Bosch new EV battery management system reduces maintenance costs

Electric cars have a long way to go, whether security, dynamic performance, mileage, must be further improved. At present, Bosch and the Carlsruhe Institute of Technology (KIT) and other colleges and institutions conduct a research project that spent 4.3 million euros.

Important research content is to improve the battery performance of electric vehicles and hybrid vehicles, and develop intelligent battery management systems. The basic principle of this technology is to use the path to exchange data and control signals to transmit data in the battery. Germany's Federal Education and Research Department will invest 2.

5 million euros of research funds from now on May 2016 to invest 2.5 million euros from projects "INTELIGENTABUSCONCENECTSFORLITHYBRIDVEHICLES). Intlilon project research object is a lithium ion battery.

The research direction will start from the power line communication system in the battery, more efficiently control and monitor the battery cell (monitor / control battery unit up to 100) in the battery pack. Once this power line system is mature, it will save a large number of cables used to transmit data in the traditional battery system, thereby reducing the cost of battery management systems. Bosch is responsible for Dr.

JenStrobel, researcher, said that the system can make separate monitoring and control of each battery unit. If there is a problem in a single lithium ion battery cell, for example, the work efficiency is lowered, only the single battery unit can be replaced, there is no need to replace the entire battery module. Largely reduce lithium-ion battery maintenance costs.
