A charge controller or a charging connection facilitates the technical process of charging batteries. A charge controller can be stored in the following places: in a charger, in a battery-operated device or in the battery itself.
Charge controllers: different types of batteries require different types of charging methods. This is achieved through power electronics in modern charge controllers - older charge controllers are also partly electro-mechanically operated. A charge controller prevents overloading and limits the charging current. More complex charge controllers use further parameters to control the charge: temperature, voltage, capacity, time, charging current.
Complex charge controllers can be implemented with a microprocessor or a specific IC charger. Charge controllers have the following functions: regulation of the voltage generated by the electric generator, overload protection through a high output current, reverse current protection.
