A battery charger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.
Charge times vary depending on the designed output of the charger, as well as the size and type of battery being charged. KEBO’s intelligent battery charger works a 3-stage charging scheme perfectly to accelerate the charging time and provide continuous charging. It can also detect the state of charge and condition of the battery.
The following description assumes a sealed lead acid battery charging.
The first stage is referred to as “bulk absorption”; the charging current will be large and constant and is limited by the capacity of the charger.
When the voltage on the battery reaches its outgassing voltage the charger switches to the second stage and the voltage is held constant.
The delivered current will decline at the maintained voltage, and when the current reaches less than certain level the charger enters its third stage and the charger output will be held constant. In the third stage, the charging current is very small and at the voltage the battery can be maintained at full charge and compensate for self-discharge.
