Abstract
A battery assembly having a plurality of battery modules capable of powering a traction motor of a vehicle. First and second end frames are provided on the battery modules. A plurality of battery cells is disposed between the first and second end frames. The first end frame of one of the battery modules has a first pocket. The second end frame of an adjacent battery module has a second pocket. The first and second pockets are aligned when the battery assembly is assembled to define a receptacle. A thermistor is disposed in the receptacle. The thermistor extends through the first pocket of the first end frame and at least partially into the second pocket of the second end frame.
Claims15
A battery assembly comprising:
- a plurality of battery modules having first and second end frames, wherein the first end frame of one of the battery modules defines a first pocket, and the second end frame of an adjacent battery module defines a second pocket;
- a plurality of battery cells disposed between the first and second end frames;
- and
- a thermistor extending through the first pocket to contact at least one of the battery cells of the one of the battery modules, and further extends only partially into the second pocket of the adjacent battery module.
A method of assembling a battery assembly, comprising:
- attaching a thermistor to a battery cell disposed within a first battery module through an aperture in a first end frame;
- and
- attaching a second end frame defining a pocket of a second battery module to the first end frame such that the thermistor extends all the way through the aperture and only partially into the pocket.
A battery assembly for a vehicle, comprising:
- a first battery module including a plurality of battery cells and a first end frame defining an aperture;
- a second battery module adjacent to the first battery module and having a second end frame adjacent to the first end frame;
- and
- a thermistor attached to one of the battery cells, wherein the thermistor extends through the aperture and only partially into the second end frame.
