摘要： An electric power tool includes a tool body and a battery pack. A terminal voltage setting unit of the tool body sets a voltage of a body side terminal to a first voltage when a command to drive a drive portion of the tool body is issued by a switch of the tool body. A voltage changing unit of the battery pack changes a voltage of a battery side terminal from the first voltage to a second voltage when supply of electric power from the battery pack to the drive portion is permitted.

摘要： A map is retrieved based on a battery temperature, a temperature rise value and an allowable current value, with which a battery can be charged while battery temperature rise is being suppressed, is obtained and the battery is charged with the allowable current value. By doing so, it is possible to charge a nickel metal hydride battery cell which temperature tends to rise during battery charge in a short time without causing deterioration due to temperature rise. This battery charger makes determinations after dividing the battery. Due to this, compared with a case of simultaneously determining all battery cells, it is possible to accurately determine the completion of charge.
