Did you know?

The global EV Battery Management System (BMS) market was valued at approximately $1.42 billion in 2021 and is projected to grow at a CAGR of 17.2%, reaching$5.67 billion by 2027?

Efficient BMS are crucial for maintaining battery health, with studies indicating that EV batteries retain about 90% of their capacity after 100,000 km and 87% after 300,000 km, thanks to advanced BMS technologies.

But wait, there’s more! The integration of wireless Battery Management Systems (wBMS) can reduce wiring harnesses by up to 90%, leading to more efficient vehicle designs and reduced manufacturing complexity.

Unlock the full potential of your EV batteries with Embitel’s cutting-edge BMS solutions! Our expertise in developing customizable and robust BMS ensures optimal battery performance, safety, and longer life cycles, empowering you to lead the EV market.

Embitel’s Battery Management System Service Offerings

voltage and current Protection — Voltage and Current Protection

Our EV Battery Management System detects Over-Voltage and Under-Voltage by actively monitoringthe voltage of each cell and the battery pack. The battery pack is protected from overcharging and over discharge via overcurrent monitoring

Temperature Monitoring

Each cell’s temperature is monitored to maintain excellent performance and efficiency while protecting the battery pack from overheating.

cell Monitoring — Cell Monitoring / Balancing

To avoid an imbalance in the charge levels of the individual cells that make up a battery, it is ensured that they are operated within their safe operating range. It monitors and responds to the State of Health (SoH), State of Charge (SoC), and Depth of Discharge (DoD).

Diagnostics and Relay Control

Relay control and diagnostics employ multiple-point voltage monitoring, fault monitoring, and continuous parameter monitoring to guarantee safe operation and dependable battery performance. Through the orderly execution of relay activities, the pre-charge function is integrated.

Optimized Charging and Discharging

High efficiency and cutting-edge features are offered by **switch-mode power supplies (SMPS)** for quicker and cooler charging.

Isolated CAN Communication

To improve efficiency and save costs, daisy chain communication between CAN-based LCUs is used in the communication.Galvanically isolated CAN circuits provide dependable communication.

FAQs

What are the various types of Battery Management Systems for Electric Vehicles?

Ans. There are two primary categories of Battery Management Systems for Electric Vehicles. The first type is a centralized BMS, which employs a single control unit to oversee all battery cells within the system. The second type is a distributed BMS, which utilizes multiple control units to manage the battery cells in the system.

Which software is utilized for automotive Battery Management Systems?

Ans. An automotive Battery management system plays a crucial role in modern Electric Vehicles. Embitel provides an integrated platform for the development, testing, and verification of these advanced systems. This platform offers substantial advantages in terms of time, cost, and quality for BMS development teams.

What does a battery management service entail?

Ans. Battery Management System refers to technology dedicated to monitoring a battery pack. This pack comprises a configuration of battery cells organized electrically in a row x column matrix. Battery Management service enables the delivery of a targeted range of voltage and current for a specific duration, taking into account anticipated load scenarios.

Does automotive Battery Management Systems always handle battery charging?

Ans. Embitel comes with a solution of automotive Battery Management System that oversees the recharging process of the battery by directing recovered energy (such as from regenerative braking) back into the battery pack. Typically, the battery pack consists of multiple battery modules, each comprising numerous cells.

What is the role of a typical Battery Management System designed for Electric Vehicles?

Ans. The primary function of a Battery Management System for Electric Vehicles is to ensure that the battery operates within safe parameters concerning voltage, current, and temperature during charging, discharging, and, in certain situations, during open circuit conditions.

Why is BMS utilized for lithium-ion batteries?

Ans. A Battery Management System is indispensable in a Lithium-Ion battery system. This device facilitates real-time control of each battery cell, communicates with external devices, manages state of charge (SOC) calculations, and measures temperature and voltage, among other functions.
