Determining Status of High Voltage Battery for Emergency Responders
First Claim
1. A method for verifying a status of an electric vehicle for approach by emergency personnel after a collision involving the vehicle, the vehicle having one or more high voltage batteries to supply electrical power to a vehicle drive system, the method comprising:
- collecting a value of each of one or more battery parameters via a battery controller mounted to the battery, wherein the battery controller includes a wireless link capability;
transmitting the collected values from the battery controller to a system controller;
deriving a vehicle status based on the collected values at the system controller; and
broadcasting the vehicle status from the system controller for receipt by an emergency responder communication device.

Abstract
The described method and system provide an early notification to emergency responders regarding a non-nominal condition associated with a vehicle involved in a collision. The system provides a short range wireless system controller in communication with a battery controller. The short range wireless system controller is further in communication with a communications device associated with an emergency responder via broadcast over a short range wireless RF network. If battery physical parameters indicate that the battery has suffered damage rendering the vehicle inoperable, this battery damage information is broadcast over the short range wireless RF network to the communications device associated with the emergency responder. In this way, the emergency responder can quickly aid incident victims without time lost in determining whether or not the high voltage vehicle battery is in a nominal state after the crash.

17. A system for apprising one or more emergency responders of a status of an electric vehicle after a collision involving the vehicle, the vehicle having one or more high voltage batteries to supply electrical power to a vehicle drive system, the system comprising:
-
a battery controller mounted to the battery configured to collect a value of each of one or more battery parameters, and having a short range wireless link capability; and an in-vehicle system controller configured to collect data from the battery controller via the wireless link capability of the battery controller and to derive a status of the vehicle based on the collected data, the in-vehicle system controller further comprising a wireless link for transmitting the status of the vehicle to an emergency responder communication device. - View Dependent Claims (18, 19, 20)
