In order to popularize the application in any industry, it is essential to continuously reduce the cost. This is especially true for photovoltaic enterprises that are still in the cold winter. Photovoltaic power generation was once very expensive, but driven by economies of scale, the cost of photovoltaic power generation has been declining in recent years, and now it is very close to parity. All this depends on the continuous innovation of photovoltaic technology. Theoretically, a 1 square meter sunlight exposure surface can generate 1000 watts of energy at most. If you want to increase the total reception of existing solar panels, you must focus the light, which will cause the panel to burn out due to excessive temperature.

Charging or changing? It is difficult to break through the pain points of the construction of power exchange stations: the construction speed of power exchange stations is amazing. From August 2019 to December 2020, the number of power exchange stations has increased from 245 to 734 in more than a year. The top three operators are respectively Aodong, Weilai and Botan, 286, 175 and 94. The electric vehicle power change mode refers to the centralized storage, charging and distribution of a large number of batteries through a centralized charging station, and the battery replacement service for electric vehicles in the battery distribution station or the integration of battery charging, logistics allocation and power change services. However, the pain point of the power exchange mode is still the bottleneck that is difficult to break through.

The increase of power battery capacity of new energy vehicles: the fast charging performance of the power battery determines the ceiling of the fast charging pile. The development of DC fast charging pile requires the cooperation of the power battery. At present, battery manufacturers such as Ningde Times and BYD are trying to improve the energy density of batteries to enhance the endurance. In 2020, the energy density of new pure electric passenger vehicles has basically exceeded 150Wh/kg, and the average endurance mileage has exceeded 400km. The improvement of the endurance mileage of new energy vehicles has improved the practicability of high-power DC public piles, and accelerated the preference of vehicle owners for DC piles, which is the key reason why DC piles will become the choice direction of public piles in the future.

Small electric vehicles are different from traditional gasoline vehicles. What should we pay attention to during maintenance? For electric vehicles, the battery acts as its "heart", controlling the forward power of the vehicle. Especially in the charging process, we need to pay special attention! Common sense of electric vehicle charging: batteries should not be overcharged or discharged too much: overcharge and discharge of batteries will reduce their service life. Overcharging will cause the battery to heat up, which may cause spontaneous combustion, explosion and other hazards in serious cases. While driving, if the electricity meter indicates the red light area, the driver needs to stop running and charge as soon as possible, otherwise the battery loss rate will greatly increase in the long run. It is understood that the average charging time of the general battery is about 10 hours. The charging time should be well controlled. If the battery temperature exceeds 65 degrees, the charging should be stopped.
