content: here is a video about a hypothetical cheap mass market EV.were cost is important.see videomy opinion for a cheap mass market EV the Cadogan Shitonx or GreatWall EV.a steel car body can have a cost saving but with a weight penalty.however if the vehicle body is a small three door hatchback.loss steel is needed in the body. also less quarter glass. less side door windows.smaller motor with torque gearing can have a kw saving with a top speed penalty.tesla model 3 has a top speed of 261 km/hwhen only a top of 115 km/h is needed for a cheap mass market EV.sluggish performance over 90km/h is tolerable for a mass market city use EV.as long as good torque performance in the all-important stop-start city cycle 0 to 50km/h speed range.removing power windows and power electric car seats has both weight & cost savings.them accessorys add up. basic 15w twin speaker in car stereo system is less the a full 6 speaker sub-boost quadraphonic system.more cost & weight savings.do you have better opinions for a cheap mass market EV ?cost is important. so a small battery

content: Such a car already exists:https://en.wikipedia.org/wiki/Smart_(marque)and it isn't selling really well because small cars only serve a niche market.

content: Citroën Ami is like 6k Euro, although debatable to call it a car, more a VSP or Quadricycle, but would suit me down to the ground for zipping around town.Of course in America it would be pooh-poohed as too small.

content: Not so cheap niche market junk. Must be a great idea to make a small crippled car! No? Then why should it work for EV in particular?

content: Chinese are doing it already.Some cars are available in Europe with low prices (subventions deduced) of 10k :Suda SA01 for 10 000Euro :<- really impresive 40 kWh !!!!!!!Zhidou D2S should be available soon for about 10kSeat Mii/ skoda Citigo/ for about 9000Smart fortwo / forforPeugeot ION/Citroen C-Zero/mitsubishi I-miev for 10 000 Euro (old design, very small battery)Many more are available in the 20kEuro class.....Nice price list before subvention:https://www.bafa.de/SharedDocs/Downloads/DE/Energie/emob_liste_foerderfaehige_fahrzeuge.pdf?__blob=publicationFile&v=142

content: The really really important thing for a mass market EV is a DC charging of 100kW minimum, in the base variant (not a costly addon)For a near zero addon cost, this makes long distance travel possible and really practical.All compliance cars cannot do it. Don't buy any car under 100kW.If you choose an EV, look at the average DC charging speed, it's really important.

content: Quote from: f4eru on January 02, 2021, 01:24:36 pmI don't agree, fast charging reduces efficiency, battery life and increases cost for the charger and infrastructure.If you want to travel long distances regularly, don't buy a (cheap) ev.

content: Don't forget the the Wuling Hong Guang mini ev. It is small cheap and sells incredibly well, not like a niche car more like in the top3 of electric cars.

content: Quote from: The Soulman on January 02, 2021, 02:08:26 pmThat's an really obsolete way to say that cheap EVs can't do long distances.Today's EVs simply can do that without real impact on battery life.Fast charging and liquid cooling should be standard, we are in 2021.EVs with air cooled batteries, or without 100kW charging are really obsolete. Don't buy obsolete new stuff.

content: Quote from: f4eru on January 02, 2021, 05:12:37 pmSo your saying is to avoid all 10,20 and even 30K electric cars and only buy from 50K and up if you want a cheap ev.

content: my thoughts something between the all so basic Citroën Ami and the more powerful Renault or Suda SA01 EV would do for Australia.a Changli maybe too small. world's cheapest electric car.Australian motor vehicle regulations would need to accommodate mini minor sized EV's here in Australia.as a new class of vehicles in there own right.seeking the best compromise between keeping vehicle costs low and any new crash safety requirements.as a low top speed would not need the same level of crash safety as other more powerful class's of vehicles.however a top speed of 62 km/h would avoid slowing city traffic.Quote from: The Soulman on January 02, 2021, 05:49:33 pmcars under 100kW would have there own class of carpark charging no different then say electric motorcycles.

content: Nope.VW ID3 and ID4 can charge 130 kW for 32k (25k with incentives in some countries)Opel Corsa-E / Peugeot e-208 100kW 27kAiways-U5 90kW 29kFiat 500 : 85kW 26kHyundai/Kias can do 77 kW, close enough compromise for less than 30k depending on countryMG ZS EV 76 kW 30kLatest leafs can accept 100 kW, but are hampered by their air cooling, also less than 30kMore coming.Fast charging allowing long distance is a reality now at the 30k level, and quite soon at the 20k level also.Also non-tesla fast charger networks are being built fast in some parts of EU, making old style triple chargers (and non-CCS cars) "obsolete".Don't accept new cars that cannot travel far.
