How to Build A Battery Pack From 18650 Cells
Another critical job of a BMS is to make sure the battery pack is not put under too much stress. So, every BMS has a maximum current that, if achieved, will turn the battery pack off. Over-current protection applies to both charging and discharging the battery pack. Short Circuit Protection. A short circuit is equivalent to a 0 Ohm load.
Batteries Part 2
When a battery cell is open-circuited (i.e. no-load and R L = ∞Ω) and is not supplying current, the voltage across the terminals will be equal to E.When a load resistance, R L is connected across the cells terminals, the cell supplies a current I which causes a voltage drop across internal resistance R INT of the cell. ...
