Picked this up from the UK board, interesting.
There you go, 108kWh!! A number to support our wishful thinking >When charged, these cells are ~4.2 vdc, sometimes higher. 108 kWh? when taken to peak voltage?
Wow, they really had a huge buffer ... perhaps that chemistry was more susceptible to damage at high SoC?I have some LG Chem cells that have been sitting since 2013 from a junkyard Chevy Volt. They are 3.89. No idea on SOC. Chevy Volts only charge to about 68% SOC when brand new, full charge. They are 16.0 kWh with only 10.8 kWh usable.
The Volt is unlike other cars.Wow, they (the Volt) really had a huge buffer ... perhaps that chemistry was more susceptible to damage at high SoC?
I was focusing on the battery technology they used. Most Euro PHEVs are extremely short range and cannot complete all the EPA test cycles without the motor starting. But this is what the law favored. Example 2019 MB GLC350e, 0-9 miles All Electric Range, 25 mpg.The Volt is a nice piece of technology, probably the best hybrid ever, but it sold like crap because it wasn't really what people wanted. Those who have drunk the EV koolaid know how nice it is to be ICE free on a vehicle, and those who want range and efficiency every day are better off with a Prius. In the end, there just wasn't that much market. The only reason there's a plugin market in Europe is because of all the EV only laws in inner cities.
Serial hybrids have inherent power bottleneck.If you wanted 40 mpg full sized trucks and real SUV (seats 6 full sized adults or more, tows a car trailer), the only solution with today's technology and EV infrastructure would be something like the Voltec technology. Battery large enough for >75% of daily use, gas engine for interstate travel or heavy towing.
