The Charging System
There are several components to the charging an electric auto. The charging components for Maggie are found in the trunk and on the wall of my shop for the external "charging system" The charging takes place via three systems whose names can be confusing:
The Charging Port
The Charge Controller
The Charger
The Battery Management Systems (BMS)
The Batteries.
I'll describe them in reverse order.

The Batteries: In the prior page, we discussed loading the Tesla S batteries. The objective of charging of course is the batteries.

The two boxes shown at the bottom left of the picture are the BMSC and BMSS, the Battery Management System Controller and the Secondary to manage the second box. Both of these controllers re mounted inside the battery boxes.

It's amazing to me that the EV Charge Controller, "EVCC", is just a tiny box. You can see it's size on the above picture of the trunk.

The charger is larger. It takes AC current trough the J1772 plug and converts it to DC to actually change the batteries. The electrical flow is through cables running the the from of the car, and to the connection to the batteries in the contactor box
