Mobile WebSiteThe A and LY hybrid cars are charged by the car charger, and the vehicle range-increasing system is superior to the charging pile. LY hybrid car charging demand is very weak.
In the right configuration, the B LY hybrid car can replace the traditional fuel car without the need for a charging pile. Moreover, the cost of purchasing a LY hybrid car in this configuration is still lower than that of a conventional fuel vehicle.
图 1 LY混动测试车结构框图
为什么LY混动车可以不需要充电设施?也就是说可以完全不需要建设充电桩。
如图1所示，设计中的LY混动车有两个充电口。一个是75KW直流快充，另外一个15KW的交流慢充可逆充电口。这两个充电口可以同时进行充电。
在有车载增程系统的情况下，75KW快速充电口可以取消。而且完全不需要直流充电桩或慢充充电桩，只需要一个15KW的插座接口，LY混动车就如家用电器一样的用电设备充电。
The following is an example to illustrate how LY hybrids do not require a charging pile at all, only as a general electrical device.
Assume that a LY hybrid car battery capacity is 20KWH. The vehicle's extended range system has a power generation capacity of 15KWe. There is 25KG gasoline on the car, and the extended-range power generation efficiency is 30%. Then, the weight of the 20KWH battery system is 160WH/KG. The total weight of the battery system is 125KG. The extension system weighs 50KG. The battery and range-increasing system has a total weight of 175KG and a total power of 110KWH. The power consumption range of 100 kilometers under different working conditions is 13~25 degrees (see the new travel media released the measured data in "7 pure electric vehicles battery life").
In the case of low-speed 100-kilometer power consumption less than 15 degrees, the vehicle range-increasing system keeps running and the battery power does not decrease. The power consumption of 100 kilometers is more than 15 degrees, and the power consumption is 20 degrees in 100 kilometers, so it needs to be charged and charged when 4 hours. It consumes 25 degrees of electricity every 100 kilometers. After 2 hours, the battery is exhausted and needs to be charged and charged. In such a use case, there is no need to charge the pile at all. In the case of electricity consumption of less than 15 degrees in 100 kilometers, the cruising range is more than 700 kilometers without intermediate charging. The power consumption per 100 kilometers is 25 degrees, and the cruising range is more than 400 kilometers. It needs to be charged for one hour in the middle parking. The LY hybrid car configured in this way can enjoy the advantages of fueling more convenient than charging piles, oil and electricity price difference, energy saving and emission reduction.
Let us look at the energy costs in this case. 20 degrees, household electricity is 0.8 yuan per degree, 25 kilograms of gasoline is about 35 liters. Press 7 yuan per liter. The total cost is 261 yuan. It is equivalent to 0.37~0.65 yuan per kilometer for different working conditions. (The low speed range has an advantage, and the high-speed section energy cost will be higher than the traditional fuel vehicle)
At present, the battery system of the 20-degree capacity of the battery in Ningde era can be as low as 24,000 yuan. The cost of an extended range system using a motorcycle engine will not exceed 6,000 yuan. The cost of such a vehicle-mounted energy composite system is about 30,000 yuan.
In addition, the LY hybrid car has higher thermal efficiency when using an external engine to generate electricity, and the generated electric energy can be fed back to the grid. You can also charge another LY hybrid car directly. at this time. The LY hybrid car is a charging pile that can be moved.
ou should understand this through an easy-to-understand example. LY hybrid car can completely replace the traditional fuel car concept without relying on charging facilities!
G-making on paper G: The development of LY hybrid cars does not require the construction of charging piles - 28 of the liquid liquid.
The author introduces: lightyear, engaged in biomass power generation R & D design work, electrical automation major undergraduate. First of all, it is proposed to combine electric vehicles, biomass and solar energy to form a new energy utilization system. The idea proposed by lightyear is currently not recognized, and only one person can find ways to achieve these ideas.
Discussion on the content of this article:
Question 1: The LY hybrid car written here is an extended range car. Especially in the case of the car 15KWe extended range system, 20KWH battery power. Regardless of fast charging, only slow charging and fuel generation are used. Many models of this model are not competitive in the market. Does the author have a different way of writing?
A: Indeed, the LY hybrid car is an extended range vehicle in the case of a vehicle extended range system. However, such an extended range vehicle is essentially different from all previous extended range vehicles. The biggest difference is the weight reduction of the extended range system and the on-demand matching of the vehicle power. By reducing the weighting system, adults can easily transport, install, and disassemble the extended range system. When the owner travels at a short distance, the extension system can be omitted, the vehicle is also lighter, the vehicle power consumption is reduced, and the mileage is increased. When the distance traveled by the owner exceeds the pure electric mileage, only the ultra-high energy density extended range system needs to be installed in the vehicle as a backup power source. Parking can also be used as a charging post.
Question 2: Before the extended range vehicles on the market, such as the GA5 Extended Range Edition, the BMW i5 Extended Range, the cost of bicycle purchase for the Universal Extended Range Vehicle is very high. How can LY hybrid cars be able to achieve lower cost than fuel vehicles?
A: The extended range car that has been listed has both an extended range system and a large capacity battery pack. These two energy storage components are very costly. The LY hybrid car sold to the owner is a small battery pack with a battery pack capacity of 10~50 degrees. The cost of the battery pack can be recovered by the difference between the oil and electricity price in the 200-100,000-km pure electric mileage. Without an extended range system, the extended range system is rented on demand. Under this arrangement, only the conventional vehicle fuel vehicle with the same vehicle body cost must be calculated.
Question 3: Is the fuel cost of the LY hybrid car higher than that of the conventional fuel car? If so, then who would use such a LY hybrid car.
A: The fuel cost is high. The cost of 2~3.3 yuan per kWh is estimated according to different oil prices. According to the 100-kilometer of 13~25 kWh, the fuel consumption per kilometer is 0.26~0.825 yuan per kilometer. Especially in the high-speed kilometers, the efficiency of the extended-range vehicles is lower than that of the traditional fuel vehicles. There is such a fact. This is related to the efficiency of the extended range system (for related analysis, see the series of articles on the paper. The H:LY hybrid car constitutes the microgrid, which is a new distributed energy source - the twenty-nine of the liquid liquid).
However, in the case of timely charging of the vehicle battery, the comprehensive energy consumption cost of the oil and electricity will be lower than the traditional fuel. For example: When the battery power is 20KWH and the engine is 15KWe, the power consumption is 25 degrees and 100 kilometers. It can walk 200 kilometers and the speed is between 90 and 150 kilometers per hour. The average speed is 100 kilometers. The LY hybrid car was quickly charged with 80KW DC for 15 minutes immediately after 2 hours. You can be sure that you don't delay your journey and time. Under such circumstances, the overall cost of oil and electricity is still lower than that of conventional fuel vehicles.
