What is a Battery Management System?

Topics Covered:
Purpose of a BMS
BMS Inputs
BMS Outputs
Current Sensors
BMS System Diagram
BMS Communication

Erik Stafl, president of Stafl Systems, explains two primary purposes of a battery management system for a lithium-ion battery pack: providing safe and reliable operation. The Battery Management System takes a number of inputs, including voltage, temperatures, and current among other inputs. The BMS then runs algorithms to create a series of outputs including state of charge (the fuel gauge), the state of health, the safe operating envelope ™, and any faults the battery pack may have.

Erik then describes how the BMS is used in a multi-cell application, using a system diagram.

이장수 : 좋은 정보 공유 감사드립니다.
Adam : 저는 전고체 배터리 전공자입니다
영상 잘 챙겨보고 있습니다ㅎ
이원형 : 좋은 정보 공유 감사드려요!
Hsi : 차량용 bms엔지니어 라는 직군이 존재할까요? 전자공학과 학생인데 이쪽분야로 가고싶습니다. 한국이나 미국이나 학부수준에서는 못배우는 분야같아서 미국이나 한국에서 석서를 밟고싶습니다
Taeyeong Kwon : 전기차는 과전류가 흐르거나 유사시 퓨즈가 작동하는게 차단기가 내려가는식으로 차단되나요 아니면 내연기관차처럼 퓨즈가 끊어지나요??

Dipak Joshi : Very detailed explanation which will understandable by all level of audience. This video is nothing but a jackpot who are looking for fastrack revison before attending a electric vehicle related job interview.
Thank you for adding this vital content.
Fast Iron : Funny he is reading form https://www.electronicdesign.com/power-management/article/21800666/a-look-inside-batterymanagement-systems#:~:text=A%20battery%2Dmanagement%20system%20(BMS,of%20BMS%20ICs%20are%20available.
pyladian : Thank you for this informative and well explained video.I have very little knowledge of electronics,so your use of simple language helped me deepen my understanding,well done!
Jeff Sit : When the battery pack is not on a load (not connecting to any appliance or device) or even charging, will the BMS be still working automatically to balance the cells ?
Lani swamy : Excellant well made presentation. Keep it up.
