I have been driving MR02EV for about 4 years using a battery pack consisting of 56 Thundersky lithium-ion cells totalling 201.6 Volts and 12kWwh; it has served me pretty well. Initially my driving was in city traffic 0 – 60 kph so performance was not an issue and the 70 kilometre range was more than adequate.
Because Electric Vehicles do not have an internal combustion engine there is no traditional vacuum source to supply the brake booster, so a vacuum pump and vacuum flask is needed. In fact it is mandatory for registration of the vehicle.
The modified Corolla gearbox which is now a 2 speed was finally installed into MR02EV (see earlier posts for details on the modifications).
MR02EV has been a registered road going vehicle for 3 years and covered about 12,000 kilometers in that time, mostly through commuting to work and running around town. It’s a fun car to drive. But right from day one the gearbox has been plagued with problems, excessive noise and excessive backlash, which has just gotten worse over time.
I have a Degree in Electrical Engineering from the University of Technology Sydney and am employed in Broadcast Television Industry. My hobby is the (continuing) modification of MR02EV. I am also the National Treasurer of the Australian Electric Vehicle Association.
