Method and apparatus for providing continuous power to a battery powered device during battery transfer
First Claim
1. A battery transfer apparatus for providing continuous battery power to a battery powered device, said apparatus comprising:
- a housing separate from the battery powered device;
a battery interface in said housing, said battery interface comprising a first connector which receives a charged battery to be installed in the battery powered device and a second connector which receives a nearly discharged battery to be removed from the battery powered device;
an external connector extending from said housing which provides an electrical connection with the battery powered device; and
continuous power transfer means in said housing and electrically connected to said battery interface and said external connector for providing electrical power from the charged battery to the battery powered device while removing the nearly discharged battery from the battery powered device, and for providing electrical power from the nearly discharged battery to the battery powered device while installing the charged battery in the battery powered device.

Abstract
A battery transfer apparatus and method according to the present invention provides continuous battery power to a battery powered device while changing batteries. Battery power is provided to the battery powered device from a charged battery while a nearly discharged battery is removed from the battery powered device. Battery power is also provided to the battery powered device from the nearly discharged battery while the charged battery is inserted into the battery powered device. The nearly discharged battery may be prevented from draining power from the charged battery during the transfer operation. A battery charger and battery condition indicator may also be included.
