eTrixie — part two

The conversion of this VW Beetle, to electric power, is underway. In part two of the process there’s talk of torque, power and brakes.

Going and Stopping

Having decided to convert our VW Beetle (Trixie) to 100% electric, there are a number of changes underway.

Trixie currently has a 1600cc (roughly 40 horsepower) engine. The new electric motor is an HPEVS AC-50 which produces slightly more power than the petrol engine, but with instant torque.

The motor is paired with a Curtis AC Motor Controller which, among other things, supports regenerative braking. This will be great for Wellington’s hills.

The fuel tank will be replaced with 37 lithium iron phosphate cells, making a 122V battery and delivering about 22 KWh of power. This will give us about a 150km driving range per charge.

Before starting the conversion I decided to update the front brakes from drum to discs. While I still had the car running with the petrol engine it was much easier to do the brake change and then fully test the outcome. EMPI Disc kits are awesome; they include a new master brake cylinder to match the new disc brakes — here is a picture of the outcome:
