After working on EVSE’s “Electric Vehicle Service Equipment” sometimes referred to as chargers for many years, I somehow have amassed a collection of charging cables that I thought were interesting enough to share.

Most EV drivers are somewhat familiar with the ubiquitous J1772-2009 Type‑1 connector that is used on many EVSE’s. It is capable of up to 19.2 kW (80 A @ 240 V) AC supply to the vehicles onboard AC to DC charger. Even it has seen some changes over it’s history such as the CCS Combo 1 connector which adds two additional pins for DC fast charging up to 350 kW.
Currently the NACS connector is quickly replacing the dominance of the J1772-2009 and CCS Combo 1 connectors.


Pictured above is my J1772 Rev. 2009 Yazaki plug prototype which is capable of 5.76 kW using a single phase 120/240 Volt AC supply at up to 24 Amps. It was the predecessor to the J1772-2009 Type 1 connector and featured “finger-safe, touch-proof contacts,” designed to last for over 10,000 insertion/removal cycles.


Before the J1772-2009 there was the SAE J1772-2001 rectangular Avcon connector which could deliver up to 6.6 kW of AC power to the on-board EV charger. Earlier versions included two DC contacts for Level 3 charging, but those contacts were dropped in the SAE 2001 version.
My 1996 prototype connector came with a AWG 16–4 cable which limits it’s power to around 3.12 kW.




Before the conductive charge EVSE’s there were inductive charging EVSE’s such as the Magne Charge which used inductive paddles and vehicle inlet slots. There is no direct electrical connection between the paddle and the EV inlet slot. Instead the pair forms the two halves of an electrical transformer and operates at a frequency of 130 to 360 kHz AC similar to a high frequency switch mode power supply.


I also have a original new Magne Charge housing, but it is missing most of the internal electronics except for the GFCI module, and display. My guess it that the internals were scavenged to repair a failed installed system.
If anyone has the internal electronics, working or not that they can spare. I would like to put together a complete system someday.
