When I see EVs that are charging at public spots in cities, I assume that the owners for some reason do not care about money. Either because their are rich, or because it is some kind of business expense for them.
- tmikaeld 4y agoLower-cost EVs have a limited battery capacity, so it's unavoidable when traveling between cities. Charging at night with hourly pricing, is just 0.06€/KwH (Sweden) (But going up due to industries switching to night shifts..).
- ls15 4y ago> 0.06€/KwH Is that in the UK? I think in Germany the cost for providers is already above 0.20€/KwH at the moment and the prices at home are typically higher. Mine is about 0.40€/KwH at the moment.
- tmikaeld 4y agoSouth Sweden, if we didn't export huge amounts of energy to Germany and shut down 4 nuclear plants (With 20+ years left of life), it would be a permanent < 0.06/KwH.
- Hamuko 4y agoNight-time electricity can be practically free at times, since people are asleep and a lot of businesses aren't operating. You just need to be on a plan where you pay different rates during the day and night.
- tirant 4y agoIn Germany there are already Smart Electricity suppliers which also provide a Wallbox in order to automatically charge your car whenever certain price threshold is reached. You could for example configure it to charge your car when prices are even negative. That's not so common anymore, but we had a price of -0.08€/kWh on 21.05.2021. 10 days ago, the prices were also pretty low (0.02€). https://www.awattar.de/tariffs/hourlycap https://www.awattar.de/tariffs/hourlycap
- mellavora 4y agoNice theory, assumes that prices stay below your threshold long enough for the car to charge. It can happen, as your examples show, but can it happen at scale, i.e. when 1 in 10 people are running "full house equivalent" energy requests every time the price drops below say 0.02 EUR/kWh? Been pricing electicity derivatives at work last week; with that context I'm now thinking of your scheme as a limit order, and what happens when the market is oversaturated with limit order?
- the_mitsuhiko 4y agoI’m confident that most public charging are long distance travellers away from home with limited choice.

- gambiting 4y agoWhy would you assume that? I know someone who has an EV but lives at a home without a driveway, public charging is the only way for him to actually you know, use that car. As EVs become more and more popular, that's how most people will charge their cars, it's not like everyone has a house with a driveway.
- tirant 4y agoNot really. Electricity tariffs can be pretty competitive if you shop around. I own an EV and I have never charged at home, even though I have my own garage. My average electricity costs at home are around 0.30€/kWh. Meanwhile, 30% of my charges have been cost-free and the rest I'm paying between 0.12€/kWh and 0.39/kWh. The investment required to install a wallbox is not really worth it at the moment. It would just add convenience.
- bradlys 4y agoFunny - I assume the opposite because they're spending their time at a charger rather than plugging it in at home. If they can't charge at home - that probably means they don't have a home but maybe an apartment without a garage that has EV hookups which means they probably don't have much money. The other alternative is road tripping.
- cvak 4y agocan confirm, have business ev charging card, free parking baby.
