Abstract
A current regulation system for generating a charging current curve for charging a rechargeable battery is provided, the system including a current regulation module coupled to a power converter to output a conversion current in a constant current mode and a constant voltage mode, a voltage-to-current regulation module coupled to the rechargeable battery to output a voltage conversion current in the constant voltage mode, a temperature-to-current regulation module and a resistance. The temperature-to-current regulation module outputs a temperature conversion current in the constant current mode and the constant voltage mode. The resistance is coupled to the current regulation module, the voltage-to-current regulation module and the temperature-to-current regulation module to regulate the voltage conversion current or the temperature conversion current, the conversion current is weakened by maintain a constant value so the charging current curve is regulated when the power of the rechargeable battery is full.
