I will try to answer as many questions as possible.
First, the charging station pictured above has since been improved to a better and advanced technology. The tech allows for momentous monitoring of power flow to the electric vehicles (EVs), remote monitoring of the charging process, authenticated usage of the charging station.
In Kenya, electricity is way cheaper than fuel. Say you own a Nissan Leaf 2012 model (EV) and compare it with a Toyota model (i choose this due to local popularity) and run both models for 150 kilometers daily. The EV with a 30kWh battery can give a little over 200 kilometers on a single charge. As such, it would cost the EV owner 30 units*22 shs (electricity price from kplc)=KES 660 to drive for the 150 kilometers. Now, for a modest Toyota, let us choose one with a consumption of 12 kilometers/liter. It will go on to consume 12.5 liters for the 150 kilometers. Currently, petrol cost is at KES 106.3 per liter. Doing the math, the Toyota will cost the driver a rough KES 1400. Now, KES 1400 for petrol vs KES 660 for electricity for the same is distance equals a 50% save for the driver.
The chargers for the EVs can be installed at a home, following set standards that guarantee safety for the users, at public places such as the prestigious malls scattered in Nairobi and the type of level of charging changes depending on the location. Eg a home owner may opt for a Level II AC charger and a mall may prefer a DC Charging station to charge EVs from 0 to 80% battery charge for just 30 minutes.
P.S- the Kenyan economy is starting to look real good for EVs, as the right policy advisers are underway to work on incentives for EV importers to the country. Making an EV the primary car is the best option for car owners.
