If I am not wrong, Sun Mobility manufactures the Reva brand of vehicles of so not surprising.
But, is battery swapping a good business? I doubt it because people balk at the idea of taking stuff on bhade pe, specially if they have a long time use.
I have no doubt on EVs and related business will boom sometime but not in recent future. Even a network for repairing network which allows companies to offload their capacity to service cars will work wonders.
But, obviously as person in IT we have no idea:
a. How to get huge amount of loans like these conglomerates . Look at Reliance they got Jio running with nearly $1.5 billion in debt. Now they are building a battery unit, which again should be financed using debt.
b. How to get into the market
c. How to calculate profit :)
