Endurance buys Ion Energy's battery management system unit for $40 million

Bengaluru: , one of India’s largest automotive component makers, has bought the battery management system unit of energy tech startup Ion Energy for $40 million in an all-cash deal.

Endurance will buy 51% of Maxwell Energy Systems, a subsidiary of Mumbai-based Ion Energy, for $17.5 million to begin with. The remaining 49% will be bought in phases over the next five years, Ion energy said in a statement.

The investment will be a combination of both primary and secondary investments, the company said. In secondary investments, the proceeds go to existing investors who sell shares and not to the company itself.

After the acquisition, Maxwell will increase its R&D team to more than 250 engineers and launch new products for electric vehicles and energy storage systems.

The battery management system is an electronic system that monitors a battery’s state of charge and its health to ensure that it is protected. For Endurance, which supplies components to some of the biggest automotive companies like
