How are cell failures handled in large lithium battery packs?
In a large battery pack of lithium-based cells for an electric vehicle or grid storage system, how are failed cells handled? Answers to another question indicate these cells are usually hardwired in parallel blocks (which are then connected in series and balanced) so that resistance isn''t added in the path of high current. ...
Ultimate Guide: Golf Cart Battery Troubleshooting and Maintenance
Corrosion happens when hydrogen gases, released from your battery, mix with other chemicals and gasses in the atmosphere, and then bond to the metals of cables, terminals, and battery posts. The corrosion looks like fuzzy blue/green stuff, similar to a mold colony that had a crazy lit party on your battery.
