The Electric Vehicle Charging Problem

[Ingenius]

This informative video explains the real world challenges that electric vehicles are facing, which is not about the cost, battery technology and range.

If petrol go above $4/litre. 

The ev charging problem is not a problem. 😭

That's why it is good to wait a little for the battery technology to reach the faster charging rate. 

I am looking forward to the solid state batteries which have a higher energy density, hence use lesser amount of batteries which translate to lesser kerb weight. No risk of fire unlike the Li-ion liquid batteries most ev are using now. Hopefully more efficient charging and less waiting time.

The tech is there already.  Do you have the $$ to buy the car?

In addition, charging rate is dependent on the installation of faster chargers.

The latest battery technology for battery pack is Lithium Iron Phosphate (LiFePO4). Much higher temperature tolerance and more charging cycles before degradation. Now use in in-car battery packs and I think it will be used in some EV battery packs soon.

This video explains that the price barrier of usd$36k, 31 minutes charging time and minimum range of 291 miles, have been overcome.  The problem with ev adoption is that the cost of building a 250kw charging station is about $350k, and is not proliferate yet. And so this translate to not enough charging station being built, and this pose a problem of ev vehicle unable to charge and acheive a range longer than 291 miles, when travelling between states. 

It is a problem with infrastructure, as it is a chicken and egg problem. One charging station is built for every x number of cars. Not enough cars, not enough charging station.  And the electricity grit also has to be ready, which is not built to be, long ago. 

 

And different ev uses different adapter, like Tesla is different from Nissan. 

Something like that.

Sg got unique problem which is our national grid cannot tahan if all adopt at once

Grid can tahan.

MSCP electrical infrastructure needs to be upgraded 

[Atonchia]

Can we get fuel cell cars?

That’s why for the longest time alibaba on EV. 
it’s not the power stations. It’s the distribution grid.

In a way the grid. The 66kv is ok. But the 22kv and below are the issue.

For now evs need to go the way of going to recharging stations to swap batteries. Automated robot arms take out old batteries and put in freshly charged ones. But means all EV makers must agree on common standard, size and fittings.

Hydrogen fuel cell?
Where to pump?

Gogoro also hit into problem when large number of users swap battery.

A lot of batteries are not fully charged.

There is no perfect solution.

Users need to be agile

1) Get from LPG suppliers?

Or

2) petrol station can install liquified Hydrogen tank underground?

 

get their supply from such companies.

I think most gov prefer EV because they get tarrif from selling electricity.

If sell gas, not sure there is framework to tax the sales. 

Petrol is also straight forward. Have excise duties and GST collected. 

but I think selling liquid hydrogen is faster than charging batteries.

or SG should allow both system to run concurrently. Allow consumer preference. 

car power output will be main criteria for road tax and COE.

Currently there are only hydrogen fuel cell car.

Toyota Mirai: USD50k

Hyundai Nexo: USD44k.

There is insufficient number of cars to justify the infra.

As Hydrogen is sold by weight, no issue with tax collection.

In US, most of it in Cali (43 out of 45).

You can’t just drive into airliquide to pump

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.?

Air liquide to sell to retailers.

I think EV cars are preferred is the torque and acceleration it offers compare to Fuel cell car.

Though the EV charging takes a longer time.
