LOTUS, WIRELESS BATTERY MANAGEMENT SYSTEMS, AND THE FUTURE OF HIGH PERFORMANCE EVS
"Industries around the world are pivoting toward new technologies that protect the health of the planet. Electric vehicles, and the push for clean energy, are rapidly becoming part of our daily lives. We are honored to collaborate with Lotus to deliver our groundbreaking ADI production wireless BMS for their iconic vehicle lineup.”

wBMS: A FULLY INTEGRATED SYSTEM
ADI’s wBMS is composed of 40 hardware components. The full system is tied together with turnkey software, an end-to-end ultra-robust and secure network, and complete battery cell monitor software, including application and safety.
Components include the ADBMS6815, which accurately measures the state of charge of the battery cells and pack; the LT8618, a compact, high speed, high efficiency synchronous monolithic step-down switching regulator for power management; and the ADRF8800, which ensures robust and reliable wireless connectivity.
“Our latest wBMS products also support battery recycling and reuse in energy storage systems to support the circular economy. Offerings from our competitors might bundle hardware, but you wouldn’t have software tying it all together. With ADI wBMS, there is no software for the customer to write, enabling them to focus on other aspects of vehicle design.”

LIGHTWEIGHT VEHICLES ARE HEAVYWEIGHT CONTENDERS
Innovative engineering and breakthrough technologies enable Lotus to realize outstanding performance through light weight. Reducing the car’s mass is the most effective means of achieving a true connection between driver, car, and road. “Lotus’s primary focus during the ADI engagement was removing the wires and keep everything lightweight while maintaining optimal BMS performance,” said Shane O’Mahony.
Eliminating the electric battery pack’s wiring harness takes weight out of the vehicle, as you are removing wires and connectors. Battery pack unharnessing also improves reliability as the associated cables and connectors are notoriously points of failure for the system. An added benefit—an untethered battery pack is better suited for design flexibility and scalability.
“Weight is a killer of high performance sports cars.”

“Wireless BMS enables state of health measurement and robotic assembly and disassembly of battery packs to ensure insufficient battery cells can be identified and removed, and the pack repaired efficiently.”
