Abstract
To propose a charging device capable of warming a battery without using the electric power of a battery when the battery is charged.SOLUTION: A charging device that is connected to a grid power supply, converts the supplied power, and charges a vehicle battery includes a heat transfer structure that transfers heat from the charging device to the battery through coolant, and a control device that controls the current flowing through the charging device. The control device executes a first process of monitoring the temperature of the battery, and a second process of increasing the current flowing through the charging device when the temperature of the battery is equal to or lower than a predetermined threshold.SELECTED DRAWING: Figure 6
