![]() Accelerate and decelerate constantly while trying to plow through traffic in city centers and rush hours. Also, they're used the way EVs hate most. You never want your battery to go flat in an ambulance and lose the mobility and life support at the same time. > ambulances Generally low mileage vehicles, no idea why you'd not be able to use them as EVs.īecause they are neither low mileage and the medical equipment behind needs power. They have very different energy demands, usage patterns, risk profiles, and failure modes. > For everything semi-truck and smaller, batteries have a high enough capacity to service today.įire trucks aren’t semis. Local government maintains diesel generators and a fuel supply to handle this kind of extreme infrastructure failure. How do you pump fuel if the grid is down? > And, consider this when thinking of a "grid down" situation. There is a several order-of-magnitude difference between the power required to service the station, dispatch, etc, as opposed to what’s required to rapidly recharge the kind of massive batteries an EV fire apparatus would require. Because you can't have a fire station, EMT dispatch, etc go dark because of a grid down situation. > Generators are a thing that pretty much every one of these services will have. The engine powers the apparatus itself, its pumps, and often, a huge alternator for its electrical systems, and an inverter supplying 110V for use with fans, portable lighting, etc. The truck alone weighs around 10,000-15,000 lbs, without water, and they carry anywhere from ~500 gallons of water (attack engines) to upwards of ~2600 gallons (tenders). Fire departments cannot afford to have their apparatus out-of-service for hours while they recharge. The main ones are airplanes and ships where getting power is hard and the power density needs to be high.įor everything semi-truck and smaller, batteries have a high enough capacity to service today. There are few places where EVs are bad fits. Because you can't have a fire station, EMT dispatch, etc go dark because of a grid down situation.Īnd, consider this when thinking of a "grid down" situation. Generators are a thing that pretty much every one of these services will have. > that have to be able to function for weeks at a time in a grid down situation. Perhaps the only one that would be bad given the amount of power required to tow a vehicle.Įxcellent option for EVs because they almost never haul equipment and they are always working on electrical things. ![]() Generally low mileage vehicles, no idea why you'd not be able to use them as EVs. They have super low millage and you'd not have to worry about things like stagnant fuel.
