Huawei, Which Beat Apple at Making a Car, Announces New Range-Extended EV
- zepto 5y agoBeat Apple at making a car? How do they figure that, I wonder.
- rektide 5y agoPersonally I really love the idea of a range extender engine. I want to be able to go camp or be somewhere far away & be able to recharge. I also like the idea that a range-extender engine can be tuned to efficiency, in a very narrow performance band. Let's quickly calculate efficiency here: > can generate 3.2 kWh of electricity with one liter of fuel through its 1.5T four-cylinder range extender 3.0 Gas is 46MJ/kg. * 0.2778kWh/MJ. Comes to 12.778kWh/kg. Gas weights 6lbs/gallon * 1gallon/3.78541liter * 1lb/2.205kg, = 0.719kg/l. So multiply 12.778 * 0.719, get 9.187kWh/l. Making 3.2kWh would be 34.8% efficiency from gas, if I got these figures right.
