Intelligent power management company Eaton has announced a partnership with Munich Electrification to develop and market a battery configuration switch (BCS) for EVs. The device enables 800-volt vehicles to charge via 400-volt chargers, offering increased charging flexibility for consumers.
The BCS is designed for automotive, light commercial, and UTV applications. It allows for the reduction of up to 12 components in a battery disconnect unit, simplifying the system and streamlining packaging and assembly. The device also minimizes contact resistance, potentially improving overall system efficiency.
“We’re leveraging our extensive background in developing electrified mobility solutions to launch this promising new technology in partnership with Munich Electrification, which specializes in developing cutting-edge battery management systems,” said Mark Schneider, president of Eaton’s eMobility division.
The BCS incorporates safety features, including a mechanical interlock to prevent pack short circuits due to crashes, software bugs, or contactor malfunctions. It can maintain stable conditions when the electronic control unit loses power and provides resilience against low voltage faults.
Uwe Wiedeman, managing director of Munich Electrification, commented on the collaboration: “Munich Electrification’s legacy of innovation in the EV battery industry combined with Eaton’s expertise in electrical switching and automotive manufacturing is helping us to solve our customers’ biggest challenges together.”
Eaton, a company focused on intelligent power management, operates across various markets including data centers, utilities, and aerospace. The company aims to accelerate the transition to renewable energy sources and address global power management challenges.
The partnership between Eaton and Munich Electrification represents a step forward in EV charging technology, potentially expanding the network of compatible charging stations for 800-volt vehicles.
