Abstract

A vehicle system that communicates temperature information of a high voltage battery system of an electrified vehicle includes at least one temperature sensor, a controller, and a human machine interface (HMI). The at least one temperature sensor is disposed on at least one battery module of the high voltage battery system. The at least one temperature sensor is configured to sense a temperature of the at least one battery module. The controller receives the sensed temperature and determines a temperature profile of the high voltage battery system. The HMI is configured to convey temperature information of the high voltage battery system, wherein the controller communicates a signal to the HMI indicative of the temperature profile.

Claims (20)

1 . A vehicle system that communicates temperature information of a high voltage battery system of an electrified vehicle, the system comprising:

one or more temperature sensors disposed on one or more battery modules of the high voltage battery system, the one or more temperature sensors configured to sense a temperature of the one or more battery modules, wherein the one or more temperature sensors comprises a first temperature sensor and a second temperature sensor, wherein the one or more battery modules comprises a first battery module and a second battery module, wherein the first temperature sensor is disposed in the first battery module and the second temperature sensor is disposed in the second battery module;

a controller that receives the sensed temperatures and that determines a temperature profile of the high voltage battery system based on the sensed temperatures, the controller communicating a signal to the HMI indicative of the temperature profile; and

a human machine interface (HMI) provided on the electrified vehicle that receives the signal and that graphically displays a temperature gradient and an efficiency factor of the high voltage battery system based on the first and second sensed temperatures, wherein an efficiency factor less than 100% indicates that at least some of the one or more battery modules have a temperature that exceeds a threshold indicative of high temperature and negatively impacted performance.

2 . The vehicle system of claim 1 , wherein the one or more temperature sensors comprises ten temperature sensors, wherein a temperature sensor of the ten temperature sensors is disposed in a corresponding battery module of the one or more battery module.

3 . The vehicle system of claim 1 , wherein the temperature information comprises a first area indicative of a high temperature.

4 . The vehicle system of claim 3 , wherein the temperature information comprises a second area indicative of a first moderate temperature.

5 . The vehicle system of claim 4 , wherein the temperature information comprises a third area indicative of a second moderate temperature.

6 . The vehicle system of claim 5 , wherein the temperature information comprises a fourth area indicative of a low temperature.

7 . A method for displaying temperature information of a high voltage battery system of an electrified vehicle, the method comprising:

sensing, with a first temperature sensor disposed on a first battery module, a first temperature of the first battery module;

sensing, with a second temperature sensor disposed on a second battery module, a second temperature of the second battery module;

receiving, at a controller, the first and second temperatures;

determining, at the controller, a temperature profile of the high voltage battery system based on the first and second temperatures;

communicating, from the controller, to a human machine interface (HMI) the temperature profile; and

displaying, at the HMI, the temperature profile including a temperature gradient and an efficiency factor of the high voltage battery system based on at least the first and second temperature sensors, wherein an efficiency factor less than 100% indicates that at least some of the one or more battery modules have a temperature that exceeds a threshold indicative of high temperature and negatively impacted performance.

8 . The method of claim 7 , wherein the temperature profile comprises a first area indicative of a high temperature.

9 . The method of claim 8 , wherein the temperature profile comprises a second area indicative of a first moderate temperature.

10 . The method of claim 9 , wherein the temperature information comprises a third area indicative of a second moderate temperature.

11 . The method of claim 10 , wherein the temperature information comprises a fourth area indicative of a low temperature.
