Charger for Power Storage Device

A charger for a power storage device, the charger comprising:

• a power regulator configured to regulate power supplied from a power supply and output the power to a power storage device;
• a current detector configured to detect a battery current supplied from the power regulator to the power storage device;
• a voltage detector configured to detect a battery voltage between positive and negative electrodes of the power storage device;
• a controller configured to perform feedback control over the power regulator based on the battery current and the battery voltage, the controller switchable between constant current control and constant voltage control;
• a feedback signal generator configured to generate, based on the battery current and the battery voltage, a power feedback signal usable for the constant current control and the constant voltage control;
• and
• a feedback calculator configured to generate, based on a difference between a command value that is a target value of the battery current or the battery voltage and the power feedback signal, a control signal to control the power regulator through the constant current control or the constant voltage control.
