China Construction Machinery Information

it is inevitable that transporting excavated materials near the mining site is a dirty job. However, according to the news from Swiss Federal material testing and Research Laboratory (EMPA) station on September 13, The heavy-duty electric dump truck it is developing will make this work cleaner. In the next few months, Komatsu HD truck with a weight of 45 tons and a 4.5-ton heavy battery pack will transport materials back and forth in chasseral, Switzerland, which will also become the largest electric vehicle in the world. It is worth noting that this modified prototype car can store energy through the braking energy recovery system when going downhill. Each trip, the power on the car can be increased by 10 kwh. That is to say, in theory, this truck will not consume energy during operation, but also rely on carrying goods to generate new power

it is reported that the electric vehicle under transformation is funded by a Swiss consortium, and the experts from the Swiss Federal material testing and research laboratory are responsible for its operation safety

experts refitted a heavy-duty diesel dump truck manufactured by Komatsu, Japan, and transformed it into a fully electric mine vehicle prototype. Greek graphene fiber has special functions such as antibacterial, anti mite, anti heat, anti cutting, anti-static, anti ultraviolet, far-infrared heating and conduction cooling. It is expected to transport materials in a more environmentally friendly way

the transformation involves dismantling the original diesel engine and making room for the giant battery pack. Among them, the battery pack consists of 1400 nickel manganese cobalt batteries, with a storage capacity of 700 kwh. Next, Jinan Shijin will introduce to you the basic knowledge of the frequency converter of the electronic universal testing machine. In order to solve various problems, the frequency converter of the electronic universal testing machine can install an air conditioning system. Scientists from the Swiss Federal materials testing and research laboratory and Kuhn group introduced that this will be the largest battery pack equipped for land vehicles

the modified prototype vehicle will be put into the load transportation test - 20 times a day, each time carrying a load of 65 tons down the mountain. Each time, the energy recovery device can charge the battery pack - not only enough to cope with the return uphill road, but also to return the remaining power. When going downhill, the power generation equipment will charge the battery pack with a current of up to 3000 amperes to fill it with 40 kilowatt hours of electricity, so each trip will also make a net profit of 10 kilowatt hours of electricity. The generated power can be used for no-load climbing, so the round-trip power will not be reduced

experts say that even under the worst environmental conditions, vehicles can still run on a slope with a gradient of 13%. At present, the Swiss company is conducting further tests on the vehicle

for electric vehicles, the transformation with dump trucks is a new field. Therefore, the research team will pay close attention to the performance of the modified prototype vehicle to see if it will fail. This will mean that the vehicle will undergo a battery overcharge test and check the battery's response when the nickel manganese cobalt battery is damaged with steel nails

when talking about the next generation of electric vehicles, Marcel held, an expert in the Swiss Federal materials testing and research laboratory who is not easy to degrade batteries, said that nickel manganese cobalt batteries will also be the choice of the German automotive industry

if the prototype vehicle passes all the tests, the Swiss Federal material testing and research laboratory says that 8 all electric mine vehicle prototype vehicles can be used in the cement plant at the same time. The prototype vehicle will also open up new fields for large construction machinery, such as tunnels or residential areas sensitive to exhaust gas and noise
