摘要： A discharge welding system for discharge welding a welding member such as a stud to a weld surface such as a battery terminal or strap. The discharge welding system generally includes a power source which is electrically connected to both a clamp and a retainer such as a collet. The clamp is utilized to secure a conduction member such as a washer against a weld surface such as a battery terminal or strap. The retainer is utilized to removably retain a welding member such as a stud which is adapted to be welded to the weld surface. A weld actuator is adapted to lower the retainer such that the welding member contacts the conduction member to complete an electrical circuit as an electrical current is discharged by the power source. The welding member is welded to the weld surface by the electrical current discharge.

摘要： Electrochemical cell battery system and associated methods of operation are provided based on the incorporation of a thermal suppression construct including a supply of cooling fluid dispensed in intimate contact with the cells disposed within an enveloping sealed enclosure. The electrochemical cells are connected electrically by bus bars to form a battery of cells. The bus bars support cooling by convection methods. The cells are allowed to float mechanically as they are charged and discharged while maintaining intimate thermal contact with the enveloping sealed enclosure through conduction and the bus bars through conduction. The system provides a method of cooling the cells by conduction and convection and that accommodates mechanical changes to both the cells and the enveloping sealed enclosure.
