Charging

Crown Battery Manufacturing Company specifies the following standard battery charge profile for the CR-215 deep cycle battery when used in an electric vehicle service:

Phase 1: Constant Current (I1)
I1 = highest amperage available < 60 amps

Phase 1: Constant Current (I1)
I1 = minimum amperage available > 20 amps
Normal transition to Phase 2 at 2.37 Volts Per Cell.
Safety transition to END OF CHARGE of dV / dt <0V / 1 hr, dt = 1 hr.
(NEGATIVE SLOPE).
Timeout for Phase 1 = 10 hours.

Phase 2: Constant Voltage
(U2) U2 = 2.37 VPC
Normal Transition to Phase 3 at I2 = 5.0 amps or approximate.
Safety transition to END OF CHARGE of l dI/dt l < 0.4 amp / 1 hr, dt = 1 hr.

Phase 3: Constant Current (I3) I3 = 5.0 amps or approximate.
Normal transition to END OF CHARGE at 115 -118% of AH returned.

PLEASE CONTACT CROWN BATTERY MANUFACTURING COMPANY TO ADVISE THE SPECIFIC CHARGE TERMINATION METHOD USED.

Timeout for charging phases 1 - 3 at 16 hours.
Temperature compensation coefficient = +/- 3 mV / °C.
Recommended Equalization Charge: Every seven (7) days. 4 additional hours at a normal finish rate of 5.0 amps for 4 hours.
Safety transition to END OF CHARGE at a maximum voltage of 2.7 VPC.
