Would you have an electric car if you had the money for a new car and were in the market for one?

[Asian Boss]

Pooled, driverless, electric micro cars.

For the polluting proles anyway.

Apple is close to finalizing a deal with Hyundai-Kia to manufacture an Apple-branded autonomous electric vehicle, sources previously told CNBC.

[Mr. Dazzle]

Guy I used to work with left McLaren to go to Apple a few years back...AFAIK he's still there. Apple have been in and out of this for ages.

Noted Apple analyst Ming-Chi Kuo has confirmed initial reports that Hyundai will be Apple’s key manufacturing partner. Apple might use Hyundai’s latest electric vehicle platform E-GMP, and that gives us a basic idea of the specifications one can expect. While Apple and Hyundai are both yet to confirm the partnership, the most recent report from Kuo has more or less confirmed it. However, according to the report, one can expect Apple to launch the vehicle no earlier than 2025.

The Hyundai E-GMP
Hyundai unveiled the E-GMP, i.e., the Electric Global Modular Platform, last year. It is a vehicular platform built specifically for battery electric vehicles (BEVs). The South Korean company stated that both Hyundai and Kia will use this platform in their upcoming electric vehicles. The upcoming Ioniq 5 will be the first electric vehicle to use this platform.

Will it have a proprietary Apple charging socket?

[Mr. Dazzle]

This popped up in my recommended YouTube stuff today and I thought some of you might be interested. Talking about large flywheels for energy storage at industrial scale.



This is something I've worked on quite a lot with composites. Carbon fibre is ideally suited to this application cause you can make it really really strong. Our highest performing rotors could nudge 1,000,000g at the edge when spinning at full speed.

The power density compared to a magnet was huge, up to 10 times the power/weight ratio. Overall storage capacity was less, but they can certainly soak up a lot of juice very quickly.

[Yambo]

Shouldn't we be using the word 'accumulator' a lot more when talking about energy storage systems?

Over here in Turkey a battery is a 'pil' or 'batarya', normally pil. You use them in the TV remote or torch etc. You wouldn't buy a pil for your araba (car) though. You'd buy an akü and while google translate may well translate akü to battery, it's doing so just to reach your level of dumbing down.

[Horse]

Isn't you 'pil' a single cell and a 'battery' a number of cells together?

What is the difference between a battery and an accumulator?
The term "battery" is used both as a generic term for energy storage and as a term for a non-rechargeable energy storage (primary battery). Whether a non-rechargeable primary battery (e.g. long-term use in watches) or an accumulator (e.g. in smartphones) is used in a device depends on the use.

Where are batteries and accumulators used?
In practice, a distinction is made between two different types of energy storage: primary and secondary batteries. Primary batteries can only be discharged once and cannot be recharged afterwards. Secondary batteries, commonly known as accumulators, are rechargeable.

Regarding application, it is distinguished between device batteries, starter batteries and industrial batteries. While portable batteries are mainly used in wristwatches, smartphones, laptops or torches, starter batteries are mainly used in cars. Industrial batteries are installed in stationary applications such as uninterruptible power supplies, mobile phone base stations or forklifts.

What is a battery and how does it work?
A battery is an electrochemical energy storage. It usually consists of a combination of electrochemical cells, the so-called galvanic cells. These cells contain two electrodes separated by an ion-conducting, liquid or solid electrolyte. These consist of different materials (e.g. lithium, alkali manganese, lead). Depending on the chemical system used, the battery systems have different voltage levels and energy densities. The material used for the electrodes determines how high the nominal voltage is. The energy that can be stored depends on the nature and amount of material used in the battery.

During discharge, the energy stored in chemical form is converted into electrical energy by an electrochemical reaction and electricity flows.

What is a cell?
A cell is the basic functional unit of a battery, which consists of an compilation of electrodes with active materials, electrolyte, containers, connections and usually separators. The capacity of a cell results from the size or weight, the internal structure and the material combination of the electrodes.

What is a battery management system?
A battery management system is an electronic circuit that enables the battery to function properly and monitors its characteristics, such as the voltages of the individual cells of the battery, the voltage of the cells under load and the internal resistance. Safety-relevant events such as overcharging, deep discharge, high temperatures, short circuits, etc. are also detected and prevented during operation.

Isn't the internet wonderful.

I'd learnt all of that before 1970.

[Horse]

I was at school then, so probably didn't learn very much

Still, the first paragraph answers your point:

[Rockburner]

I always thought a battery was a collection of multiple instant mass-death projection devices.









from searching:
Middle English: from Old French baterie, from battre ‘to strike’, from Latin battuere . The original sense was ‘metal articles wrought by hammering’, later ‘a number of pieces of artillery used together’, whence ‘a number of Leyden jars connected up so as to discharge simultaneously’ (mid 18th century), giving rise to battery (sense 1).

[Mr. Dazzle]

Jaguar announced today that they are switching to being an all electric brand.

A few years ago that would have seemed more radical, but of course in the not too distant future all brands will be electric (in Europe at least).

Interestingly they are also gonna start doing hydrogen fuel cells more seriously.

The most significant bit of that announcement is the last sentence. Electric cars are only a stepping stone to proper alternative fuel cars.

[Mr. Dazzle]

Fuel cell cars are still electric, they just use a fuel cell and not a battery to store electricity.

EVs are the future one way or another, it's just a question of how the electricity is stored. As I've said before, it's very likely that even a hydrogen fuel cell car will have a battery as well.

I'm not so sure, whilst filling up at a filling station is fast it's still always not as handy as plugging into the garage. For some people thats the simplest way.
Not for me mind, I park on the street.

Faster charging with longer range batteries/solid state batteries is coming on quite fast or just round the corner and as Dazzler points out hydrogen cell cars still have electric motors anyway.
I'm not totally convinced that hydrogen is the most convenient fuel to store and fill up with either.
Japan does seem to be having a good go at it so they obviously rate it.

Dunno, we'll see over the next few years but electric motors are still happening whatever.
Normal hybrid cars seem to be an evolutionary dead end though, to me thats just adding complexity.

A few years before your few years ago, the idea of Jag going diesel would have been laughable. How times change, and increasingly quickly.

[Couchy]

Can add a little to this as we have sold my car and the wife’s car and bought an A class plug in hybrid, not quite full electric but after looking at our use and with wife now working from home we realised 90% of our journeys were under 40 miles. The A class has one of the better ranges for a plug in at 40 miles. 3 weeks in and apart from one long work journey all our use has been on the battery. Saving so far on fuel taking into account the electric cost is around £80. Best bit is not filling up each week, I’m liking electric driving too using regen to slow rather than brakes. Next car will prob be a full electric version of this

[ZRX61]

You may have seen news about the weather getting a bit nippy in Texas etc causing big pile ups on the roads etc. Now they're having rolling power blackouts & a bunch of the windmill generators have frozen solid.
Jobamala has come to the rescue by declaring a state of emergency.

Time to fire up the gas powered plants I guess.

[Mr. Dazzle]

When they built this place (MK) more than 50 years ago now they went for the whole 'less cars' mantra. For those who don't know, MK basically has two road networks - one for cars, which is mostly dual carriageways and the famous rounabouts, and one for pedestrians/cyclists which is generally completely seperate from the roads and covered in red tarmac. Hence the name; redways.

It's possible to get nearly everywhere in the city by bike or by car with equal ease. People still drive everywhere!

The really annoying thing is, even though they built the place to allow cycling they also built it to avoid traffic and parking congestion. However the council seem to insist on trying to be like every other town and having traffic calming measures, pedestrianisation of roads etc, no parking etc.
