Do electric car batteries give off gas, the same as the battery on my non electric car?
I see badges on electric cars proclaiming "Zero emmisions" which make me wonder about the battery.

AIUI the gas involved with lead acid batteries is hydrogen and a result of the electrolyte breaking down while charging. I seem to remember that one can produce hydrogen from water via electrolysis. We had a 'Genski' lesson at school where we the hydrogen could be lit with a splint and go pop!.
No modern electric car uses lead-acid for the propulsion battery so I suspect the answer is no.
Zero emissions though refers to the tailpipe, or rather lack of one.
It takes no account of what's used to generate the electricity or what's consumed in building the car and its parts.

The batteries in an EV are all sealed, any form of venting means they are toast and need to be replaced.
I see quite a few specialist suppliers are now offering battery cell kits on some cars. Means stripping the pack apart to replace the cells, but replacement is half the price of a new complete pack.

Or delivering them to the dealer with a diesel guzzling HGV transporter.
I see there is also a risk of older multi-storey car parks not being able to cope with the extra weight of electric vehicles and could collapse.

Just as relevant to say that older car parks won’t be able to cope with the every growing size and weight of large SUVs whatever their means of propulsion.

From the DT
Sheer weight of electric vehicles could sink our bridges
Councils receive notice that EVs are 33 per cent heavier than petrol vehicles - and 1 in 20 bridges are ‘substandard’
Councils should check the weight limits on bridges to ensure they don’t collapse with heavier electric cars travelling across them, ministers have suggested.
Transport minister Jesse Norman said that it was up to councils to decide whether "weight limits" should be applied to their bridges.
Sir Greg told The Telegraph that councils could check the specification of the plans for the bridges when they were constructed to ensure they can support the extra weight of the vehicles.
.....I do not think ancient bridges have specs

Scaremongering.
Many vehicles are heavier than an EV.
Sources on the internet say that an Audi A8 is 1962kg, a BMW 5 series is 1695kg, a Berlingo is 1540 - 1664kg and a Tesla Model 3 is 1729 - 1847.

What you need to compare is the weight of today's average family hatchback/multi-storey inhabitant with it's electric equivalent.
For example, todays's Golf (1264 to 1630Kg) compared to an ID3 (1813 to 1936Kg).
|
The source for all this drivel tell you what you need to know.
Since a typical family hatch weighed 800kg 40yr ago and now is twice that and bridges aren't collapsing everywhere, I suspect it is good old oil at work via the Telegraph/Mail.

>> bridges aren't collapsing everywhere,
Not quite true. They do. But that has much more to do with the sheet way they were built and the sheer volume of stuff on them. If your bridge was built for 50k per day at 1,500kg each in 1960, now its currently taking 100k per day at 1800kg each, in 2035 its going to be taking 125k per day at 2000kg. Almost certainly thats gonna be at or over its 1960 design limit. But hey thats just obsolescence at work.

What I find interesting is that there are many medieval single arched stone bridges aground which were designed for a horse and cart but which are coping with modern traffic. Very far sighted in the fourteenth century.

... there's long been a saying; "anyone can build a bridge that won't fall down, but it takes an engineer to build one that just won't fall down" ;-)

Most of them have been bypassed, weight limited or strengthened. I have a 1700's stone arch bridge near me. Its been single trafficked and weight limited. Still a damn fine bridge tho.

Concern about the weight of EVs in car parks is all but complete scaremongering garbage.
The car park not only supports the weight of the cars within it, but also the weight of the structure (walls, floors, access ramps etc etc).
Not only are these several times the weight of the cars they support, they would be designed with a substantial safety margin.
Assume the average car park space is 10 sq m and the deck supporting the car is 300mm thick, the total volume of concrete is 3 cu m. Concrete weighs 2.5 tons per cu m - the weight of just the deck holding the vehicle is 7.5 tons.
Multiply by (say) 3 to cover access, ramps, pedestrian walkways, walls etc gives a structure weight of ~20 tons (20,000kg) per vehicle. Adding (say) an extra 400kg for EVs would increase the load by 2%.
Any building is so close to collapse that a 2% increase in loading would cause failure should be closed immediately. Structural engineering calculations are simply not that precise.

Sorry thats all apples and pears.. EVs are heavier than their petrol equivalent. N-one knows how much a Tesla petrol would be cos their aint one, and its built like flypaper.

The point was that EVs are heavier than standard cars, so I listed some fairly common cars which are nearly as heavy/more heavy than some common EVs, and no bridges have fallen under them as far as I know, and I don't think anyone has suggested car parks will collapse beneath them.
I didn't even mention laden vans or trucks for the bridges point.

1570 kg MGZS EV
1258 kg MGZS
They are. EV Power trains are about 200kg on average heavier than ICE direct equivalent. In real life thats an issue for range, handling and ride, but I agree car parks and bridges are a non issue.

I'd love one of these. I saw one in Whetstone parked next to a little pizza take-away outfit, they were clearly delivering in it. It's got my daughter's name, too.
Total pulling machine, guaranteed.

Yeah, y’see, I’ve never dared to get a pulling machine. I’ve been harassed enough by women all my life without adding any fuel to that fire. Crosses to bear and so on I suppose.

Get that little Ami, and your problems are over. The only thing you'll be pulling in that is rice pudding skin. (just)
|
What I love about them (apart from all the female attention I'd get) is that the passenger door is a normal door but the driver's door is a suicide door.
It'd keep me awake. My entire life is usually all about perfect symmetry. OCD. But the Ami breaks that rule.
|
There’s a large glass palace Citroen dealer in Benissa (Alicante province) which I drive past several times a week...they always have a few of those AMIs parked outside and some really old Citroen’s on the showroom floor.
Google ‘Citroen Benissa’ for photos...
