Bosch and Mitsubishi launch a battery service joint venture
Bosch and Mitsubishi Corporation bring their battery expertise together in BMB. The joint venture turns battery data into decisions on health, charging and value.

Batteries have become the most valuable part of an electric vehicle and the biggest investment in a storage site. Yet their owners rarely know what they really hold, how they should be charged or what they will be worth in a few years.
That is the gap Bosch MC Battery Service Innovations, BMB for short, was set up to close. The joint venture between Bosch and Mitsubishi Corporation is a data company. For every battery, it measures the real capacity of the pack, how it should be charged and what it is worth. It then makes those insights usable for the businesses that run them.
“The battery is where most of the value sits, and it is the part nobody can see inside. That is what we are here to change.”
Built for the assets that carry the energy transition
BMB works across four types of assets: grid scale batteries, the packs inside electric buses, trucks and vans, the chargers that fill them, and battery swap stations. The software is hardware agnostic. Whatever the make of battery or vehicle, BMB reads its operating data. It turns that data into an SoH figure, a charging plan or a forecast.
Who we work with
Our first customers are leasing and remarketing companies, grid scale storage operators, fleet charging and energy service providers and logistics companies. Each of them carries battery risk on its own balance sheet. Each of them needs a number it can trust, rather than the manufacturer’s estimate.
In the coming months, BMB will share more about the platform and the teams in Germany and Japan. It will also share what it learns from the batteries it measures every day.
