The Electric Vehicle Charging Problem

[Hamburger]

Fee for charging from 80% to 100% be at 50% more than the normal charge. 

Solved.

I hope all chargers will follow this model.

DC rapid/super chargers maybe. But slower AC chargers should not. Else charging would become too much of a hassle.

Idling charge stops charger hogging. Hassle or not is a user issue.

Provider ensure full utilisation at all time

e.g

Charge at work

Battery at 20%
Plug in at 9am, charge at 7kwh, 100% by 3pm  but you are stuck in a 3 hour meeting. what would be the expected behaviour? Before charging need to estimate when it would finish and then make sure you have time to come and move the car? Else should not start to charge? or should move it during lunch time even though not yet fully charged? What if you need the full range of the car tomorrow?

Also at work you may not always park close to your office. Depends on whether season parking is available.   car might be 15’mins walk away  

and it also assumes there is an empty lot for you to move to that you can see/find.

Was at Punggol Waterway Point to catch a movie, saw 3 akan datang Tesla superchargers. It seems they are popping up everywhere in the heartland.

Move the car before 3 pm meeting.

If you have so many concerns and worries, EV is not yet the type of car for you. Perhaps go with hybrids first or PHEV.

The Land Transport Authority (LTA) will launch a tender next month for the deployment of 12,000 charging points across nearly 2,000 HDB carparks, it was announced on Tuesday (Mar 29).

This part of the announcement interests me:

They will also be assessed on their plans to trial and implement innovative solutions to deter the hogging of charging lots, as well as maximise deployment in carparks with limited electrical capacity.

Saw this EV charging area being build at level 5 or a 7-level HDB MSCP. So probably 3 EV charging lots per MSCP...

Just read that Tesla in Singapore will start charging for use of the super chargers and guess what, they will also start to impose "idle fee" if one did not move their cars after full charge.

So I look up what kind of charges they impose on idle fee and you had it spot on; in the US and Canada, if all of the charges are in use and the owner did not move their car within 5 mins after full charge, they will have to pay $1/min.

If 50% of total number of chargers were in use, the idle fee is $0.50/min

I hope all chargers will follow this model.

$1/min is peanuts to some dick drivers. 

In my estate some are willing to pay $100 to park at the loading bay for a couple of hours. 

The real solution is to impound and tow away the vehicles found to be hogging the EV lots... But oh wait, that's gonna require a lot of tow trucks.

Your estate must have a lot of rich people.

1 hour => $60.

A couple of hours could be $240/day.

Over 20 days period, that will be $4.8k.

i guees with the current lack of charging facilities around, owners would want to charge their cars to the max, so as to reduce the times they have to visit the chargers, esp for the tesla superchargers, where it is free charging for now. those tesla owners prob specially made a trip there to charger their cars, so why not make full use of it.

it would need lots of education/fines to make people be responsible and shift away their cars to free up the charger for others to use once their cars are done charging.

Just like our return tray policy. Education has failed big time, so implement fine penalty. No choice, that's our society.

If LTA or hdb is more aggressive with towing and impounding vehicles, I’ll moonlight as a tow truck driver with my own tow truck.

If $1/min is not enough to deter hogger, just increase it to $2/min.

10 mins already $20.

Shake leg money come.

Level 5-7 all got this lot?

meaning one carpark = 9ev lot?

$1 per min....That is like 50x the HDB parking rates. 

But there's no stopping high SES people charging overnight.

I drive an EV (1.5 yrs) and stay at hdb.

I bought the car with an early adopter mindset and am prepared to be inconvenienced to charge. 
 What I mentioned are practical issues which I think will make mass adoption challenging  

while pple here are first concerned with being inconvenienced because charging lots are occupied, they may also be similarly inconvenienced when they have to move their car, disrupting whatever they are doing at that time, so that other people are not inconvenienced. 
I am sure the free market will find the best solution going forward.

Just to clarify, am referring specifically to AC charging between 3 to 11 kWh.
