Process and arrangement for monitoring and/or controlling charging of a modular battery, particularly in a battery powered vehicle
First Claim
1. A process for monitoring and/or controlling charging of a battery having power cables for supplying electric power to at least one power consuming component comprising:
- detecting at the battery measurement data relating to the condition of the battery; and
transmitting measurement data from the battery to an evaluation unit by applying coded alternating voltage signals representing measurement data to a battery power cable.

Abstract
In a process and arrangement for monitoring and/or controlling charging of a battery, particularly in a battery-powered vehicle, test data relevant to the monitoring are detected at the battery and sent to an evaluation unit through a power cable connecting the battery to at least one power consuming component. The evaluation unit is connected to the power cable and the test data are transmitted to the evaluation unit through the power cable using a coded alternating voltage. This eliminates the need for additional insulated signaling lines connecting the battery sensors to the evaluation unit and reduces the need for complicated wiring, particularly in batteries with modular construction as used in battery driven automobiles.
