Tesla has been around for nearly 20 years. Model S (12 years) has gained 17% of range due to chemistry (rest is system efficiency and simply bigger battery).

BMW i3 went from 60Ah to 120Ah of battery capacity (and slightly more voltage) in the exact same chassis through the span of its life (2014-2022, RIP). It is even possible to put the later 120Ah batteries in the early 60Ah cars and reap the rewards, and is a practice that is actually supported by the cars' software natively.

Range is not a real issue for electric cars. Charging time is, though, and there are massive improvements happening for that right now.

  • Tell that to my polestar 2 pls. and then come back again in the winter when it drops another 30% due to the battery heater energizing

    • Your Polestar 2 battery is based on battery technology that is 5+ years old. Right now you can buy a BYD car in China that charges at up to 1500kW - close to 10x the peak charging rate of a Polestar 2.

  • I would wager charging time is basically solved, adoption is only thing that's left.

    • Yeah, when I take a road trip I genuinely enjoy the cadence of charging. 5-10 minutes every two hours, just enough to go to the bathroom or walk around. I get to my destination not materially later, and feeling far more relaxed than when I was doing death marches in a gas car.

  • Its a huge issue in cold climates.

    • uphills + cold/hot climates, the ranges won't be able to compete with ICE. its basic physics. cold uphill still reduces charging speed, available power, and range, while sustained heat accelerates degradation. Thermal-management systems mitigate those weaknesses by consuming energy and adding cost, weight, and complexity.

      meanwhile ICE has gotten ridiculously clean and efficient over the years it is more efficient at the shaft does not settle total-system efficiency, cost, weight, resource use, grid losses, battery production, or suitability for every operating env. Comparing an engine with a motor while ignoring the battery and electricity supply chain is silly

      I still do not trust that sitting on a pile of lithium batteries is safe. NMC does not mean non flammable or consequence free. LFP cells can still enter thermal runaway, release toxic gases, reignite, and require difficult firefighting procedures. They also generally trade energy density and cold-weather performance for that improved safety. Also the speed charging ? That dramatically reduces the stability and lifespan of the batteries. Ton of used EVs not being sold because the battery replacement is somewhere between 40~60% of the car's value.

      we had ICE for over a century now, its just like a software that gets continuous updates ICE systems are highly optimized, repairable, energy-dense, fast to refuel, and supported by enormous infrastructure. EVs are improving faster partly because they still have major weaknesses to solve. A steeper improvement curve does not prove that the present technology is superior for every use case neither is using the latest javascript framework.
