RELATIONSHIP BETWEEN CHARGE LIMITS AND TEMPERATURE
Due to the chemistry of lithium Ion cells, the cells cannot accept as much
charge current at lower temperatures without risking permanent loss of capaci-
ty� As the cell's temperature rises during the charging process, they can gradu-
ally accept higher currents�
CHARGE RATE BY TEMPERATURE
Temperature (°C)
-20 ~ -10
0 ~ 10
10 ~ 25
Maximum recommended continuous charge rate is 0,2 C�
INTEGRATED MODULE PROTECTION
The LiFePO4 battery module includes integrated protection circuitry to prevent
the battery module from exceeding its voltage limits� The module's circuitry
interrupts either charging or discharging current if the battery is in danger of
exceeding upper or lower voltage or temperature limits�
Over Voltage and Under Voltage
The modules circuitry continuously monitors cell voltage and can interrupt
either charge or discharge current in the event that a cell's voltage exceeds
safe operating limits� The over voltage and under voltage protection include
software/hardware protection�
Over voltage
MOSFET are used to control and will turn OFF and interrupt the charge current
when meet over voltage protection (The protection circuitry interrupts current if
the voltage on any single cell rises above 3�9 V�
For hardware protection: over voltage protection threshold is 3�9 V, the over vol-
tage protection recovers when voltage drops to 3�6 V�
Under voltage
MOSFET are used to control and will turn OFF and interrupt the discharge cur-
rent when meet under voltage protection (The protection circuitry interrupts
current if the voltage on any single cell falls below 2�3 V or 2�0 V
Hardware protection:
During discharging, when any cell's voltage falls below 2�0 V, the discharge
MOSFET turns OFF� Interrupt discharge current and under voltage protection
will recover when voltage reaches to 2�5 V�
