Back-up power supply with replaceable battery pack
First Claim
1. An apparatus for providing back-up power in an electronic system, the apparatus comprising:
- (a) a fixed charger mounted in the electronic system, the charger including a charging circuit electrically coupled to the electronic system, a case housing the charging circuit, and a blind docking connector electrically coupled to the charging circuit; and
(b) a removable battery pack docked with the charger, the battery pack including a battery electrically coupled to the charging circuit through a blind docking connector mating with the connector on the charger and a case housing the battery to enclose the battery and thereby substantially restrict external access to the battery.

Abstract
A back-up power supply includes a fixed charger fixably mounted in an enclosure of a computer system and having a charging circuit electrically coupled to the computer system. The charger is mounted in a case which houses the charging circuit and provides EMC shielding. A removable battery pack is docked with the charger through cooperative blind docking connectors to electrically couple a pair of batteries with the charging circuit. The batteries are enclosed within a case to substantially restrict external access to the batteries. Preferably, the batteries together form an "L" shape, and the charging circuit is disposed on a circuit board having low and high profile areas. The batteries in the battery pack are disposed adjacent the low profile areas of the circuit board, such that the overall space required for the power supply is reduced.

11. A removable battery pack for docking with a fixed charger of the type having a charging circuit disposed on a circuit card and housed within a case, the circuit card of the type including a first portion having an oversized electronic component mounted thereto, and a second portion devoid of oversized electronic components, the battery pack comprising:
-
(a) first and second batteries; and (b) a case housing the batteries with the second battery extending generally orthogonal to the first battery and with the first and second batteries occupying a volume generally adjacent the second portion of the circuit card, the first and second batteries defining an "L" shape and thereby defining a notch in the case for receiving the first portion of the circuit card. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A computer system comprising a back-up power supply electrically coupled thereto, the back-up power supply comprising:
-
(a) a fixed charger mounted in the apparatus, the charger including a charging circuit electrically coupled to the computer system and an electromagnetic compatibility (EMC) shielded case housing the charging circuit; and (b) a removable battery pack docked with the charger through cooperative blind docking connections on the battery pack and the charger, the battery pack including first and second batteries electrically coupled to the charging circuit through the connections and a case housing the batteries to enclose the batteries and thereby substantially restrict external access to the batteries, wherein the charger shields the computer system when the battery pack is not docked to the charger. - View Dependent Claims (19, 20)
