Adapter circuitry for enabling charging and/or recharging a device or battery of a different type

摘要

An electronic adapter circuit for charging and/or recharging a battery of a first battery type utilizing a charging device for a battery of a second different battery type, may comprise: an electronic circuit for controlling the charging of the battery of the first battery type when the battery of the first type is charged by the battery charging device, wherein the electronic circuit has high conductivity when the battery of the first type provides electrical power to a load, and has a reduced conductivity for limiting charging of the battery of the first type when it is charged by the battery charging device. The electronic circuit may include a controllable conductivity device having high conductivity when the battery of the first type provides power to a load, and a battery charging control circuit for reducing the conductivity of the controllable conductivity device for limiting the charging of the battery.
