摘要:
A filtered electrical connector for a power module comprises a connector body having a back wall partly defining a chamber at one end of the connector body. An alternating current filter is retained in the chamber, and a terminal extends through the back wall, the chamber, and the alternating current filter disposed in the chamber. The filtered electrical connector is attached to a housing having a metal portion with the chamber disposed in a pass-through hole of the housing. The terminal is attached to an electrical circuit inside the housing and the alternating current filter is grounded on the metal portion of the housing to filter alternating current flowing outside of the housing from the electrical circuit inside the housing via the terminal.

An electrical connector has a connect or shroud. A pin block disposed in the connector body supports a plurality of terminal pins that have head portions projecting out a forward end of the pin block and tail portions projecting out a rearward end of the pin block. The connector shroud has a socket at a forward end that receives a terminal stabilizer that is locked to the pin block to hold the terminal stabilizer and the pin block in assembly with the connector shroud to form a module. The module may include a block seal that can be sandwiched between the terminal stabilizer and the pin block during assembly of the module. The rear end of the connector shroud is truncated at an angle for a direct top down assembly of the module to a housing that has an attachment collar that is truncated at the same angle. The pin terminal tail portions are bent at a right angle and project through holes in a pin alignment member and a printed circuit board that are mounted inside the housing.

A multi-pin electrical connector including a first connector portion and a second connector portion. Seal retaining rings snapped into the connector portions seal and retain cavity terminal blocks located within each respective connector portion. A locking collar employs a ramped locking feature to snap and secure the first and second connector portions in an interlocked, assembled state. The multi-pin electrical connector can be composed entirely of non-metallic components.

A printed circuit board supported over the top surface of a multi-cell battery module for battery cell voltage and temperature monitoring has an array of openings in alignment with selected battery cells for receiving temperature-sensing units that electrically couple with contacts formed on the printed circuit board and resiliently engage the cases of the selected battery cells. Each such temperature-sensing unit includes a printed circuit board mountable lamp socket and a lamp socket insert including a thermistor and a compressible element that maintains the thermistor in thermal proximity to the battery cell case when the temperature-sensing unit is installed in a respective printed circuit board opening.

A pressure connection apparatus includes a conductive spring member having first and second end portions that are curved, and first and second retaining members having curved pockets that are oppositely oriented for receiving the first and second curved ends of the conductive spring member. An aluminum foil terminal of one battery is sandwiched between the conductive spring and the pocket of the first retaining member, while a copper foil terminal of another battery is sandwiched between the conductive spring and the pocket of the second retaining member. The spring member is clad with aluminum on one side and copper on the other, and the end portions are oppositely curved so that the aluminum-clad side contacts the aluminum foil terminal within the pocket of the first retaining member, and the copper-clad side contacts the copper foil terminal within the pocket of the second retaining member.

A voltage tap apparatus functions as both a voltage tap and a cell isolator for conductive case battery cells that are joined end-to-end in a series chain. The apparatus includes conductive leadframe elements partially encased in a plastic frame that engages the joined cells about their juncture, with portions of the lead-frame elements exposed to electrically contact the conductive cases of the cells. In a first embodiment, the plastic frame is in the form of a hinged clamp that closes about the juncture of the cells, and the lead-frame elements are routed to terminals formed on one end of the frame. In a second embodiment, the plastic frame and a connector are mounted on a printed circuit board and the leadframe elements in the plastic frame couple the battery cells to the connector.

A prismatic-cell battery pack is provided with integral coolant passages including an intake plenum, an exhaust plenum, and a distributed array of coolant channels coupled between the intake plenum and the exhaust plenum. Coolant medium forced into the intake plenum enters the coolant channels in parallel, draws heat away from the battery cells, and then enters the exhaust plenum for expulsion into the atmosphere. The battery pack is configured as a set of stackable interlocking battery cell modules including at least one battery cell in thermal proximity to an array of coolant channels distributed over the profile of the battery cell, and a pair of peripheral chambers joined to opposite ends of the coolant channels to form the intake and exhaust plenums when the modules are arranged and interlocked in a lineal stack.

A battery assembly is designed to include a plurality of cells positioned parallel to each other. A frame including end supports position the cells appropriately. Each of the cells includes a first terminal and a second terminal. Two buses are positioned over all of the first terminals and all of the second terminals. Each of the buses includes slots allowing the terminals to extend therethrough. Once through, the terminals are bent over the bus bar. A slide is then positioned over the terminals protecting the terminals and maintaining the terminals in electrical contact with each other. This battery assembly allows more than three cells to be connected to each other and is versatile enough to allow the removal of certain cells to enhance the airflow through the battery assembly.
