All or part of the vehicles driven by electric motors and equipped with large-capacity electric energy storage devices are collectively referred to as
Used Car.
For Used Car, the battery is equivalent to the fuel tank in a traditional car. As long as the load is driven by electricity, the larger the battery capacity, the stronger the battery life will be. Some car companies achieve the effect of current expansion by increasing the size and number of batteries, but in terms of body structure, more batteries mean more physical space occupied, and the drag coefficient of Used Car increases by 0.01cd, The cruising range will be reduced by more than 5 kilometers, and the weight of the battery is also an important factor restricting the battery capacity.
The electronic control system is equivalent to the computer's operating system, which monitors and manages the battery of the
Used Electric Car, so that the battery can work in the best condition and maximize the performance of the battery. And a good electronic control system can not only prevent Used Car from overcharging and discharging, but also monitor the battery operating temperature at any time and adjust the battery temperature at any time to achieve the best discharge effect and other functions.
⑴ Small pollution. Used
Electric Car is essentially a zero-emission vehicle, which generally does not emit pollutants directly. Indirect pollutants are mainly produced in the process of power generation and hydrogen production of non-renewable energy. Its pollutants can be controlled by means of centralized treatment. Hybrid vehicles also have the effect of zero emissions in pure electric driving mode. At the same time, due to the reduction of fuel consumption, CO2 emissions can be reduced by more than 30%. In addition, the noise of Used Car is more than 5 decibels lower than that of similar
fuel vehicles. The large-scale promotion of Used Car will greatly reduce urban noise.
⑵, saving energy. According to estimates, the average energy utilization of traditional fuel oil from mining to vehicle utilization is only about 14%. After adopting hybrid technology, the energy utilization rate can be increased by more than 30%. Used Electric Car can use the power grid to charge in the valley at night, which improves the overall efficiency of the power grid.
⑶. Optimize energy consumption structure. At present, my country's transportation accounts for about half of the total oil consumption. Since Used Car have the characteristics of diversified energy sources, various renewable energy sources can be converted into electric energy or hydrogen energy for effective use. Charging increases the utilization of electricity in the field of transportation energy, reduces dependence on oil resources, and optimizes the composition of transportation energy.
