High temperature battery system for hybrid locomotive and offhighway vehicles
First Claim
1. An electric storage battery system carried on a hybrid energy off-highway vehicle including wheels for supporting and moving the vehicle, an electrical power generator, and traction motors for driving the wheels, with electrical power generated on the vehicle being stored at selected times in the electric storage battery system and discharged from the electric storage battery system for transmission to the traction motors to propel the vehicle, with the vehicle and battery system being exposed to a range of environmental conditions, the storage battery system comprising:
- at least one battery for storing and releasing electrical power, wherein the at least one battery generates an internal battery operating temperature that exceeds the highest environmental temperature of the vehicle.

16. An electric storage battery system carried on a hybrid energy off-highway vehicle including wheels for supporting and moving the vehicle, an electrical power generator, and traction motors for driving the wheels, with electrical power generated on the vehicle being stored at selected times in the electric storage battery system and discharged from the electric storage battery system for transmission to the traction motors to propel the vehicle, with the vehicle and battery system being exposed to a range of environmental conditions, the electric storage battery system comprising:
-
at least one battery to store and release electrical power, with the battery operating at an internal battery temperature for effective storage and release of electric power, constituting an effective battery temperature, that is above that of the environmental temperatures of the vehicle and battery system, and with the battery cooling to a temperature lower than its effective internal operating temperature when the vehicle is out of service for extended period of time;
a monitor for sensing a parameter indicative of internal battery temperature; and
a controller for controlling heating of the battery back up to its effective battery temperature when the internal battery temperature falls below a predetermined level, so that the battery remains ready to operate effectively when the vehicle is returned to operation. - View Dependent Claims (17, 18, 19, 20)
