Abstract
A battery pack for an electric or hybrid vehicle having battery connectors for connecting batteries in series and a battery connector are disclosed that reduces the risks of potential electric shocks during assembly, servicing and in emergency situation. The battery connector includes an interrupter having disconnect capabilities in the event of the vehicle being involved in a collision.
Claims8
A battery pack for electric or hybrid vehicle having multiple batteries connected in series by battery connectors, each battery having a positive and a negative pole;
- each battery connector comprising:
- a pair of battery pole covers made of an electrically insulating material mounted onto battery poles of two adjacent batteries, each battery pole cover having a receptacle area and an aperture providing access to the battery poles;
- a connect-disconnect safety device having a conductive element made of an electrically conductive material inserted into the receptacle area of the pole covers for electrically connecting the two adjacent batteries, and an interrupter, a central portion of the conductive element passing through the interrupter, the interrupter including a pyrotechnic charge and a mechanical cutter adapted to cut the central portion of the conductive element in the event of the vehicle being involved in a collision, thereby disconnecting the series connection of the batteries;
- and
- a pair of fasteners for securing the conductive element to the poles of the two adjacent batteries.
A battery connector for connecting a plurality of batteries in series to form a battery pack, the battery connector comprising:
- a pair of battery pole covers made of an electrically insulating material for mounting onto battery poles of two adjacent batteries, each battery pole cover having a receptacle area for providing access to the battery poles and an aperture;
- a connect-disconnect safety device having a conductive element made of an electrically conductive material inserted into the receptacle area of the pole covers for electrically connecting the two adjacent batteries, and an interrupter, a central portion of the conductive element passing through the interrupter;
- the interrupter including a pyrotechnic charge and a mechanical cutter adapted to cut the central portion of the conductive element in the event of the vehicle being involved in a collision, thereby disconnecting the series connection of the batteries;
- and
- a pair of fasteners for securing the connecting bridge to the poles of the two adjacent batteries, each fastener positioned inside one of the pair of battery pole covers, each fastener including a threaded portion made of metal and an electrically insulated portion made of a non-conductive material, the electrically insulated portion of the fasteners being accessible through the apertures of the battery pole covers.
