| > I still dream of the US/EU coming up with a standardized set of chassis/engines instead of having dozens of companies independently spending millions trying to solve the same problems BYD has done that, with their E-Axle. The E-Axle has the axle, wheels, and motor. It goes with a BYD "8 in one" electronics power box and a battery. Here is their pitch to Japanese carmakers.[1] Google translated version follows. (Google Translate has become much better at Japanese lately.)
The automaker buys the E-axle, power box, and battery, plugs them together, and hooks it to the driver interface with CANbus. This approach seems to have cut the cost of BYD's cars. Other companies are now marketing E-axles for trucks.[2] Trucking has a lot of builders who start with a bare chassis and add industry-specific bodies and equipment - ambulance, tow truck, etc.
BYD itself sells light truck sized versions, and Dana sells heavy truck dual axle versions. It's quite possible that a mounting point standard will emerge for this, like NEMA motor mounts
or jet engine pylons. Then you can use different E-axle vendors. [1] https://byd.co.jp/e-life/manufacturer_stories04/ [1] https://byd-co-jp.translate.goog/e-life/manufacturer_stories... [2] https://www.trucksales.com.au/editorial/details/what-is-an-e... |
