The Bluetooth SIG released version 5.4 of the Bluetooth Core Specification last year. This latest version introduces a number of exciting features that will unlock the potential of certain high-volume applications. An application that is expected to benefit significantly from this new release is battery management systems (BMS) for electric vehiclesBluetooth BMS.

Typically, the common BMS uses a wired connection to communicate with other systems in the vehicle. The weight and wiring design complexity increases significantly with all the cells and modules in a battery pack connected to the central BMS through multiple wires and connectors. Wireless technology becomes critical as electric vehicles become increasingly complex, and the need to increase efficiency, reduce costs, and improve the accuracy of battery monitoring and control. Bluetooth BMS emerges as a game-changer, empowering users with unprecedented control, efficiency, and convenience.

What is a Bluetooth BMS?

A Battery Management System (BMS) is a sophisticated electronic system designed to monitor and regulate the performance of rechargeable battery packs. Wireless BMS considers a variety of wireless solutions. Some of these are proprietary solutions, customized for wireless BMS use cases. However, there are significant advantages to using a standard solution such as Bluetooth, especially with support for version 5.4 of the Bluetooth Core Specification.

The benefits of incorporating Bluetooth into BMS are manifold:

High throughput: Bluetooth delivers data rates in excess of 1 megabit per second. As a result, Bluetooth can transfer more data in less time, meeting the requirements of BMSs that need to transfer large amounts of data to a central processing unit and scale with the number of battery modules. Higher data rates also mean lower latency, which is critical for safety.

Synchronized low latency and reliable connectivity: Currently, battery packs typically contain fewer than ten cell modules. However, this may increase to dozens in the future. Each module needs to report data to the central unit efficiently and quickly. Damaged battery cells need to be diagnosed at a moment’s notice to avoid dangerous consequences such as overheating. A Bluetooth-based wireless BMS consists of several battery modules that communicate with a central unit. Its Bluetooth technology provides reliable data transmission even in noisy environments.

Secure Connection: Bluetooth technology provides secure communication through encryption and authentication, preventing unauthorized access and securing device data. Prior to version 5.4 of the Bluetooth specification, it was not possible to encrypt broadcast data. This is now possible with the new “Encrypted Advertisement Data” feature, which is a great complement to PAwR for more secure communication.

Low cost: Bluetooth LE chips from major suppliers are shipped in very high volumes across a wide range of applications, with low selling prices due to economies of scale and highly amortized development costs.

How Does a Bluetooth BMS Work?

A Bluetooth BMS operates on a principle of continuous communication and data exchange. The system consists of several key components:

-Battery Pack: The heart of the system, comprising multiple cells or modules.
-BMS Controller: An intelligent control unit that monitors and regulates the battery pack’s performance.
-Bluetooth Module: Enables wireless communication between the BMS controller and external devices.
-Mobile App or Software Interface: Provides a user-friendly platform for monitoring, configuration, and control.

The BMS controller continuously monitors various battery parameters, such as voltage, temperature, and current flow, using specialized sensors. This data is then transmitted wirelessly via Bluetooth to the connected mobile app or software interface, allowing users to access real-time information and make necessary adjustments. Through the intuitive interface, users can remotely configure settings, initiate charging or discharging cycles, and even receive alerts or notifications in case of potential issues or safety concerns.
