General in the USA: Military equipment on electric drive will soon compete with equipment on hydrocarbon fuel on the battlefield

In the United States, a program is presented to put into service army vehicles and armored vehicles equipped with electric motors. The Pentagon says that such a program reflects a general concept according to which the latest military equipment of the US Army "will be less dependent on fossil fuels."

Electric vehicles in the American army still exist today, but these are rather isolated cases. Moreover, such vehicles are not combat vehicles.
The new program involves the creation of electric vehicles that could be used in combat operations. It is reported that the implemented requirements imply an increase in the number of tactical advantages, including the power reserve.

From concept:

... the possibility is underway to double the duration of the use of electrically powered vehicles in combat operations, to reduce the noise level, as well as to reduce the logistical burden, including the need for hydrocarbon fuel supplies.

US Army Lieutenant General Eric Wesley:

We are focused not only on equipping military equipment with electric motors, but also on how an entire enterprise can operate to maintain a fleet of such equipment in good condition.

General Wesley believes that the day is not far off when electric-powered military equipment will seriously compete with hydrocarbon-powered equipment, including on the battlefield.

Wesley:

We are now exploring the possibility of implementing this approach, studying aspects of the new program.

With the compact YSU it is possible

Probably.
Electrical engineering with a 300 km range and quick-change battery cells.
The convoy has a supply of batteries.
At the YSU department with a loading machine.

It may well be more profitable than hydrocarbons.

[hrych]

There is a tractor circuit where a generator works, and electric motors drive the tracks. In theory, a battery instead of a generator and hello. However, the battery is not a source of eternal energy, it only accumulates it from the same diesel generators, from power grids, which are mainly on hydrocarbons, well, there are hydroelectric power plants, nuclear power plants, etc. Therefore, it is nonsense to have a diesel generator charging the battery, when this hydrocarbon directly goes to the engine without losses ... Here is a certain prospect from the small nuclear power plant that charges everyone. But again, combat stability suffers. Smack her and sailed ... all.

If you smash a small nuclear power plant in the location of the unit, then the whole area will be dangerous from radioactive contamination. Well, the technique will stop. From the point of view of combat stability, such a scheme is about nothing. Rather, there will be a gas turbine power plant on a charge, and not one ... By the way, do the military think that batteries of SUCH capacity will be less dangerous if damaged in battle than a tank with diesel fuel? In vain, in vain ...

Yeah, target number one. He put one car out of action, the whole squad was left without a move. Either thing threw a spare canister into the trunk and you don't depend on anyone. There is no doubt, sooner or later, maybe this will happen, everyone will switch to electric vehicles. But with the current technical structure, when the entire electromobility economy depends on infrastructure, this is a very big problem, practically insoluble. So, while this is the lot of science fiction writers. As they say, dreaming is not harmful.

[Same lech]

I hardly believe that the electric drive will withstand the impact of an artillery shell on the body of the car ... it will shake so that all the windings and brushes will fly out of their nests.
And if the battery or generator is damaged, then the shvak business ... you will have to leave the equipment on the battlefield as scrap metal.

[hrych]

So actually the problem with EMP. And start the diesel engine and try to stop it. Such Americans are kind futurists, and these Russians with their Krasukha or Rubella yes with an EMP tool, not to mention the damaging factors of a vigorous bonba.

Yes, no, they have a full-blown Musk with his Tesla. We practiced on a passenger car, sent it towards Mars and Teslo tanks dreamed of. By the way, these capacious lithium batteries are also explosives. And so it is clear, it began with cellular, when cadmium pushed out, then quadcopters, then a car and the Japanese already with a submarine. Of course, they decided to cripple the armored vehicles.

EMP, which will burn the motor windings, can only be from an atomic bomb, and even then it is unlikely. But even without engines, modern technology has enough all kinds of electric drives, not to mention electronics. So your remark is meaningless.

[hrych]

Firstly, the tank, at least ours, can work without electronics and wires at all. The engine is started by the launcher, you can try it "crooked" The gun and transmission are all mechanics, and the optical sight has not been canceled. Therefore, even with an EMP of a nuclear explosion, our tank remains a combat unit, and it also perfectly protects the crew from all factors. Therefore, my remark is not devoid of meaning.

[astepanov]

Yes, a tank without communication, navigation, electric drives, ventilation system ... Are you describing the coffin, or what?

Hello, how did you fight in the Second World War? The radio stations did not appear immediately and nothing, the combat mission was carried out. Everything is clear with you, without a navigator you are fucked

And without a shell it will not survive. You can ride it on the prairies, but in the mountains, in swamps, and at minus 30 temperatures, it will die at once. And the charging trucks should be nearby, the power reserve is very small. I judge at this time on the buses "Volvo-hybrid" which has both an engine and an electric motor. And they have not yet invented a battery that will be as big as a car battery and have a capacity of at least 100 km. move, and navryatli will invent.

They will never invent. All anode materials with decent energy are located in the first groups and the first periods of the periodic system: they are hydrogen, lithium, sodium, magnesium, aluminum, calcium. Cathode materials - oxygen (preferably from air), sulfur, some complex compounds (very few). Alcohols and hydrocarbons can be added to the anodic ones, maybe - hydrides of lithium, sodium, magnesium and boron, and their complexes. That's the whole list, and you can't argue against thermodynamics. There are unshakable things: out of three segments, you can add only one closed figure - a triangle, this is how it was before and will be so in a thousand years, no matter how science develops. A car needs 12 kWh per 100 tonne-kilometers of track in a standard urban cycle, and you will never be able to cram them into the volume of a regular battery.

Quote: The same LYOKHA

Yeah. They will replace it right now. By the way, a nuclear battery for a car must have a capacity of at least half a hundred horses (which is about 36 kW), but a nuclear battery, unlike a battery, works all the time. Where will you put the energy in the parking lot? The battery will melt! And one more thing: the efficiency of a nuclear (more precisely, an isotope) battery cannot be higher than 50%. Again, the question arises: where to divert 72 kW of thermal power? And can you imagine what danger a source with such a radiation power has?

Quote: voyaka uh

But the hydrogen circuit has a power saving benefit

What do you have in mind? Electricity consumption is determined by the power of the engine, not by the design of the battery. The main problem with hydrogen fuel cells is the difficulty in storing hydrogen. In a cylinder with a volume of 22,4 liters at a pressure of 500 atmospheres, you can store only 1 kg of hydrogen, and in a tank of the same volume, 18 kg of gasoline or diesel fuel can be stored. The efficiency of fuel cells is not very high, so there will be no benefit in terms of mileage, and even in terms of money - at all. And the price of a fuel cell is enormous.

[Mikhail m]

Quote: tihonmarine

at minus 30 temperature, it will die at once

A sharp loss of capacity at negative temperatures is one problem. The second, under the same circumstances, is the need to heat at least the habitable space. If the internal combustion engine uses excess heat for this, then there are only batteries for the electric tank. And how many kilowatts are needed to warm up a multi-ton piece of iron ... So moving away from the outlet is very fraught.

electric drives in technology are complete, of various types, mostly not of great size. Making solid is not a problem. But with the "battery" everything is much more complicated, i.e. now nothing good and nothing.

[Stalllker]

You might think that after an artillery shell hits the body of machines with internal combustion engines, the valves and nozzles will remain in place. Yes, after 122 landmines to collect in both cases, there will be nothing

And this applies to ARMATA. And, besides, there are observation and aiming displays.

This is not the problem. The highest energy density is achieved with lithium-sulfur batteries: 0,5 kWh / kg. For diesel fuel or kerosene, taking into account the efficiency of the engine, the energy density is 3 kWh / kg, i.e. 6 times higher. it should be taken into account that so far the only use of lithium-sulfur batteries is on super-high-altitude reconnaissance aircraft, slug-boats with an ultralight wing and recharging from solar batteries, flying at altitudes of up to 20 km or more. Several pieces have been made. These aircraft have very gentle mechanical stresses, and the elements can be made with film hulls. On military equipment, both vibrations and shocks will require powerful housings that will reduce the performance of the batteries. The second problem is the low power of the Li-S. 0,5 kWh / kg is obtained with a ten-hour discharge, and already with a two-hour discharge it is halved. Finally, flammability, explosiveness, low resource ...
Further, whichever battery you take, you need to charge it. This means that you need to carry a diesel generator (or rather a lot of diesel generators), to bring diesel fuel for their work ... What is the gain?
The situation could be saved by fuel cells, but they have low power and huge cost. Moreover, the best of them, which run on hydrogen, are hardly suitable for the military - it is very difficult to store hydrogen. With other cathode materials (hydrazine, alcohols, hydrocarbons), fuel cells cope poorly.
In my opinion, hybrid drives have the greatest prospects in military technology, which can actually reduce fuel consumption by about 30% and ensure not very distant covert movement on electric traction. They do not need to be recharged from an external power supply.

[mat-vey]

and also to reduce the logistical burden, including the need for hydrocarbon fuel supplies.

And the electricity for the batteries will be transmitted by X-rays through the etheric matter? Well, about the "useful" additional weight on military equipment has already been discussed so much ...

That's right - the tank still has to get to this battlefield. And since teleportators have not yet been invented, there is only one way out: to a long distance - a combined march, to a near - on its own. On trawls in wartime on the road of the army rear, I would not count.
What's happened small resource The Great Patriotic War showed well - a tank does not live long in battle on average, but it marchs a lot before the battle:

During the march, 100-150 km. in three mechanized corps, due to technical malfunctions, 270 tanks were repaired.
In one of the Armies, up to 100 tanks were damaged by diesels; after the marches on the Stalingrad and Voronezh front, malfunctions in buildings of 25-30 tanks failed.
