Valmet Automotive is working on standardised, optimal communication and data transmissions from single-cells to the Battery Management System (BMS) and will present the first results at the 28th Aachen Motor Colloquium from 7-9 October.
An important aspect is the compatibility with current and future safety requirements for all-electric vehicles.
“Over the past decade, conventional wired BMS has served the electrification of vehicles well,” said Valmet Automotive SVP, Robert Hentschell
“But with the growing number of Battery Electric Vehicles (BEV), along with the demand for longer ranges and the use of larger batteries, the time has come to intensively consider the further development of the BMS.”
The solution provides real-time access to a variety of data not available on today’s systems.
Principle and data ensure increased measurement accuracy, reliability and safety of the battery system.

By GlobalDataIn a BMS based on single-cell monitoring, in which the data is transmitted independently via an NFC connection, Martin Lenz, director of Electrics/Electronics, sees promising solutions for the future.
“This technology has the potential on one hand to reduce the battery package by 10% and BMS cost by 25 %,” he said. “On the other hand it guarantees already cell monitoring in cell production and later on the traceability of each cell for the battery manufacturer and the pack user.”
Experts from Valmet Automotive will present the BMS based on single-cell monitoring at the 28th Aachen Vehicle and Engine Technology Colloquium, taking place from 7-9 October.
