US Classification:

429129, 320112, 320116, 429163, 429164, 429169, 429151

Abstract:

A battery pack, charger, and terminal blocks for the pack, charger and a cordless power tool are provided. The pack includes battery cells disposed between end caps within a bottom housing of the pack, and a potting boat for housing pack electronics electrically connected to the cells between the end caps and disposed within a pack top housing. A pack terminal block is connected to the potting boat within the top housing. The charger and the power tool each include a terminal block for providing electrical connections between the charger/tool and the battery pack. The terminal block is configured to float side-to-side to provide displaceable movement of the terminal block within the charger housing or tool housing for aligning the battery pack terminal block therein.

International Classification:

H02J 7/00
H02J 7/04

US Classification:

320107, 320115, 320112, 320113

Abstract:

In a cordless power tool system, high temperature gases created in a battery pack by the battery cells during a charging or discharging operation can be routed into a housing of one of an attached power tool or charger to reduce the temperature of the gases, prior to venting the gases externally. In an example, a battery pack has at least one vent hole for relieving pressure and a movable device covering the vent hole and configured to expose the vent hole upon a pressure set-point within the pack housing being exceeded. In another example, the pack housing includes a thin-walled section designed to break if pressure within the pack housing exceeds a given pressure setpoint. In a further example, the pack housing includes a baffle having an S-shaped cross-section for providing a vent path for gases and for preventing external fluids from entering the pack housing.

International Classification:

H02J 7/00

US Classification:

320112000

Abstract:

A battery charger is provided which includes a housing formed by an upper housing half-shell and a lower housing half-shell connected together so that the half-shells align with one another, an opening for inserting a battery pack and an electrical cord extending form the housing. The upper and lower housing half-shells each include an indent area. The indent areas are in alignment with one another so that the electrical cord wraps around and occupies the indent areas. The lower housing half-shell includes a plurality of connections to secure a printed circuit board (PCB) therein to the half shell.

International Classification:

H01M 2/24

US Classification:

429158000, 429061000, 429007000

Abstract:

A cell connection strap for electrically connecting a pair of adjacent battery cells within a battery pack includes, in one example, a fusible link for preventing a thermal runaway condition from occurring in a cell connected thereto. The strap may include raised features thereon for permitting relative movement between the cells in the pack due to vibration or an impact of the pack from translating stress to welds connecting the straps to the cells. In another example, the body of the cell strap may include slits formed in sides thereof to reduce rigidity of the strap for protecting the welds between strap and cell, and also provides a fusible link capability in the strap for preventing a thermal runaway condition from occurring in a cell connected thereto.
