In the United States developed a hybrid low-noise armored car eJLTV

In 2015, the American company Oshkosh won the tender for the supply of a JLTV light tactical armored vehicle for the US Armed Forces, who intend to partially replace the Humvee fleet with this vehicle. At the same time, further creation of new samples of the JLTV family is underway.

Oshkosh has taken the initiative to develop a hybrid version of the technology, which, as indicated, has a quiet ride, while “retaining all the characteristics and protection” of the basic modification. The new car received the designation eJLTV.

Virtually silent electric drive enhances the eJLTV's ability to perform reconnaissance missions without being detected

- declare in the company.

Among other advantages of the new version, fuel savings of 20% are indicated. The eJLTV lithium-ion battery stores energy while the vehicle is in use and can be fully charged in 30 minutes. As explained by Oshkosh, the self-charging capability eliminates the need for additional vehicle maintenance, which could lead to poor logistics on the battlefield.

The Army plans to complete the JLTV procurement program in the basic version and award a follow-up contract in September 2022. The planned $6,5 billion agreement provides for the delivery of an additional 15 vehicles over five years, after which new options will follow. Oshkosh is betting on the new eJLTV, thanks to which they hope to win a new contract and continue deliveries to the military.

In their desert, under each cactus, there is an outlet for auto-charging ??? Moshina may not be bad, but problems with charging in battle conditions or a long march make hybridity a minus in this case.

A hybrid is not an electric car, there is also an internal combustion engine, read about the Toyota Prius.

[Thrifty]

Air Force reserve lieutenant-read three times, I see an indication of the presence of a lithium-ion battery, which increases the operating time! A hybrid installation is ALWAYS combined, for ground transport it is most often an internal combustion engine, diesel, gas turbine engine and an electric motor! I'm not writing that this is an armored electric car, it's a trachoma with a conventional engine, a typical ugly armored car.

[bk316]

Something you are confused.
There is always a battery in a hybrid.
The battery in a hybrid can not be recharged from the outlet from the word at all.
However, you can use an electric motor.
Very useful when you need to move quietly.
Well, there is some kind of fuel economy due to recuperation, and the heavier the car, the greater the savings.


So the hybrid is a PLUS.

Well, if the issues of reliability, survivability, etc. are resolved.

The only negative is that the hybrid will always be more expensive.

[Avior]

Well, some kind of fuel economy due to recuperation

Not only. The highest fuel consumption is at the moments of acceleration - the needle of the device for measuring fuel consumption in this mode goes off scale to the right, fuel consumption increases significantly due to the enrichment of the mixture.
In a hybrid drive, the electric drive takes over the acceleration function. This significantly reduces fuel consumption and eliminates the need to drive at high speeds, reducing the overall noise of the car.

[bk316]

Yes, and it is also

[ycuce234-san]

Quote: Avior

Highest fuel consumption during acceleration

The same savings effect can also be obtained from an energy storage flywheel.
Recently there was a situation in the news "electric bus - frozen" - and with a gyrobus this would not be possible in a cold climate.

[28st region]

This is my second year with a hybrid. The car periodically spends the night in the yard. And the frosts we have oh mom all January and a piece of December did not rise above 30, below it always please reached 45 in the red .. The car surprisingly starts with a half kick. You look down on the ordinary ones who try to start every morning.
So this is normal for hybrids. And you don’t need a big battery to start the car, you can generally start it from a battery. What was shown to me in the service. Disconnected the terminals and started from a conventional battery.

[ycuce234-san]

The internal combustion engine starts up and it was also about the possibility of saving fuel, which is not limited to only one option with a battery - for example, the developers did not try to implement switchable cylinders.
In data centers, they are trying to use flywheels, not only batteries. https://www.iksmedia.ru/articles/2974544-IBP-raskruchivayut-maxovik.html

[bk316]

Yeah, it's very smart - to sit on a furiously rotating ingot under enemy fire. This is cooler than a powder keg.

[ycuce234-san]

Flywheels at least come in a low-hazard tape version, with the possibility of delayed destruction.
A lithium battery provides instant cremation - when its body is broken, the discharge current will be like that of an arc metallurgical furnace, with the appropriate temperature.
In general, it would make sense to make both fuel tanks and batteries automatically reset in an emergency, and autonomous electrical systems - de-energized. When the body is deformed, the factory locks are opened by this deformation and dangerous units are discarded by the force of inertia with the withdrawal along the guides.

[bk316]

And the lithium battery provides instant cremation -

It doesn’t provide a damn thing, all the batteries in the car are stacked from 18600 or or 21700 cells or analogues and each element with protection against short circuit and overheating in a separate housing. In addition, a group of elements is controlled by the controller and it also has protection. Learn materiel.

[ycuce234-san]

And how they burn powerfully, even with such protection. Protection, apparently, does not always help. Videos of fires are gradually starting to accumulate, with the introduction of electric ships into operation.

[bk316]

Well, yes, they burn, well, in general, so-so compared to gasoline or diesel. Anyway, no instant cremation.
Magnesium alloy burns much more strongly.

[dauria]

The only negative is that the hybrid will always be more expensive.

The only one ? How are you going to repair this fool in the war - this alone is enough to abandon this idea. What kind of noiselessness nafig? As if they were going to drive up to a pistol shot. And from half a kilometer you won’t even hear a tractor. Now you can hear a passenger car by the rustling of tires rather than by the motor.

[bk316]

And from half a kilometer you won’t even hear a tractor.

No matter how polite you are, you are probably not an artilleryman. It is not easy to hear, but you will get the coordinates.

Now you can hear a passenger car by the rustling of tires rather than by the motor.

And not a tanker, they never stood next to a tank. The article is not about a passenger car.

[bk316]

How are you going to repair this fool in the war

What is there to repair? Batteries are easy to replace.
An electric motor is much lighter than an internal combustion engine.
you probably never did not see a hybrid up close (at the service)

[28st region]

In a hybrid, the battery is never charged from an outlet or from the engine or the spinning wheels. The electric motor is used as an additional usually small power.
What is not too great is the presence of a large number of electronics.

[DrRey]

For the American military budget - more expensive - this is a plus. Can cut more

[tralflot1832]

It’s a pity that in childhood there were no lithium-ion batteries, otherwise I would have believed how they behave in a fire.

[bk316]

so I would believe how they behave in a fire

Okay, Andrey. years are useless.
I was not too lazy to check, although I was already over 50 then.
And in a fire and in water ..... and in vodka

[tralflot1832]

As a result of the experiment, the experimenter was not injured?

[bk316]

Didn't get hurt during the course. But as a result of the consumption of vodka during the experiment, he suffered a little.

[Volga073]

Just poke her with a knife! The main thing is that someone has time to take you to the hospital later ..

[den3080]

and the thought flashed through my mind that there were pedals for the crew and landing, well, as before in children's cars ...
well, that is, if necessary, then the kinetic energy is converted into electrical energy and so on ..

[Cat Alexandrovich]

I think there are pedals. But not direct drive to the wheels, but to the dynamo to recharge the batteries!

[tralflot1832]

And who pedals to charge the batteries?

[cat Rusich]

For military hand-foot Dynamo machines have been known for a long time.
For one and "extra" weight you can lose ...

[Avior]

For long marches, noiselessness is optional, as in combat.
But in reconnaissance in the immediate vicinity of the enemy, it is very useful. Moreover, the hybrid drive allows you to reduce the noise level from using the internal combustion engine as the main one.
Batteries are just expensive.

[Oleg-Monino]

It would be in our Kostroma forests and villages in winter. What the hell is a battery? What is the noiselessness? They will leave and go home to beg.

[Volga073]

In Kostroma, it is even more important - fuel oil will run out, and here you can drive another 50 km to the house ..

The machine is equipped with a motor-generator, from which it is possible to both recharge the battery and use the machine as a mobile diesel generator with a capacity of 115 kW. eJLTV is a series-parallel hybrid.

The eJLTV lithium-ion battery stores energy while the vehicle is in use and can be fully charged in 30 minutes. As explained in Oshkosh, self-charging capability eliminates the need for additional vehicle maintenance

An expensive toy will turn out, but for special purposes it is very useful.
Silence is not always needed, but there are situations when it is very useful. Moreover, there is a noticeable fuel economy.

[tralflot1832]

By the way, congratulations, the Hungarians will sell you 130 million cubic meters of gas for February, which is 40 million less gas than what Germany receives in one day through joint venture 1.

[Avior]

The Hungarians don't sell me anything. I heard that Vladimir Vladimirovich Putin spoke with pride that Gazprom sells Hungarian gas for next to nothing, 5 times cheaper than the market price.
What can you say? Hungarians know how to make money from scratch. Then, gosh, they will still sue Gazprom for overpaying, as has been the practice lately

[tralflot1832]

Gas prices will settle down by 2024-2025. And so, according to Stoltenberg, Hungary, a loyal ally of NATO, again today vetoed Ukraine's entry into some kind of cooperation commission.

[Avior]

Gas prices will settle down by 2024-2025.

Oh yes, you are a gas connoisseur!
What are you doing here, you will earn big money on the stock exchange with such skills ...

[tralflot1832]

I'll do it when I'm done with my latest project.

[knn54]

Regarding the new competition this year. The advantage of the manufacturer is the possibility of converting already produced cars of this series into hybrids.

[6erJIblu]

We are too lazy, we are on the armor ???

[tralflot1832]

Here I am sitting in an armored personnel carrier, and a full electric package Oshkoch is sneaking past along the road, does the car have only the sound of a running engine as a unmasking factor?

[riwas]

The JLTV has four versions: General Purpose, Light Armament, Heavy Armament, and Multi-Purpose Two-Door Pickup. Armored vehicles can carry from 1587,5 to 2313 kilograms of payload, depending on the configuration.

[Alexfly]

Some kind of mixture of PHEV and MHEV systems, if the first needs to be charged sometimes, then the second is not necessary.

[Zoomlion]

What does the noise of such a bandura to stealth have to do with it? Is the thermal signature no longer important or what? Or are they going to use it against the Papuans of Polynesia, who live in a primitive communal system?
