Electric Scooter Feasibility in India - September 2017 - Part 2

The previous article in this series is at: http://aajkyakiya.blogspot.com/2017/09/electric-scooter-feasibility-in-india.html

To continue with the electric cost calculations, we will now see the cost of charging the battery in a commercial charging station.

Why is this needed? Well, you will sometime have to charge your electric vehicle's battery from a charging station (equivalent of petrol pump for petrol based vehicles). This will definitely be required while on a long drive or in an emergency.

The tariff (of course the max one) for a commercial establishment in my area is:
Consumer Category & Consumption Slab: LT II - LT Commercial
> 50 kW load: Rs. 240 per kVA
Wheeling Charge (Rs/kWh): 1.58
Energy Charge (Rs/kWh): 7.60
Regulatory Asset Charge (Rs/kWh): 1.11
On top of this we have GST 18%

As we have seen in our previous article, our scooter's battery requires 1.345 unit of electricity to charge 100%. So, for every charge in a commercial charging station, the cost will be:
(240 * 1.345) + (1.58 * 1.345) + (7.60 * 1.345) + (1.11 * 1.345) = 336.64 + 18% GST = Rs. 397.24

This is more than the cost for charging the scooter's battery 12.5 times at your home.
i.e. cost for 1 time at charging station > 12.5 times at home

Also note that the electric cost will increase every year, by next year the cost for the same 1.345 units will be Rs. 413, in another year this cost will be Rs. 426.

Now, suppose the equivalent petrol scooter has a 5 litre capacity, then the petrol charge would be: 5 * 80 (considering Rs.80 per litre) = Rs. 400.

So the electricity cost and petrol cost will nearly be the same. The only thing in favor of electricity is the range (km per charge) the scooter will give. But as we have already mentioned in the previous article, the range will go down substantially after the 1st year. So, we will get less and less range with each charge every year (or every month).

Now, on top of this charging cost, we have to add the battery cost of Rs. 20,000 every third year. This makes the electric dream a cost nightmare for the average consumer.

Update (29 Sep 2017):

One more calculation:
For each 100% charge, our scooter gives 48 km in the 1st year, 38 km in the 2nd year, and 30 km in the 3rd year.
And as calculated above, a 100% charge at a commercial establishment will cost around Rs. 400.

And, in Rs. 400 we get 5 litre petrol. This will give us (40 km per liter * 5) = 200 kms.

Per km cost for petrol = Rs. 400 / 200 kms = Rs. 2 per km.
Per km cost for electric = Rs. 397 / 48 kms = Rs. 8.27 per km. (1st year)
Per km cost for electric = Rs. 413 / 38 kms = Rs. 10.87 per km. (2nd year)
Per km cost for electric = Rs. 426 / 30 kms = Rs. 14.2 per km. (3rd year)

At this cost, a commercial electric charge is more than 4(/5/7) times costlier than petrol.
In addition, do not forget the Rs. 20,000 battery to be bought in every 3 years time.
