Overview
The Tesla GEN1 charger is a single/three phase 10kW AC charger that was fitted in the Model S from 2012 through late 2013, when it was replaced with GEN2. GEN1 models are easy to identify, with the word "TESLA" stamped on the metalwork; the GEN2 charger lacks the Tesla identifier stamped on the metalwork.
One (or optionally two, in a Master/Slave configuration) GEN1 chargers are installed beneath the rear seats in the Model S for AC charging. If two are fitted, both are identical hardware, though the firmware differs.
The charger is made up of three 3.3 kw modules, each sitting on a liquid cooling plate. This assembly enables both single and multi phase AC charging.
The GEN1 chargers are considered to be more trouble-prone than the later units, and are not as popular for use in EV conversions or ground-up builds, but are used in many OEM installations that continue to need servicing. Examples of OEM installs include the 2012-13 Tesla Model S, 2012-14 Toyota RAV4 EV[1], and 2014-17 MB B250e[2]. As far as is known, these are identical from a hardware perspective, but the firmware does differ and is not interchangeable between installations.

Common Issues
- The Tesla chargers are very sensitive to grounding. The case MUST be connected to vehicle 12v ground AND evse earth/ground when charging. [1]
