14 - 20 years ago every mobile phone manufacturer had it's own plug for charging their phones. They have agreed on having one standard now. However they have not agreed on form factor and similar standard for the Li batteries used.

 

Right now there are a number of different plugs and standards for charging EVs.

 

EV traction batteries even within the same model line (e.g. Leaf) are different. What I would like to see from EV manufacturers is unification of EV batteries used and plugs for the charging infrastructure. That in my opinion will boost uptake of EV tenfold as people would think: I like that model because of it's appeal and I am confident I'll be able to fix/change my battery in the future with no problem. As a manufacturer - you just improve look and shape every year, but make standard batteries.

 

It seems only Toyota (& it's joint venture EV Energy) with it's unification for NiMH in their almost all models of hybrids has brains and forward thinking. Same modules from EV Energy are used in Nissan Hybrid and some other makes and models.

 

Other manufacturers are not as smart as Toyota IMHO.

I was at our local New World Lincoln (chch) and noticed they have recently installed charging points, don’t know the details, but what also caught my eye was this !!



Not an ev owner yet but interested. Thought it might interest you all.

In case you don't know, this is the van version of the Nissan LEAF. It's the e-NV200. The battery is 24kWh. Range is about 140km. 
You can get them in 5-deat and 7-seat versions....as well as an empty van. 

In the EU, just this week, they announced a new 40kWh version of this van. Range should be 200km or more. :-)

Aredwood:

 

One of the big problems with electric trains is you need a busy line to make the economies work out. As electrical capacity is expensive to install. You need really big transformers and cables to supply enough power to run an electric train. And due to voltage drop, you have to split the electric network into sections, with each section having it's own transformers and supply equipment.

 

 

 

 

Yeah, but on the main trunk line they are retiring an electric system that is bought and paid for - cost of install isn't the problem, the cost of re-install in 20 years time is the problem so this is the beginning of the end. A crying shame and removes a layer of insulation the railways had between their costs and fuel prices. Next time oil hits $140 a barrel, the railways will have lost another small competitive advantage they had over the trucking companies.

Theres an new world ev here in dunedin too.
Hopeful sign that they will be installing slow chargers in supermarkets here like chch.

A number of cafe/shops have them too.

A friends got one with 3 rows of seats as he was 3 sons with alot of sports gear.

gZ won’t let me upload the screenshot, but Pukekohe now has TWO CHaDeMO chargers available (only one month after the first went live!)

Thanks Counties Power!

This should help the growing use out here, and help avoid the queues that are starting to form (2 behind me today, and one behind another in front last week 😳

Ideal application for a little EV-van.

Cheaper batteries in the future looking very good, on several fronts. Here's a new one.

http://newatlas.com/sodium-ion-battery-cheaper-lithium/51682/

"Sodium-ion battery beats lithium for cost effectiveness

Michael Irving

A sodium-ion battery, designed at Stanford, can store as much energy as a lithium-ion battery for less than 80 percent of the cost

Lithium-ion batteries are the current reigning energy-storage champion, powering everything from phones to cars. But as good as it is as an electrode material, lithium is relatively rare, and the cost of mining and refining it can blow out the budget for large-scale applications.

The search for a cheaper alternative has led some scientists to plain old salt, and now a Stanford team has developed a sodium-ion battery that would beat lithium-ion batteries in terms of cost per storage capacity."

Right at the end of that article it says they have yet to determine the “volumetric density” required for this battery, which means they don’t even know how big it will need to be to produce this 80% cheaper battery?

There’s no way phones laptops or even EVs will switch to this if it takes us back to huge, heavy and bulky battery packs like the lead acid are, as convenience, weight and size are MAJOUR factors in all three of these uses... so if it works out to big/heavy, perhaps grid and powerwall setups might use it alleviating the pressure on Lithium, but cars phones laptops and wearables NEED light and thin to be effective.

Solid state batteries look promising. They never degrade. 

"So-called “solid state” batteries have both solid electrodes and solid electrolytes. Solid-state batteries can be made smaller and lighter than the lithium-ion batteries that currently power electric vehicles, but engineering such a battery at an attractive price point for mass production has been a challenge. The Chunichi Shimbun reported that Toyota’s battery will be able to charge in a few minutes and have a long range, but the article did not list specifics.

 

A solid-state battery would also reduce the fire risk that comes with lithium-ion batteries that use a liquid electrolyte. And, because the electrolyte wouldn’t be in danger of freezing, it could withstand a wider range of temperatures."

Cool article... though I’m quite interested in how they think they’ll be able to charge it enough for a large range “in a few minutes”... isn’t that’s Tesla’s main challenge in rolling out its supercharger network?

At Green lane this last week I saw a Tesla with a 1-hour charge-to-80% estimate from a 17% SoC on a CHaDeMO (via their adapter) and the picture in your article seems to show a CHaDeMO and standard ‘EV’ plug!

Will we be seeing another charge network roll out in 5 years? Perhaps a L3 grade setup taking over from the current one, like ‘Type2’ just took over from ‘Type1’ 🤔
