| Like most engineering problems, smart design and rigorous execution make a huge difference. Tesla understood that heat management is key to an EV, so they invested in designing a compact and elegant system (Google “octovalve”) to move heat wherever it was helpful to send it. They also use intelligence to allow the car to optimize itself for charging. For example, you can use the Tesla smartphone app to have your car wake itself up and warm or cool both the battery and cabin while still plugged in. And if you use navigation to plan your charging stops, it will automatically precondition the battery pack as you are getting close for optimal charging speed. Most of the cars that performed poorly on that graph were because of shoddy engineering by people who don’t understand the problem space. That’s not a problem with EVs, it’s a problem with bad engineers and management who care about the wrong things. |
