The power is directly taken from the low-voltage lighting circuit. The charging power is small, and the power is supplied by the 220v/16a standard grid power supply. The typical charging time is 8 ~ 10h. This charging method has no special requirements for the power grid. It can be used as long as the power supply quality can meet the lighting requirements.
Small charging station is one of the most important charging methods for electric vehicles. Charging piles are set in the streets, supermarkets, office buildings, parking lots, etc. The driver of the electric vehicle only needs to park the vehicle at the designated position of the charging station and connect the wire to start charging. The charging method is generally card swiping. The charging power is generally 5 ~ 10kW. The typical charging time is: 1 ~ 2H of charging and 5 ~ 8h of full charge.
DC electric vehicle charging station, commonly known as "fast charging", is a power supply device which is fixed outside the electric vehicle and connected to the AC power grid, and can provide DC power for the power battery of off board electric vehicles. The input voltage of the DC charging pile adopts three-phase four wire AC380V ± 15%, the frequency is 50Hz, and the output is adjustable DC, which directly charges the power battery of the electric vehicle. As the DC charging pile adopts three-phase four wire system for power supply, it can provide sufficient power, and the output voltage and current can be adjusted in a wide range, which can meet the requirements of fast charging
In recent years, the principle of the foreign research results is like that of the mobile phone used in the car -- converting electric energy into a special laser or microwave beam that meets the requirements of the current technical standards, and installing a special antenna on the top of the car to receive it. With wireless charging technology, electric vehicles or dual energy vehicles running on the road can quickly supplement electric energy through transmitters installed on electric poles or other high-rise buildings. The electricity charge will be deducted from the prepaid card installed on the vehicle.
Sored DC portable mobile charger consists of intelligent and efficient module, main control unit, human-computer interaction interface, charging interface, metering and billing unit, communication interface and other parts to form a small portable and multi-functional DC charger; The friendly man-machine interface facilitates the operation and use of users, and the modular design facilitates the expansion and maintenance of equipment; Support fully automatic charging mode;
Portable mobile DC charger has strong anti-seismic ability and complete protection functions, and is suitable for harsh outdoor mobile environment and emergency needs; It is a convenient place for customers to quickly respond to emergencies and test and supplement electric energy, and effectively make up for the problem of charging failure caused by compatibility with various charging pile software.
