…and didn’t really want to know.
This is the 22kW charger box found in the 451 ED. Apparently it was the 1st 22kW in an electric car. It’s bigger than you think too. It’s nearly half a metre wide.
It has 2 water connections for cooling and 4 electrical connections.
The coolant connectors are Normaquick PS3 NW12.
Straight connector – 07028009012
Right angled connector – 07028008012
The coolant inlet is on the same side as the red connector. The coolant outlet is on the opposite side.

Name Plate Info
On the underside of the unit is an information plate. 1 section of the plate is the important part number.
Original Model D01
This version had issues with faulty power capacitors. They burst and the charger stops working. You may sometimes be “lucky” and the 3.7kW charging may still work.
Updated Model D02
This had updated capacitors and an updated main board. These seem to be OK.
Request
If anyone has a failed one of these that they don’t want. I’d be interested in having it for inspection.
