> the Hyundai Kona Electric is absurdly complicated. More than five separate CAN buses, ten or more kilograms of low voltage wiring, probably over one hundred electronic modules (most with their own CPU and firmware), etc.
This is just sad for electric cars.
- cdmckay 2y agoWhy is it sad?
- ActorNightly 2y agoCause electric cars are supposed to be simple.
- holoduke 2y agoHow would you do it otherwise? And btw. Ice cars have probably similar amount of modules.
- ActorNightly 2y agoICE cars are more complex. You want an ECU and TCU separate because those are pretty critical to the cars not breaking, you have a separate system for 12v power to the battery and accessories, you want your steering gauge cluster/display separate so it can show critical information apart from the entertainment cluster, and so on. With an electric car, the control of the motor is DEAD simple, and you already have your electrical power. You really need like 2 modules/computers at most. Motor controller that takes DC power and converts it to the phase power to drive the motor, and the "main" computer that includes a PDU and manages the systems of the car. Optionally a 3d entertainment cluster, but honestly, you can just include a slot for a tablet with a USBc plug from the main computer, and an app, and that would be better than whatever manufacturers are doing now.
