Some things that EV owners don’t need to deal with 1) REplacement lead acid batteries (0 vs. 1 every 3-4 years) 2) Frequent brake service (100k brake life vs. 40k) 3) Alternator replacement (0 vs. once in 200k) 4) Starter replacement (0 vs. once in 200k) 5) oil service (0 vs. 4x a year/3000...

Sometimes when discussing EVs we get passionate about them, and bring up the topic of climate change to justify the claim that anything that man can do to control climate change, we should be doing. Some of it may be worth doing, and I’ve done some of the things that are worth doing. 7.5 kW on...

I know about the regulation. It’s actually a disappointment to lose the quiet operation of the car. I like the absence of noise. Though I do understand its need. So as long as I’ve got an external speaker... lets do more with it. Biggest Bluetooth speaker for your iPhone you’ve ever seen? And...

The R1T weighs in by spec at 7250 lb (3288 kg). At 45 mph (72 kph, 20 m/s), there is 0.5 * 3288 * 20^2 = 657 kJ (1J = 1 kg m^2/s^2) or about 182 Watt-hours (1 WH = 3.6 kJ) of kinetic energy in the moving truck. We approximate energy consumption of the truck at 450 WH per mile at 45 mph...

So my venerable old Prius has regenerative braking... and I learned a few things about using them, and how to evaluate them. Regen has its biggest use in city stop-and-go driving, where your speed constantly fluctuates between 0 and some modest speed of 45 miles an hour or so. You are constantly...

So in the early days of Hybrids (2001/2002), we Prius owners used to think about how to create a slow speed sound effect as a safety function, so when the cars operated on pure electric, unwary pedestrians were made a little safer. We used to speculate about favorite sound effect. Mine in order...
