Battery retrofit part two

These picture Harm took for us “on request” and are all taken from under the car looking up with the cover screen and battery removed.

Battery cavity. Bottom of picture is front side of the car. Note the orange HV power cable, black control cable, shiny pipes running from the A/C to the battery evaporator, black brake lines and the cutout on the right side where the HV cutoff will go into the cabin.

 

Other end of “the cavity. Notice the extra space for “the chimney”, the three holes for cooling air (middle for air going into the battery, others for outflow), same A/C and brake pipes and the bowden cables for the hand brakes.

 

Same area but taken a bit front-to-back. Here you can see the very flat air ducts going from the top and over “the chimney” to the fan/evaporator unit behind it. The coolant pipes hop over the chimney too.

 

Front side of the battery, showing the HV receptacle and the control receptacle. The former is connected to the actual battery through a beefy relay, current sensor, 275 amp fuse and the HV disconnect. The latter basically contains just a 12 volt bus to run the LBC computer inside the battery and the Electro CANbus.

 

Underside of the motor peeking from the front side of the car. It can be divided in three parts. Left side is electrical inlet (you can just see the slip ring connector) and the modest water cooling in/outlet. Middle is the actual motor. Right side is the 9.8 reduction gear and differential. Top shows some A/C pipes. Bottom shows the axles to the front wheels.
