Abstract

A method of charging a battery, and particularly a nickel battery, in a mobile charger, such as a vehicular charger, which is subjected to elevated temperatures. The method includes the steps of a first charging of the battery until a temperature inflection occurs, and then ceasing the charging while the battery temperature stabilizes. Then the battery is charged a second time, and a parameter is monitored for an indication of a full charge, such as temperature inflection or voltage cut-off. Preferably, when the battery reaches an elevated temperature, the charging is ceased until the battery stabilizes, and the charger monitors either temperature inflection, voltage cut-off, or a Coulomb count to determine when the battery has a full charge.
