KDPOF – leading supplier for automotive gigabit connectivity over POF (Plastic Optical Fiber) – now provide their plastic optical fiber connections for battery management systems (BMS) in vehicles. “Electric and hybrid power trains present different voltage domains with large level differences, such as the ECU domain with 12 Volts, the actuators domain with 48 Volts, and the electric power domain with 400 Volts,” explained Carlos Pardo, CEO and Co-founder of KDPOF. “The galvanic isolation between these domains is a must due to ground parasitic resistance and potential shorts between voltage domains.” Optical connections with POF provide the optimal means to achieve galvanic isolation, providing 100 Mbps Ethernet compatible solutions with enough margin to withstand the harsh automotive environment. In addition, they are easy to upgrade to 1000 Mbps when a higher data rate is required.
