Those forklift around there for 60 years, their working principle depends on hydraulic power which is astonishing. They can hold incredible amount of load with relatively small power.

A Tractor works different, if tech allow to use battery for farmer machines, tractor would not be fitted with battery power first. There are machines technically consume less power than tractors.

Don't tractors also utilize add-ons that depend on hydrolics? If so then the battery would only be strained by transport of high loads. Considering Tesla has already announced full on trucks that can haul a lot more over a significantly longer distance this doesn't seem as outlandish as you present it.

Also, what field are you working in? Does it involve battery tech?

OK, lets assume that the minister actually meant "forklift" for tractor which is used for agriculture.

I checked A forklift with 5 tones capacity for reference power consumption.

It has 2 motors for drive, each 11.3 kW =22.6 kW
1 motor for lifting = 26 kW
22.6+26=48.6 kW at maximum load

Since we dont always use it at max, according to VDI cyle, its energy consumption is 17.9 kW per hour.

In a 8 hour operation= 8x17.9=143.2 kWH


Cost of 8 hour work==> 76.9 TL

7 TL is a big lie...! This tractor itself, as everything, is a big LIE...!

Your estimatation a trash MAN. What do expect a tractor all day its lifting something to open space?
Ordinary an e-tractor has 30kWh battery, that means 40 kuruş *30 =12 TL and probably the those did 7 TL estimation thought ordinary low-working load day for it.

I am an electrical engineer, today's battery tech doesnt allow a tractor for 8 hours work. it is completely lie, propaganda for election.

O pulluğu daldır bakalım toprağa 2 saate çıkabilecek mi o traktör. Öteki seçime kadar görmeyeceğiz zaten.

Edit: I just read the original news, minister says the tractor can carry 4 tons! wow! what a great tractor. 10 years old boy can carry 4 tons at plain road too(of course on trail). another AKP bull.....

Why? Can you use your electrical engineering background to explain to us why a work vehicle can not operate on electricity for 8 hours ? Electric forklift that I've ordered for warehouse operations has more than 8 hours operating span on a single charge (8hrs is average work shift). So, I'm curious how a low speed high torque electric motor that tractors would use can not operate for 8 hours.. because of existing battery tech...

i said forklift is different, it can work 8 hours may be 20 hours, a tractor is different machine. i posted above a video it shows 1,5 hp(1,2kw) can hold 15 tons. An electrical tractor would use almost all motor power against drag.

lets say 80kw tractor for 8 hours? what battery power needed? lets take a battery (İnci Akü Formul A Asia 12V 90Ah 750CCA)
size 306x175x224 mm. This battery can sustain 12x90=1080 watts for an hour(theoretically). lets say 1kw practically. How many battery need for 1 hour work---------->80 . Because we have 80kw tractor.
lets put 8 hours on it. it is 8x80=640 battery.
How much space you need.? 306x175x224x640= 7,68m3
How about weight of batteries 640x16,8kg= 10,752 tons
How much a regular tractor weight? 4 tons!

According to your math how much tesla model s is supposed to weigh with 85 kwh battery?

Your math is based on the tractor constantly requiring 80kw/h of power. Just because I drive a 255hp car doesn't mean I'm always utilizing that much power, there are dips and there are spikes- that allows me to get better economy out of my drive. Same concept translates to Electrical Vehicles, perhaps even better because there is less wastage of the energy stored.

Anyway, I've looked up electrical Tractors and I've found Fendt working on a concept with 5 hours operating time with 100kwh battery pack.

• Company: Fendt
• Name: e100 Vario
• Type: Battery-powered tractor
• Key feature: 50kW (67hp) output sustained typically for 5 hours with a 100kwh battery; 80% re-charge in 40 minutes possible; electric, hydraulic and pto implement drives

Well you sounded like a good engineer and math expert, thought you could enlighten me. Never mind.

Anyway, I've looked up electrical Tractors and I've found Fendt working on a concept with 5 hours operating time with 100kwh battery pack.

it uses 650V high capacity li-ion batteries, it is only 50kw. electricity especially in high voltage kills! make cause fire etc. that is why we never see high voltage batteries on cars.

i calculated at worst condition which an engineer must do. otherwise it would be a story like our herons endurance. They say endurance is 40hrs but we see them on flights only 12 hrs! dont trust label values. you as a smart guy can understand quickly. by the way i dont think that our new great! tractor use li-ion batteries anyway.

Well you sounded like a good engineer and math expert, thought you could enlighten me. Never mind.

well sorry man. lets think about tesla
-automobile is a light weight vehicle
-Li-ion batteries are high consantrated you can pack soo much watts, but it is expensive
-car rarely use its max power, generally lower than 1/3(my assumption), so bigger engine doesnt reflect ordinary power consumption
-when they press brake it charge batteries , that make preserve energy etc,


when i last time check tesla model-s could go for only 300km(years ago), i dont follow them anymore

I have watched a doc. about it. Tesla uses huge number of home-use-like batteries connected each other on the base of the car. Car has another feature to charge back when driving.

Found it.

1. You should first learn SI units. Lb and kg are not same things.

The lift of which you gave link to has a 1000 Lb (that is 450kg) dynamic load and 3000 Lb (1350 kg) static load capacity.

Here we are talking about 5000 kg load.

2. About working conditions/duration; i said "according to VDI CYCLE".

3. My cost calculation is taken from the electric distribution company. (i gave the link above) which means pay at the door.

I did not know German education quality was this much low...

Are these for me??
Even if it is or not. You could not understand the physics behind it. Read the link i shared above. Everything possible and it is sold abroad now.

Holography to date, the problem is thought to be solved by optical technology based on a brand new mathematical approach based on a simple engineering team in the Science Academy member Omer Ilday and #BAGEP award Onur Tokel there. This important article was the cover of Nature Photonics

There are still difficulties with the third dimension of holography, but today we are one step closer to the fact that the holodeck in Star Trek is real.
