A battery pack of an electric or hybrid motor vehicle, which is constituted by an upper casing and a lower casing, is provided with a cooling circuit which enables circulation in the pack of a cooling fluid which is intended to be sprayed onto battery modules by spray nozzles. The cooling circuit is suitable for ensuring circulation of the cooling fluid in a closed circuit inside the pack, with a pump which is arranged in the internal vessel of the pack being capable of recirculating, back to the spray nozzles, the cooling fluid which is sprayed onto the modules and collected in a double base arranged under a base wall of the lower casing by discharge openings which are formed in the base wall of the lower casing.

A power tool system includes a removable battery pack a first tool and a second tool. The first tool includes a first base housing that is selectively engageable with the removable battery pack and a first tool portion connected to the first base housing by a first connecting section. The second tool includes a second base housing that is selectively engageable with the removable battery pack and a second tool portion connected to the second base housing by a second connecting section. The second tool base housing houses a second controller that provides a proportional power delivery system for the second tool and second tool base housing also includes a second actuator for providing user control of the second tool.

A battery module including a battery cell stack, which includes a plurality of battery modules; a busbar frame mounted on each of a front surface and a rear surface of the battery cell stack; a flexible printed circuit board unit to which a temperature sensor for measuring the temperature of the battery cell stack is attached; and a reinforcing sheet attached to the flexible printed circuit board unit.

A medical fluid pump with an upper housing shell, a lower housing shell and a front lid pivotably hinged to the lower housing shell. An energy storage compartment is formed on the lower housing shell which is provided and formed to receive an energy storage.

A vehicle battery assembly having specialized fasteners that includes an integrated compression limiter. The compression limiter provides protection for the fastening joint of a cover and a tray of a housing for the battery assembly. The battery assembly may also include nut and bolt assembly which may be installed by a nut insertion tool. The nut insertion tool allows the nut and bolt assembly to be installed without damaging the tray or the cover.

Provided is a battery pack comprising a plurality of batteries; and a plurality of memories that correspond respectively to the batteries and that each record deterioration information of the corresponding battery. Each set of a battery and a corresponding memory may be formed integrally as a battery cell. As a result, the deterioration information of each battery cell can be known even after the battery pack is disassembled.

A system for thermal management and structural containment includes a first battery cell having first and second terminal ends, and a first capillary void matrix disposed about an outer casing of the first battery cell.
