Explain Constant current system

Constant current system: - In this process, the charging current is kept constant by varying the supply voltage to overcome the enhanced back emf of cells. If a charging booster is used, the current supplied by it can be kept back constant by adjusting its excitation. If charged on d.c. supply, the current is controlled by differ the rheostat connected in the circuit. The value of charging current should be so chosen that there would be no excessive gassing during last stages of charging and, also, the cell temperature does not exceed 450C. This method takes a comparatively longer time
