Munro on KIA EV9
Sometimes Munro focuses on minor technical data and miss the mountain:
Two out of three ain't bad:
- Wye motor performance
- Delta motor performance
- Missed - step up/down Wye, power transformer
- Driving one Wye leg doubles the voltage on the other two.
- Driving two Wye legs halves the voltage on the other.
- Power is limited by what the motor can handle.
- Most 800-to-400 VAC converters limit the charging power . . . inefficient and expensive.
Motor performance is nice, effectively a two-stage 'tranformation' but the built-in voltage doubling is the real gem. I have long thought about a home, fast DC charger, but the cost of a 40 A , 240 VAC transformer put me off. But if I can get a salvaged KIA 9 or IONIQ 5 motor, problem solved for a fraction of the cost.
Today, my NEMA 14-15 circuit, limited to 40 A at 240 VAC, can provide 9.6 kW. But both of... -

My 2017 BMW i3-REx has traditional cruise control. At one time, it had been considered competition to AutoPilot. But things are changing:
Intel (INTC) Is Considering Options for Its Stake in Mobileye - Bloomberg
Intel Corp. is considering options for its stake in its struggling automated driving systems provider Mobileye Global Inc. as part of a major strategy overhaul, people with knowledge of the matter said. Shares of Mobileye fell to a record low.
The chipmaker could offload some of its 88% holding in Mobileye on the public market or via a sale to...
