PURPOSE: To lessen the heat generating danger of a battery by setting a TCO discriminating temperature by measuring the initial temperature of the battery. CONSTITUTION: Voltage checking and short-circuit checking are performed in step S10. In step S20, the temperature of a battery is measured before the charging of the battery is started and the TC is set at 40 deg.C (TC=40 deg.C) when the temperature of the battery is <=20 deg.C, at 50 deg.C (TC=50 deg.C) when the temperature is 20-3O deg.C, and at 60 deg.C (TC=60 deg.C) when the temperature is >30 deg.C. In step 30, a rapid charge is started. In steps S41 and S54, TCO discrimination is performed. When the temperature of the battery exceeds the TC while the battery is charged, the boosting charge is interrupted. |
