage Disconnect Voltage ≥
Discharging Limit Voltage;
IV.
Under Voltage Warning Reconnect Voltage>Under Voltage Warning
Voltage≥ Discharging Limit Voltage;
V.
Boost Reconnect Charging voltage> Low Voltage Reconnect Voltage;
VI.
Low Voltage Disconnect Voltage ≥ Over discharging protection voltage
(BMS)+0.2V
