“As winter goes and spring comes, there are good times every year.，To bid farewell to the old year and usher in the new”，January 5, 2023，At“Pack light and look brand new”At the 2023 Annual Business Conference of Hanma Science and Technology Group，Xingma Automobile has launched 2023 Xingma.M7 Light Cavalry Concrete Mixer，This car uses what is now rare in the industry.“Electric top”，Let's see what advantages it has.。
，Duration 04:01
We all know the traditional concrete mixer Truck.，Is to use a power take-off、Hydraulic system、The motor drives the reducer to operate the mixing tank，And XingmaMThe 7 Light Cavalry's electric top replaces this design.，Power is provided for the upper stirring tank by the power battery bin，Realize the cutting of the upper part and the engine power，At the same time, it adopts modular design.，The structure is compact and simplified，High transmission efficiency and reduced weight and failure rate。
XingmaM7 The electric top is used.“The motor is directly connected with the tank body”The design of，That is to say, the drive motor is directly connected to the reducer interface.，The motor is rated at 30kW，Peak power 60kW，This design not only has higher transmission efficiency,，Match it“Flexible start”Technology，And the rotation of the stirring tank can be more uniform.，Improve the quality of mixing。
On the other side of the Vehicle，It's an electric top.“Powe battery backpack with integrated design”，Its design can be said to be the essence of the electric top.。Its interior contains not only high-rate lithium batteries and high-voltage air conditioners.，It also has an overhead Generator.。
First of all, the capacity of its high-rate lithium battery is 7.Three degrees、Charge and discharge rate 5C，There are two advantages.：The first standby time is long，Can work for 3 hours without air conditioning，It can work for 2 hours with the air conditioner on；Second, long service life，The power battery is cooled by air conditioning refrigerant.，It can also keep the working temperature of the battery constant at about 25 degrees Celsius in hot summer weather.，Battery attenuation can be significantly delayed。
Followed by 4.5kWHigh-voltage electric air conditioner with large refrigerating capacity，It has three advantages.，First, it is an integrated design and installation of chassis.，The leakage caused by the modification of the overhead air conditioner of the cab is eliminated.、Security risk；Second, because it draws power directly from the battery.，Does not consume the fuel of the original Vehicles；Third, compared with the mechanical air conditioning of traditional oil vehicles,，It responds faster.、The cooling speed is fast。
Finally, the upper Generator.，It is rated at 30kW，When the battery level is below 30%Time，Rapid power generation for 5 minutes can make the stirring tank work for two hours.，And the battery pack also has an energy recovery system.，When the vehicle is going downhill、Slow down、Continuous energy supplement during taxiing。
Operating system section at the rear of the can body，It is the patented technology of Xingma Automobile.——“Welcome type electric control operating handle”，It retains the operating habits and logic of the traditional mechanical handle.，Can not only solve that problem of frequent operation of the electric control box,、High failure rate，It also allows the operator to get started quickly.、Simple operation，Make work easier。
From the overall configuration layout，We can feel the new Xingma.M7 has indeed been designed with great care.，And the technology is very high.，So what kind of advantages can such a high-equipped electric top bring us?？
One、Save fuel
That, of course, is cost saving.！The first is to save fuel.，The traditional mixer truck needs to rely on the power of the engine to drive the mixing tank to run.。And XingmaMThe electric top of 7 realizes the cutting of top and engine power.，Loading on vehicles、Transportation、Unloading、During the whole process of returning to the factory，They all use batteries.，Therefore, it can greatly reduce the fuel consumption of the vehicle.。
To test real fuel consumption and data，Xingma Automobile has officially carried out“Back to back”Real vehicle loading operation experiment，The synchronous test data of the two vehicles in the first stage are as follows:：The running mileage is 3000km，The fuel consumption of traditional fuel vehicles is 49 liters per 100 kilometers.，The fuel consumption of the electric top is 40 per hundred kilometers.2 liters，The comprehensive fuel saving rate of the electric top reaches 18%。
Because of the limited mileage of the first phase of testing.，At the same time, the transportation condition is pumping when arriving at the construction site.、Short feeding time，If it is facing the material, the time will be longer.、Conditions with longer pumping times，The fuel-saving effect will be more prominent.，Up to 30% fuel savings%。At present, the official of Xingma Automobile is conducting the second phase of fuel consumption test.。
Two、And that urea cost is save
If according to urea and fuel consumption 1：8 to calculate，The unit price of urea is 3 yuan./kg，The cost of traditional hydraulic mixer urea is about 9187 yuan./Year，The urea cost of the electric mixer truck is about 7533 yuan./Year，The annual cost of urea is saved by 1654 yuan.。
Three、Save maintenance and repair cost
The electric top-loading mixer truck can reduce the working time of the engine by more than half，First of all, the service life of post-treatment is increased by 30%-50%，Reduce maintenance times by about half，Prolong the service life of the whole vehicle，The annual maintenance cost is about 4500 yuan.。
Secondly, the top is electrified.“Energy recovery”Function，When the vehicle is going downhill and braking，Provide auxiliary braking force for the vehicle，The brake shoe can be reduced by 20%Wear and tear，Save 300 yuan in maintenance and replacement cost，It also saves the cost of 600 yuan for replacing hydraulic oil and filter element on hydraulic pressure.。
As per current 18%Fuel saving efficiency，If each mixer runs an average of 50000 per year.km，Calculation of traditional hydraulic mixer with capacity of 49L/100km，Save 4410 litres of diesel a year，According to the diesel price of 8 yuan/Liter calculation，Plus urea savings、Maintenance and repair savings，It can save about 42300 yuan a year.。
In this way，An electric top-loading mixer truck，Calculated over a 5-year life cycle，Save 21% in 5 years.150,000 yuan！It can be said that such an electric mixing tank，It's a piggy bank.。
In terms of power system，XingmaM7 used“Hanma Power”Engine，Meet China VI emission standard。Its 7.56 liters of displacement，Rated power is 257kW（350 horsepower），The peak torque of the engine is 1400 N.Nm。
Different from traditional hydraulic mixer，The engine not only needs to provide vehicle driving power,，It is also necessary to provide driving power for the top.，Lack of power when climbing a hill。Xingma with new electric topM7 Decouple the engine from the upper part，Allow the engine to focus on vehicle operation，Can effectively improve the dynamic performance of the vehicle under the same working condition，Climbing is more powerful。
At the same time，Loading on vehicles、Waiting for materials、When discharging，Xingma with electric topM7 can completely shut down the engine，Significantly reduce vehicle noise during operation。Tested in practice，Work on the electric top、With the engine off，Noise in vehicle cab is less than 42.6db，Noise outside the cab is less than 55db，Only a slight whine of the motor can be heard，It can not only reduce complaints about noise disturbance at construction sites,，But also can effectively protect the health of the driver.，It can be said to kill many birds with one stone。
The most important configuration of the cab，It is an integrated central control screen.，It's safe、Intelligence、Netcom、It can be said that the monitoring and management of the top is comprehensive.。
First of all, it has a four-way image function.，It can monitor the whole body of the vehicle in real time through the display screen.，In the scene where the mixer truck often goes in and out of the narrow construction site.，It can greatly improve the safety of vehicle operation.，At the same time, it can protect the safety of the surrounding staff.；And XingmaM7 Radar monitoring is also optional.，At night、Camera operation may be disturbed in foggy weather，Having radar can provide us with timely“Obstacle alert”，Further improve driving safety。
XingmaMThe mixer truck also has the specialization of patented technology.、Intelligent、Networked Intelligent Operation Management Platform，Get through the electrification of the topT-box、And chassisT-boxAnd the integrated control technology of the central control screen，Can realize that transport and loading state of the tank body of the mix truck、Torque、Working time of the tank、Motor and Generator status、Power battery status and other information collection functions，Make driving more intelligent。
