Abstract
Systems and methods monitoring battery bus bars are disclosed. In one example, positive temperature coefficient thermistors are coupled to battery bus bars. The systems and method may reduce the cost and complexity of battery bus bar monitoring.
Claims20
A method for monitoring status of battery bus bars, comprising:
- adjusting battery pack operation in response to a change in state of output of any of a plurality of temperatures sensors mechanically coupled at different locations to one or more battery bus bars, the plurality of temperature sensors in a daisy-chain configuration.
A method for monitoring status of battery bus bars, comprising:
- coupling a plurality of temperature sensors to a plurality of battery bus bars;
- electrically coupling said plurality of temperature sensors in a daisy-chain configuration;
- electrically coupling said plurality of temperature sensors to a digital input of a controller;
- and
- adjusting battery pack operation in response to a change in state of said digital input.
