Rimac Selects Analog Devices to Provide Precision Battery Management for Its High-Performance Electric Vehicles

“Rimac is a technological powerhouse in the field of high-performance electric vehicles. We develop and manufacture key electrification systems for many automotive companies around the world, while our own supercars set the bar higher for electric vehicle performance. The BMS we use is one of the most demanding applications in the world, requiring extremely high accuracy, large current and voltage changes in a very short time, and fast dynamic adjustments within the battery management control system. We decided to use Analog Devices’ portfolio of battery management ICs across our entire battery management system product line. ADI’s ICs are an essential component of our in-house developed BMS, which is used not only in our own vehicles but also in many global automotive brands. We have selected ADI’s products after comparing them in the market and have confirmed their ability to provide precise measurement accuracy and product reliability throughout the life cycle of the vehicle. We look forward to working with ADI in the future to implement high-performance BMS in our vehicles and battery packs,” said Mate Rimac, CEO of Rimac.

The Rimac C_Two is a pure electric supercar with a top speed of 412 km/h. The C_Two engine has 1,914 horsepower, 0-96 km/h acceleration time of 1.85 seconds, and 0-300 km/h acceleration time of 11.8 seconds. To support these high-performance outputs, the Rimac team designed and built outstanding underlying technologies such as electric drivetrains and battery packs.

BMS technology is the "brain" behind the battery pack, managing output, charging and discharging, and providing accurate measurements during vehicle operation. BMS also provides important protection measures to prevent battery damage. The battery pack is composed of multiple groups of independent battery cells that work seamlessly to provide the maximum power output for the car. If the battery cells lose balance, they will be affected by stress and cause charging to terminate prematurely, which will shorten the overall life of the battery. ADI's battery management IC provides highly accurate measurements, allowing vehicles to operate more safely and maximize the range after each charge.

“High-performance electric vehicles require highly accurate electronics. High precision directly translates into fast charging times and maximized battery capacity and range,” said Patrick Morgan, vice president of the Automotive Electrification and Infotainment Group at Analog Devices . “We are very pleased to support Rimac’s leading electric vehicle systems with our precision battery management ICs to achieve superior performance on a global scale.”
