Update on New US/Canadian Battery Management System Standard

Session: Rapid-Fire Introductions by Poster PresentersDate: Wednesday, October 16, 2019 / 8:50AM - 9:20AM PDTTags: Poster / Deployment and Field Experience

CSA Group is currently developing a bi-national US and Canadian standard for the certification of battery management systems (BMS), CSA C22.2 No. 340. A small sub-committee of industry experts is currently working with CSA Group to complete a seed document which will form the basis of the standard and go to the full Technical Committee of industry experts for further development. The standard will be in development with the Technical Committee and approaching the public review stage at the time of the Exchange conference, with publication expected in 2020.

This poster/presentation will provide a detailed, timely update on the contents, process, and timeline for publishing the standard. Presentation at the Exchange conference will help the committee to ensure that all stakeholders in the ES industry have a chance to be aware of these developments in the new standards landscape. Feedback from the conference will help the committee in their efforts to finalize the draft for public review.

BMS play an important role in the safe and high-performing integration of many battery-containing devices, including energy storage systems. The new standard will enable a consistent, standardized approach for BMS safety compliance evaluation which does not currently exist.

The standard covers BMS in all applications including stationary batteries (e.g. local energy storage, smart grids, auxiliary power systems), batteries used to power mobility applications (e.g. electric vehicles, rail transport, aeronautics), and appliances and machinery (e.g. tools, kitchen appliances, manufacturing lines) used in consumer/ residential, commercial, and industrial settings. The latest requirements in the draft standard will be presented, and include topics such as: overcharge, overdischarge, overvoltage, cell balancing, device disconnect, short circuit, thermal management, and functional safety of the electronic controls and software.
