Assignee:

EnerDel, Inc. - Indianapolis IN

International Classification:

B23K 31/02

US Classification:

228261, 427455, 427192

Abstract:

A process for physically bonding two parts to each other is disclosed. In addition, a process for forming electrical connections have a low resistance is disclosed. The process is generally applicable to the joining of two parts each formed from a metal, an alloy, or a combination thereof. The process finds special use in the formation of multi-celled batteries. The process involves placing two parts or electrical conductors in contact with each other and then bonding them to each other using a kinetic spray process and powder particles. In formation of a multi-celled battery the particles are preferably electrically conductive. The process enables for rapid and cost effective formation of a physical connection. In addition, the connection can have an electrical resistance of less than about 0. 5 milli Ohms and strength equal or greater than ultrasonic welding.

US Classification:

429 7, 36167901, 361752

Abstract:

A battery pack containing a plurality of battery cells having a housing and defining an opening within the housing and a battery control module configured to be disposed within the opening of the battery pack. The battery control module may contain circuitry for controlling a connection between the battery pack and an electric load or electric source and for controlling the charging of the battery cells. The circuitry within the battery control module is connected by rigid conductors, such as conductive traces on a circuit board or bus bars rather than flexible wire cables. The battery control module may be configured to be removed for serving the battery pack without removing the battery pack housing. The battery pack may further include a battery voltage monitor configured to monitor a terminal voltage of each battery cell and send a digital signal representing the voltage to the battery control module.
