Solid State Batteries - the future?

Solid State Battery article

This looks interesting. If one camps usually with hookups, it would be nice to have a TOAD that is carbon emissions free. The downside that I see is that energy is not free. If you look at the watt-hours of energy used by the vehicle, that is how many watt-hours would need to be put back. One horsepower equals about 745 watts. Discounting peak loading such as accelerating, which might consume 150 horsepower, cruising can probably be maintained with 50 horsepower or 37250 watts. A six hour drive, covering 350 miles, would drain 223,500 watt-hours. Using 120 volts at 30 amps, that is 3600 watts. It would require more than 60 hours of charging at 30 amps from a pedestal to recharge the battery from that 6 hour drive. So, for each hour of driving we would need 10 hours of recharging.

IMO electric car will not be a 'replacement' car till one can re-charge them in under 1 minute. All the tech in the world will not change anybodies mind if they con only goes a few hundred miles then be stopped for hours to move any further.

Glen, the article says they are looking at a potential range of 500 miles. That is appealing, and commercial charging stations using higher voltages can shorten charge times pretty dramatically, but never to your 1 minute value.

To Glen: It doesn't take anywhere near 50 hp to keep a small to medium car moving, so your energy consumption estimate and charging time is too high by a factor of 2 to 5 (depends on the car size and weight). But, many electric cars can be charged from a 240VAC, 50 amp socket, which supplies over 3 times the power, cutting the charge time by to 1/3 rd of the 120VAC/30 Amp rate.

To Colddog: not even gasoline cars "recharge" in one minute! Current electric cars have a 200+ mile ranges, plenty for the daily driver that commutes less than 1.5 hours each way, and far more than most of the trips people make, unless they are on vacation. Depending on the car and charger, you can recharge significantly in less than an hour, not hours.

For me, only a 500 mile range would make sense. We frequently travel I-5 from L.A. to Marin County (about 420 miles) to visit family, stopping at Harris Ranch for lunch as it is exactly half way. Whenever we pull in there, the entire line of charging stations is full up. I’ll stay with hybrids until the miracle battery comes along. - Jon

We are currently in Atascadero visiting family. There is a Tesla charging station which I always like to monitor when here. The first few years it was here, seeing a Tesla actually charging there was infrequent. I noticed this trip it was nearly full. Mostly model 3’s, I think.

A standard gas pump in the US is limited to 10 gallons a minute, 40 gallons a minute from commercial trucks pumps. Our LD tanks can be filled in 5 minutes from empty. 50 gallons at about 8 MPG equals 400 or so miles in the tank.

Without going to very deep in the weeds - I agree electric motors have all sort of advantages of other motors. After all all trains run on electric motors but they carry diesel generators to power them.

"After all, all trains run on electric motors but they carry diesel generators to power them."

You can exclude BART (Bay Area Rapid Transit) from that, and no doubt others. Each car has four axels that are powered by an electric motor which receives it's energy from a 3rd rail carrying 1,000vdc and collectively draws nearly 600 amps.

Put that under your frame and smoke it!

OK all heavy rail trains use diesel generators to power them ......

The plug in hybrids , such as my 2017 Volt, have been over looked to some degree. Many people, like myself, can be on battery power only most of the time. With the battery depleted it comes a hybrid. There are now about a dozen or so plug in hybrids available although the electric range varies considerably. I get up to 70 miles under ideal conditions. GM did a good job of designing it but made no serious effort to market it. It's still a "mystery" car to most people. Frank
