Battery Management Systems (BMS)

The battery market continues to be driven by a demand for longer range vehicles, improved functional safety, and decreased charge times and cost. Analog Devices’ lithium ion and lead acid battery management systems target demands directly and provide solutions that alleviate market concerns.

Unlike a single energy storage element, such as a fuel tank, an EV battery pack consists of hundreds or thousands of individual battery cells working together. ADI’s battery management systems are directly connected to each cell, providing accurate cell measurement from the time the pack is manufactured to its retirement. Irrespective of how they are connected, our extensive portfolio of battery management system devices provides the flexibility to support virtually all battery system architectures with optimized and efficient design.

Longevity and the Battery Management System

As electric vehicles continue to grow in popularity, the industry is demanding increased performance from technology providers. Our battery management systems deliver best-in-class voltage and current measurement to drive innovation in EVs.

Longevity and the Battery Management System

High Voltage Battery Stack Management

Combining Precision Cell Voltage Measurements via LTC6810, LTC6811 and LTC6813 with Synchronous Stack Voltage and Current Measurements via LTC2949 on a Single isoSPI Bus with Fault Tolerant Communication.

Vehicle Range and Charge Capacity

Vehicle Range and Charge Capacity

ADI’s outstanding BMS measures accuracy whether the cells are charging or discharging, which allows the vehicle to charge more fully and discharge more completely. Simply put, BMS maximizes the usable capacity—key to maximizing vehicle range, cost, weight, and size.

Vehicle Safety and Reliability

Vehicle Safety and Reliability

Overcharging and over-discharging cells can lead to damage, resulting in battery fires, capacity reduction or reduced lifetime.Analog Devices’ BMS devices address safety and reliability concerns by providing measurements that ensure each cell is functioning within a constrained operating range.
