ABSTRACT:
A regenerative charge control system includes a cell, an inverter for converting a discharge power of the cell into a load driving force when a load is driven and for inverting the load driving force into the discharge power of the cell when the power is regenerated by the load, a voltage sensor for detecting a voltage between both ends of the cell, a current sensor for detecting a current passing through the cell, and a controller for measuring a discharge voltage and a discharge current of the cell by means of the voltage and current sensors when the load is driven. The controller estimates an allowable regenerative power when the power is regenerated on the basis of the measured results, and controls the charging power of the cell when the power is regenerated so as not to exceed the allowable regenerative power.
