The battery management system (BMS) closely monitors and manages the charging and health status of multiple battery strings. For large high-voltage battery packs (such as in electric vehicles), accurate monitoring of each battery cell and the entire battery pack parameters is crucial to ensuring maximum usable capacity and safe and reliable operation. The quality of the battery management system directly affects the mileage that an EV can travel per charge. A high-quality battery management system can maximize the overall battery life, thereby reducing the cost of ownership.



Service life and battery management system

With the increasing popularity of electric vehicles, the industry has put forward increasingly high performance requirements for technology providers. Our battery management system can provide first-class voltage and current measurements, driving innovation in the EV field.

High voltage battery stack management

Combining accurate battery voltage measurement via LTC6810, LTC6811, and LTC6813 with synchronous stack voltage and current measurement via LTC2949, it is integrated on a single isoSPI bus with fault-tolerant communication capabilities.



Vehicle Range and Charge Capacity

Vehicle range and charging capacity



Whether the battery is charging or discharging, ADI's excellent BMS can measure accuracy, allowing the vehicle to charge more fully and discharge more thoroughly. In short, a BMS maximizes usable capacity, which is key to maximizing vehicle range, cost, weight, and size.




Vehicle Safety and Reliability

Vehicle safety and reliability

Overcharging and over discharging can lead to battery damage, resulting in battery ignition, reduced capacity, or shortened service life. ADI's BMS devices can provide relevant measurement information to ensure that each battery operates within a limited operating range, thereby addressing safety and reliability issues.
