Recently a friend of mine got interviews with Roland Berger in SEA first round and got this question:
How would you estimate the number of electronic charging station (For electric car vehicle) in Ho Chi Minh City, Vietnam in the next 10 years? (You can pick any city you like for your preference)
Thank you for your answer. The last line: (2.5 - 3millions cars) X (.5) X (15%) could you clarify what is that 0.5 ? I thought it would be 5m people * 0.5 car per person * 15%?
Great catch! I've updated my answer. And, now that I have, the # does seem high, so it would be worth some strong caveats and re-evaluation of assumptions :)
The logic makes perfect sense. The assumption I would change is the number of car per household. We use motorbike predominantly so i would guess 0.1-0.2 car per household now and could increase by 20-30% over next 10 years. . so the actual charging station would be much lower .
