Title:
CHARGE CONTROL APPARATUS AND CHARGE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2022117354
Kind Code:
A
Abstract:
To provide a charge control apparatus and a charge control method that can prevent resistance burnout while reducing costs.SOLUTION: A charge control apparatus according to the embodiment comprises a resistor circuit whose resistance value can be changed and a control apparatus. The resistor circuit is provided in a charging path that charges a secondary battery from a power supply. The control apparatus variably controls the resistance value of the resistor circuit according to the voltage difference between the power supply and the secondary battery or the current flowing to the secondary battery, so that the current flowing to the secondary battery meets the battery requirements and the current value does not exceed the allowable loss of the resistive elements in the resistor circuit.SELECTED DRAWING: Figure 3
