    I’m not a car person, so excuse my lack of knowledge. But do electric cars have/need cooling liquid? Just wondering

      Some have cooling liquid for the battery and electrical components. Some blow cold air over the battery.

      And then there’s the Nissan Leaf, which just lets the battery cook, knowing that it probably won’t die before the warranty is up.

      Though it’s a bit more complicated than that - sometimes you want to heat the battery or the passenger cabin, and sometimes you want to heat one thing while cooling the other. A good thermal control system can handle moving heat around as well as getting rid of it or taking it from the surrounding air.

      An EV doesn’t produce so much heat that it needs powerful cooling like a gas car does, but it does come in handy if you want to rapid charge a few times on a long trip. You can get away without it if you’re being gentle with the car and live in an area with a mild climate.

      Most electric cars have battery cooling, but the Nissan Leaf doesn’t. It works fine until you try rapid charging more than 2 times in one day.

      I suspect that some high performance cars would also have motor and inverter cooling. This would likely not be needed for regular road cars as the motor and inverter don’t produce much heat.

        This is true however for op it’s not something you can or need to watch or keep track of. At least for my car if it detects something wrong with the battery cooling/heating system it will tell you. Otherwise you just ignore it.

      yes an electric motor has an efficiency of around 90%(thats what my engeneering teacher told us)(google tells me 64%) means that is the percentage of how much energy is converted to work the rest of that is emmited as heat. a good rule of thumb is everywere where you have mechanikal work you have frction and friction means heat

      I have a hybrid Prius (not a full EV) and it actually has two separate coolant reservoirs, one for the gas engine and one for the electric motor, and they both use the same kind of coolant.

          It is the engine temp, and red is overheating which damages the engine.

          So if you knew that you could have made a joke about one fewer climate destroying engine. Know your enemy!

              You just didn’t notice it. If you’ve owned a gasoline car, it had a temp guage, since it is a requirement.

                I have a 2019 car and I think it’s now a warning light, but I do have a useless gauge for what my current mpg is that I would gladly swap with.

                  I hate moving gauges to warning lights. Gauges can help you troubleshoot and catch issues before they’re a catastrophe.

              Some cars you won’t notice it because the system works well and once it slowly rises up to operating temp it doesn’t move again. Some cars you would because they are designed stupidly different. Like Dodge. I had a mechanic tell me after some research that yes indeed, the cooling fans not kicking on until the needle hit red was by manufacturer’s specs.

          They are, but not quickly enough.

          Ten years ago we got the Nissan Leaf, and now you can buy cars with 2x the range for almost half the price.

        It’s the part about being happy about it that I don’t like. I drive a hybrid, but that’s about saving money more than anything. I’m not happy to see the tank at full. It just reminds me of my contribution to making things worse.

          Aww man you’re falling for their bullshit 😞

          The biggest impetus to change isn’t your personal consumer habits. It’s industry. And they want you to feel like YOU aren’t doing enough while they do jack shit except fuck over the rest of us every day so they can jerk each other off with their quarterly earnings reports.

          (I’m not saying we should all be rolling coal, that’s stupid and gross and childish. Just that we shouldn’t internalize anxiety about ‘doing enough’)

              Well, if you drive a hybrid, have you ever thought of where your electricity comes from? Probably a very inefficient coal or natural gas plant! Also, its not the gas gauge, its the engine heat gauge lol.

              Point is, don’t fret over your fossil fuel usage. Big corporations use more fossil fuels a day than you will ever use in your lifetime, even if you drive a fuel guzzling truck.

                No, I know where it comes from. The car’s internal combustion engine. Because that’s how hybrids work.

          Let’s all live in shame because we can afford electric. I hate to tell you the huge amount of emissions that go into producing the electric cars in the factories too. Also the non-renewable resources that go into them.

            $300/year to drive 10,000 miles per year feels pretty good though. Also, zero emission at the tailpipe.

            Everyone will be driving ev within 10 years.

                  I got an 02 Subaru outback in really good condition, and only 196k miles. I still got a few years. When it dies, I’ll probably get a car around 2012 or so. No way it’s cheaper to get an EV then to buy used.

          I mean, having to worry about getting around all month on a mostly empty tank, side-eyeing the gauge at every traffic light at the commute to work isn’t that great.

          I know a few people that had a hard time paying for gas to even get to work and when they managed to fill the tank they felt relieved, so I can understand where those people come from.

          I personally am glad I can work from home, just saves so much gas. Fill it up, use it for 1-2 months to buy groceries, visit people, drive to the few work appointments that don’t work over Teams.

            It doesn’t go bad so fast though.

            As a rule of thumb: gas is good 2-3 months in a car tank, before it’s ability to properly combust deteriorates. It wont go bad immediately, but it’s power yield worsens over time, so does your car’s mpg, because it needs more gas to compensate.

            Just don’t let it sit there like half a year
