CHARGE CONTROL DEVICE

摘要

A charge control device includes a voltage detector that detects a voltage of a battery, a temperature detector that detects a battery temperature, a voltage setting unit that sets at least one of a charge completion voltage and an abnormality determination voltage to a high temperature time voltage that is lower than a normal voltage when the battery temperature detected by the temperature detector is or is above a high temperature determination threshold set in advance, and a charging current limiting unit that reduces a charging current a charger supplies to the battery when the battery temperature is in a temperature range between a set temperature that is lower by a predetermined temperature than the high temperature determination threshold and the high temperature determination threshold and the battery voltage detected by the voltage detector is in a voltage range between the normal voltage and the high temperature time voltage.

1. A charge control device that controls charging of a battery from a charger, the device comprising:
a voltage detector is configured to detect a voltage of the battery; a temperature detector is configured to detect a temperature of the battery; a voltage setting unit is configured to set at least one of a charge completion voltage and an abnormality determination voltage to a high temperature time voltage that is lower than a normal voltage when the battery temperature detected by the temperature detector is or is above a high temperature determination threshold set in advance, the charge completion voltage and the abnormality determination voltage being voltages set in advance in the charger so that charging of the battery is stopped when the battery voltage reaches the charge completion voltage or the abnormality determination voltage that is higher than the charge completion voltage set in advance; and a charging current limiting unit is configured to reduce a charging current a charger supplies to the battery when the battery temperature is in a temperature range between a high set temperature that is lower by a predetermined temperature than the high temperature determination threshold and the high temperature determination threshold and the battery voltage detected by the voltage detector is in a voltage range between the normal voltage and the high temperature time voltage, during charging of the battery by the charger.
