Global automotive supplier Marelli has introduced a wireless battery management system for EVs that will be available beginning in the second quarter of 2022.
The Wireless Battery Management System (wBMS) offers wireless communication between the batteries and the control unit. The company says, “Compared to previous wired distributed solutions, the new wBMS reduces the wiring harness by 90% and simplifies the battery cell construction and installation.”
The wBMS is available with software that estimates the states of charge, health and power for each battery cell.
“Marelli designed both the wBMS and the Wired BMS with identical base architectures, supported by two different ways of communication and interfaces,” said Head of Power Electronics Technology at Marelli’s Vehicle Electrification Division Dr. Razvan Panati. “In that way our technology can be applied across multiple vehicle platforms with minimal change. This flexibility of the solution guarantees significant reduction in engineering costs and allows Marelli to make this high-end technology affordable for the mass market.”
