45e rescues Tesla

Since there was no way to charge the Tesla quickly enough to get to safety before freezing, Kyle came up with the idea to tow the EV with his PHEV.

But actually this article highlights how Tesla can easily regen even when being towed!

Yeah, I was surprised by how easy it was to regen. Do you think they were going downhill?

The article i read mentioned there was some downhill that helped additional regen

This highlights my exact concern with a full EV vehicle. Edge case….long road trip, chargepoints are scarce, a bit of bad luck that the one he found was inoperable, range is reduced due to cold weather and whammo, you're stuck.

Lucky he got the tow…but even so, what a pain in the neck to go through all of that when an ICE or PHEV vehicle could have simply hit the gas pump.

No doubt electric is the future, but the charging network has a ways to go before I'll trust a full EV for a long trip.

I'd add that charging stations will be down when, say, a storm breaks down the power grid. That has happened recently to Texas. If one must escape a natural disaster, both ICE and EV cars will face challenges, e.g., traffic jams, but an ICE car has a better chance.

Very clever thinking to get the Tesla moving again on its own power.

I'm a bit worried about the 45e: What happens if you have to stop for a longer period of time because of an accident, road work, bad driving conditions, waiting for a ferry or something and the HV battery runs out? That's not a problem with an ICE car as long as you have fuel (and the consumption is very low when idling), but with the 45e, I don't think it helps no matter how much fuel you have left.

I was once waiting for a tunnel to be opened, but had to turn back and take a ferry - which left after a 2-3 hours wait. I switched off the car and sat in the cold to avoid running our of electricity. Luckily, it wasn't winter yet.

I don't think you can charge the HV battery at standstill and if the ICE heat is not used to heat the cabin.. you don't want to stop for too long with the 45e.

Once the HV battery drops to a certain level, it will engage the ICE if you're still in READY mode, so as long as you have fuel, the engine will provide enough electricity to keep the cabin warm. The problem is, if you shut off when the battery is low enough, you won't get heat when you first start up until the engine can build back some level of charge.

Are you sure that the HV battery can be charged while the car isn't moving? If it can, then there's "no" problem. I just haven't seen any confirmation about this.

Eventually infrastructure will improve. There are also mobile or portable batteries developed that can be delivered to an incapacitated vehicle similar to AAA bringing a gas can. More EVs will likely get vehicle to vehicle charging in the future as well.

The electric motor sits just behind the engine and there are clutches that allow the EV motor and/or the main motor to drive the vehicle, with the transmission sitting on the output. So, the motor running at least could cause the EV motor to turn, which doubles as the generator in the 45e.

So, I've not tried this explicitly.
