Accelerate xEV design
Converting the high-voltage xEV battery to 48V or 12V

The challenge of high-density power conversion from 400V and 800V EV batteries

Primary EV batteries are increasing in voltage up to 400V and 800V, putting tremendous strain on traditional solutions to efficiently deliver power to 12V and 48V loads without taking up valuable weight and space. And those 12V and 48V batteries are vestiges that cannot be replaced by the primary battery because those traditional solutions cannot replicate the fast response time of batteries. Eliminating those batteries would not only save additional space and weight, making EVs lighter, faster, and more energy-efficient, but in the case of the 12V lead-acid battery, it would also remove toxic waste from the environment.

The Power Delivery Network

The BCM6135 modules enable standard 800V and 400V batteries to supply 48V power delivery networks reducing weight and space consumption. The BCM6135 provides bidirectional power conversion and fast transient response, eliminating intermediate energy storage at 48V. The BCM6135 can virtualize the HV battery to look like a 48V battery within the system without the space and weight associated with a physical 48V battery.
