Compared with hybrid Electric Car, Electric Car use electric motors instead of internal combustion engines, with low noise and zero pollution, and the space and time weights less occupied by motors, oil and transmission devices can be used to compensate battery requirements; and because of the use of a single electric energy source Compared with the hybrid Oil Electric Hybrid Sedan, the electronic control system is greatly simplified, which reduces the cost and can also compensate for the price of the battery part.
(1) Technical level Although domestic auto companies have responded strongly to the R&D and production of new energy vehicles, due to the limited number of models with high technical content and energy production, and the competition of pure Electric Car has begun to intensify, Due to low research and development costs and insufficient innovation capabilities, it is directly related to the technical level of Electric Car with independent intellectual property rights in my country;
(2) The "power supply" at the level of rechargeable batteries is the "technical shortcoming" of the future development of new energy vehicles. At present, there are two key problems: one is the high cost of rechargeable batteries, and the specific energy of rechargeable batteries Second, whether there will be a real industrial chain of lithium battery recycling, leasing and remanufacturing in the Electric Car market in the future; the third is the rechargeable battery socket Not the same, it seems that different brands of mobile phone charging ports are not the same, the uncertainty of the "standard" will have a great impact on the development direction of battery cars and so on.
(3) At the energy level, the investment of Oil Electric Hybrid Sedan is more expensive than that of diesel vehicles. The application of electric power projects requires the construction of power stations, power transmission and distribution equipment, power distribution equipment, smart charging stations, and battery factories;
The battery of Electric Car is the power source of Electric Car, and the motor is the "heart" of Electric Car, its importance is self-evident. The motor synchronous frequency conversion technology of Electric Car has high efficiency, less heat generation and higher cruising range; the customized Hall components are used for high temperature resistance, anti-static, moisture resistance, and can provide multiple protection and shock resistance.
High energy conversion efficiency: At the same time, it can recover the energy of the braking system and downhill, and improve the energy utilization rate; research on new energy vehicles has found that its energy utilization efficiency has surpassed that of gasoline engine vehicles. Especially in urban operation, where the vehicles stop and go, and the driving speed is not too high, Electric Car are more suitable. Electric Car do not consume electricity when they stop. In the braking system, the motor can be automatically converted into a generator set to realize energy reuse during braking and deceleration.
