Charger for nickel cadmium battery, has controller that changes charging current to minimum/maximum current based on cooling effect by cooling fan, to suppress battery temperature due to charging operation

摘要

A controller changes the charging current to a minimum charging current, when there is no cooling effect by the cooling fan and the battery temperature reaches a predetermined value. The controller changes the charging current to a maximum charging current, when there is cooling effect by the cooling fan and the battery temperature reaches a maximum value.
