Fully Electric Rimac Hypercar to Use Analog Devices’ Precision Battery Management System

Analog Devices’ precision battery management system integrated circuits are to be used for the Rimac C_Two fully electric hypercar capable of speeds of up to 258 miles per hour. 

The Rimac C_Two electric hypercar has 1,914 horsepower and can accelerate from 0-60 mph in 1.85 seconds. To support this high-performance, Zagreb, Croatia-based Rimac intends to use Analog Devices’ (ADI) precision battery management system (BMS) integrated circuits (IC). The BMS acts as the brains behind battery packs by managing the output, charging and discharging as well as providing precision measurements during a vehicle’s operation. A BMS also provides vital safeguards to protect the battery from damage. ADI’s IC technology will provide Rimac’s BMS with the ability to extract maximum energy and capacity out of its batteries by calculating reliable state of charge and other battery parameters at any given time.

“High-performance electric vehicles require high precision electronics,” said Analog Devices’ automotive electrification and infotainment vice president, Patrick Morgan. “Precision accuracy directly translates to maximizing battery capacity and range with fast charging time. We are pleased to support Rimac with our precision battery management ICs for its leading-edge electric vehicle systems with the goal of achieving some of the best performance in the world.”

Better Batteries for Electric Cars

A battery pack consists of groups of individual battery cells that work together to deliver maximum power output to a car. If the cells go out of balance, the cells can become stressed leading to premature charge termination and a reduction in the battery’s overall lifetime. ADI’s battery management ICs deliver highly accurate measurements, resulting in safer vehicle operation and maximizing vehicle range per charge.

“Our application of BMS is among the most demanding in the world, requiring the highest accuracy, massive current and voltage draws over very short time scales, and rapid dynamic adjustment within the battery management control system,” said Rimac founder and chief executive officer, Mate Rimac. The company, headquartered on the outskirts of Zagreb, Croatia, employs around 600 people and develops and manufactures electrification systems for many global automotive companies. Rimac added: “We have decided to adopt the Analog Devices portfolio of battery management [integrated circuits] ICs across our complete product line of battery management systems. ADI’s ICs are an integral part of our in-house developed BMS that we are using in our own vehicles, but also for many global car brands.” 

Analog Devices offers a broad portfolio of precision battery management ICs serving multiple cell configurations and battery types across a wide range of applications in multiple industries. In addition to electric vehicle battery management systems, applications include on-board chargers, high power electrical storage systems, backup battery systems, and high voltage data acquisition systems.
