Cold temps: only where it’s cold, can be mitigated through design, mostly only affects range. Diesel ceases to be liquid at cold temperatures, and much engineering has gone into making it and engines that run on it viable in cold weather. Most EV manufacturers have already figured out decent civilian tech solutions to this problem for EVs.
rough usage: EV’s have less moving parts, less fluids, can have their parts better sealed against the environment (less need for air cooling overall) and don’t “breathe” oxygen like ICE do. It’s a lot easier to ruggedize things that move less, and low weight doesn’t seem to be a high priority for most military vehicles.
low infrastructure: Logistics wins wars, this is a problem for gas vehicles too, and you either have the supply lines you need, or you don’t. EV’s make a lot more sense for operations within range of a base, obviously, but a base that can make its own power (either solar or nuclear) that fuels its defensive and patrol vehicles without an oil supply would be slightly more self sufficient. (Which is moot anyway, because humans need food). The military already contends with vulnerable infrastructure as well. This is an example of how fuel (and water) is often stored on US bases.
Water immersion: Yeah, combustion engines hate this too. Motors and battery packs can be sealed, an engine cannot be since it needs to consume air to function.
Also stealthy af and much much higher torque ratios.
Only problem is current SOP for technical vehicles in most modern a armies is to be run and used continuously for days on end without contact with supply lines. If they can create E-Jerry Can modular batteries and some sort of mobile generator refueler then hell yeah. Otherwise liquids strapped to the side of everything is gonna be more effective.
We’ve already established that weight isn’t really an issue so let’s just give it two battery racks. It runs off one battery at a time so the other one can be disconnected and changed. When the one in use runs low, throw the breaker over and either change the dead battery or keep running on the aux until that one dies too if you’re in an emergency situation.
Larger vehicles with higher power requirements can scale up the number of battery racks they have and still use the universal Grunt Power Brick just in larger quantities, and you can create a battery hauler with a generator and like 40 battery slots to carry around your fresh ones and recharge your empties. That generator might be the one thing in your squadron that still runs on gasoline, supplemented with solar.
There’s no such thing as needing to disconnect while charging, unless you literally leave the battery behind somewhere. If you have two batteries on board, then you can use them in parallel.
Yes but this way you can hot swap in a fully charged battery from your carrier unit without needing to power down the vehicle. You could use both batteries in parallel, but the proposed solution minimizes charging time on any given machine by sourcing it all out to the carrier and allowing constant uptime of the target vehicle by never leaving it with two dead batteries.
Low thermal emissions makes hiding from IR much easier. Also, since there isn’t exhaust, water immersion would be much easier. But weight and range would be the most difficult. Probably favors hybrids over full EV.
Don’t diss my beloved 2 strokes like that, it’s probably some cheapo electric cart that has battery life of 7 minutes
EVs actually make a lot of sense on a battlefield, to be fair.
In what way? I could see the volume being a plus. but cold temps, rough usage, low infrastructure, water immersion all seen very concerning.

Like the Abrams X, for example.
Quiet and no IR signature. Run electronics for days or weeks without generating IR signatures.
I’m not familiar with an ev that could replace a gas/diesel truck and be used for weeks I’m a similar fashion. That’d be cool though!
Beloved 2 stroke? This shit engine design might as well be called cancer-generator with the amount of oil it burns
Seriously, some are so bad you could probably use their exhaust as fuel with a little work.
Hmm, afterburner for 2-stroke engines 🤔
