Times of India ( 02 July ) carries following news :
SALIENT POINTS :
* MSEDCL plans
to set up 50 e-charging
stations , one every 35 km along the 820 km
Mumbai Nagpur route ( on the existing route )
* When Mumbai
Nagpur Super Highway comes up , we could
have a station every
25 km , said an
official
* AC Chargers take 5 – 6 hours to charge ( electric car battery ) and is economical
* DC Chargers take 30 – 45
minutes to charge but is costly
* A Mahindra e20 takes 7 hours to
charge from zero to full at a slow point and 1.5 hours
at a fast point
.
* A fully
charged car can go up to 120 km
* An MSEDCL
official said :
“ The Mumbai Nagpur highway ( existing )
handles 30,000 to 40,000 passenger cars
DAILY and
hence, setting up charging stations there would be viable for us. We only
need to set up DC charging points that are
faster and this will reduce infrastructure
costs “

WHAT ABOUT CHARGING COST
?
( Source : http://www.pluginindia.com/ev---faq.html )
For example, the
Mahindra Verito gives a mileage of 15 km / litre .
At Rs 75 per liter of
Petrol, the car would need 4 litres to cover 60 kms for a total cost of Rs 300
for the trip.
The Mahindra e2o would need 10 units of power for a full charge of 100 km. At Rs 4 a unit that would be Rs 40.
So there you go, a person driving an EV spends less that Rs 30 to cover 60kms while a gas powered car would really drill a hole in the wallet. On the other hand, if you install Solar Panels, you can run your car on the power of the sun for free.

IMPLICATIONS ON EXISTING HIGHWAY :
# FOR AN ELECTRIC CAR
Mumbai Nagpur ( existing ) highway is 820 km long
With a “ range “ of 120 km , an electric car would need
to recharge 8 times ( to be on the safer side )
So total charging cost could be Rs 320 ( Rs 40 / charge * 8 charges )
Not bad at all
But what about the “ time to travel “ , using an
electric car ?
* Charging time > 40 hours ( 8
halts @ 5 hours / charge for that
economical AC
charging
)
* Running time > 12 hours ( if the average speed of the car is 70
km per hour )
* Lunch –Dinner > 8 hours
*
Sleeping Time > NIL ( just take a nap while battery is charging ! )
* Total > 60 hours
# FOR A PETROL
CAR
Installing Battery Charging Stations along the existing
highway , won’t make any difference to the Petrol cars

IMPLICATIONS ON PLANNED
SUPER HIGHWAY :
#
FOR AN ELECTRIC CAR
Now the planned Mumbai Nagpur Super Highway is going to
be 705 km
So it will take one LESS halt for charging ( ie only 7
halts , thereby saving 5 hours )
So you will be on the road for ( say ) 55 hours instead of 60 hours
But , you will need to pay a toll of Rs 2.5 per km ( total of Rs 1762 / - )
So , for an electric car , the
cost will be as follows :
* Toll Cost = Rs 1762
* Charging Cost = Rs 280 ( 40*7 )
* Total Cost = Rs 2042
Now, even if the cost is “
bearable “ , who would want to sit behind wheel for 55 hours ?
#
FOR A PETROL CAR
Time can
be close to :
* For
driving………………. 10 hours ( @ 70 km per
hour )
* Filling
Petrol……………. 0.2 hours ( for one halt )
* Lunch break……………. 1.0 hours
* Total time…………………10.5 hours [
manageable ]
But when it comes to cost , things look down !
* Petrol
Cost………………… Rs 4,900 /- [ @ Rs 70 / litre and car giving 10
km per litre ]
* Toll
Charges…………….. Rs 1,762
* Total Cost……………………Rs 6,662 / - [ Unbearable ? ]
[ E ]
Observations :
* On the existing highway, no one will
want to drive an Electric Car for 60 hours !
* Setting up
those battery charging stations will be a total waste of scarce funds
Will those 30,000 / 40,000
Petrol Cars which are currently plying on EXISTING highway ( 820 km ) , switch
over to SUPER HIGHWAY ( 705 km ) , so that driving time gets reduced from 12
hours to 10.5 hours ?
Against saving in Petrol
cost ( 820 km vs 705 km / say , Rs 750 / - ) , they would have to fork out Rs
1,762 by way of TOLL charges !
I seriously doubt !
[ F ]
CAN THIS SITUATION CHANGE IN
FUTURE ?
Yes – if :
# Lithium-ion
Batteries can be charged in 5 MINUTES ( instead
of 5 hours )
This may
come about when “ fast charging technologies “
under development by
following
companies , gets launched :
ABB
https://www.thehindubusinessline.com/news/we-have-fast-chargers-come-up-
with-better-batteries-abb-to-manufacturers/article24186896.ece ]
-------------------------------
# Ashok
Leyland launches Metal Air Batteries in
collaboration with Israeli firm
Phinergy [ http://www.phinergy.com/ ] , which DOES NOT
need recharging at all !
-------------------------------------
# Indian manufacturers
of Electric Cars move away from the current design and
move onto :
“ Electric
Cars whose Solar Panel covered roof continuously charges a small
Lithium-ion battery as long as the car roof is exposed to Sun . If at
all any
charging is required , it can be done with
a 220 v domestic outlet ( available at
dozens of
commercial establishments , along the highway “
No need
for dedicated Battery Charging Stations !
ISRO has
demonstrated this technology ( in May 2017 ) and licensed it to Indian Oil
I have no
doubt , if approached , SONO
MOTORS , would be happy to licence this
technology
to Indian Car Manufacturers
--------------------------------------
# If Maharashtra Govt can dream of Hyperloop ,
why not dare to embed Solar Panel
into this Super Highway and pay a “ Reverse Toll “ to
electric cars , as explained
below
?
