Some years ago I worked on the then being developed batteries for the electric cars today. The vendor started testing early in development and so the EMC features could be designed in rather added on. They had a cable for status reporting, and one for DC power, in or out as needed. As Ken noted, the smarts too care of everything.

In my experience, these batteries control themselves and do not need an external interface to provide functionality, or control of charging or discharging or anything else. The internal circuitry senses current into or out of the battery, as well as charging potential, and if any of these or internal temperature exceeds limits, it shuts down.
