battery protection

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), calculating secondary data, reporting that data, controlling its environment, authenticating or balancing it.
Protection circuit module (PCM) is a simpler alternative to BMS.
A battery pack built together with a BMS with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a smart battery charger.

    12V power socket - how to protect the battery

    I have a electric tyre air pump that plugs into the 12V socket. On my ICE car I have to have the engine running so the battery doesn't go flat. How does it work on these EVs ? If I power on the car will it draw power from the main battery and protect the 12V battery ? Bit of a noob question...
