Abstract

A plurality of types of heat-treatment requests are described in a signal in a single byte.

Claims

1. A method of transmitting a signal describing a temperature-control request for a battery, wherein the signal is a single byte configured to describe eight types of the temperature-control request, the single byte comprising at least the following temperature-control requests:

slight heating, intermediate heating and strong heating;

slight cooling, intermediate cooling and strong cooling;

presence of a fault; and

flushing the battery with a fluid for homogenizing a temperature distribution of the battery.

2. The method of claim 1, wherein the battery is a traction battery.

3. The method of claim 1, wherein the signal is transmitted as a message on a bus architecture.

4. The method of claim 1, wherein the signal is transmitted as a message on a CAN bus.

5. A control device of a motor vehicle programmed to generate and/or evaluate a signal, wherein the signal is a single byte configured to describe eight types of a temperature-control request for a battery of the motor vehicle, wherein the types of the temperature-control request comprise:

slight heating, intermediate heating and strong heating;

slight cooling, intermediate cooling and strong cooling;

presence of a fault; and

flushing the battery with a fluid for homogenizing a temperature distribution of the battery.

6. The control device of claim 5, wherein the battery is a traction battery.

7. The control device of claim 5, comprising a first control device for battery management and a second control device for load management.
