Porsche says 80 percent of its cars will be electric by 2030

It has pledged to build out its own range of charging stations.

A few Weeks ago,our Gov't said by 2025,each HDB Carpark with have 3 Overnight Chargers,i wonder if that Carpark have 30 EV,what is the chance of getting the Charger.?

some cars can support fast charging some cannot, assuming every car needs to charge twice a week and each charging takes 4 hours, and further assuming 50% utilisation  efficiency per charging station, meaning half the time a station is not in used, that works out to be about 24 cars per station per week. 3 stations can support up to 72 cars per MSCP. Not to forget, with 3 stations, the utilization should be more than 50%, meaning it would be able to charge more than 72 cars.  Yet to see.

I think charging car will be like charging phones.

Always near full charge.

 

Whereby ICE cars usually pump only when low fuel light came on.

Try to visit as few times to petrol station as possible. 

But if carparks has charging stations....

I will charge to full like handphone...... every single day🤣🤣

For HDB chargers to be effective, penalty measures must be put in place to deter people from hogging the charging points. In Singapore, sadly, only when it hits our pocket the behaviour will change. Just look at the tray return situation, persuade for years, campaigns running for years, suddenly all trays disappear from table when fines are involved.

Get this in place from day 1 and not wait until people fighting at charging points then roll out measures.

Don’t think this idea will fly. Many drivers are old school….. they won’t give up ICE. 
 

Besides charging is a issue that won’t be solved easily. We are dealing with human mindset.

Mathematically yes it can be worked out. But practical  considerations have to be sorted out too. The biggest problem with calculated utilization is it assumes uniform usage which is almost non-existence. The golden charging period would probably be between 7pm to 7am where residents return from work. And if charging allowed say 3-4hours per user, also cannot be people go down at midnight to shift cars. So the real usable charging slot period is a lot shorter. I still cannot visualize how many chargers are really needed to make it work for every MSCP.

The Norwegians are new school? 

Don't think human mindset needs much convincing if EV can be faster, cheaper and better than ICE and they are almost there even without Govt incentives.

EV faces a chicken and egg dilemma but once critical mass is achieved, the market ($$$ talks) will find solutions. I don't understand why people are so worried about having to fight for charging point, these are not expensive hardware that will take years to install.

Think essential goods and services with recurring cashflow. If there are money to be made, such facilities will just mushroom everywhere.

Whatever penalty will not work to deter people from hogging lot - it's the same with illegal parking at loading bays currently. As long as it's just $x to pay, people will continue doing it. 

The only solution is to impound and tow away cars who have exceeded their charge time. 

But yes, I know I'm gonna be hammered by the public for offering such a suggestion.

aiya just stick to ice cars now until sufficient infrastructure is set up

meanwhile just let those inconsiderate ones fight over the charging points

😬😅

I think the opposite actually, when people just over-simplify the solution. Setting up of infrastructure is not just pure economics but also a lot of other functions in hardware setup/configuration, compatibility (new gen charger or battery come out how to handle?), infrastructure setup (sub-stations, power grid etc), licensing (need to go through how many stat board for each setup etc), maintenance, approvals, safety. Maybe i just overthink... but what I dun like is when people use the “没想到。。。” convenient and conventional excuse....

LTA may have screwed up on a few things but truths be told, our road and public transport network are probably better than many other countries.

$1/mins for hogging charging station.

Agree with Singaporean kiasu mentality, not many will wanna risk Low on battery then wanna charge the charger get occupy by an EV that is already full charge 😱😂😂 or still charging 😖
