I like the Joule concept but it has a sticky point as all electric or hybrid vehicles do: PRICE

Here is a estimated price break down based on some of the details from this article:
http://www.itweb.co.za/index.php?op...-to-drive-in-2012&catid=69:business&Itemid=58

  • Joule base model : R240 000
  • Monthly battery leasing equating to about two tanks of fuel : R749 (50 litres 93 ULP * 7.49 * 2 tanks)
  • Cost to recharge batteries at home in Tshwane (74.2 cents/kWh): R326

Assumptions:
  • Distance traveled between JHB and PTA is 100km per day for 22 days per month
  • Average power consumption for 100km is 20kW for 1 hour = 20kWh
  • Charging efficiency of charger and battery is 100%

So the real operating cost fuel wise is R985 per month but with Eskom's tariff increases it could be closer to R1629 per month in 2-3 years time.
The repayments over 6 years with a 20% deposit, prime -0.5% and no balloon payment is going to be R4446 per month.
Add on at least R500 for insurance

Total cost at current electricity prices: R5931 per month
Total cost at R2.0 per kWh : R6575 per month


Maybe that's affordable for some people but my second hand car repayment plus fuel plus maintenance costs plus insurance is about half that amount.

Solar power would be very useful. Either to power the car directly or to replace Eskom's coal-powered power. But that's not really an option, is it? :(

Nice calcs, thanks. One thing our government MUST implement in order to help with the adoption of EVs (and general load "spreading" on the grid) is off peak electricity tariffs. If electricity was only arounfd 40c/kwh in 2010, say, between 20h00 and 05h00, it would save EV owners a lot of cash.
