Which is the best car charging pile manufacturer? How to choose a charging pile brand? Top 10 Charging Pile Brand Rankings Shenzhen evcome New Energy Co., Ltd. provides the Top 10 Charging Pile Brand Rankings to easily understand which charging pile brand is good and which charging pile products are good. New energy vehicles are the general direction of the development of the automobile industry. However, for new energy vehicles, the current problems are not performance, price, and brand issues, but mileage and charging issues. If the charging problem is not solved, the development of new energy vehicles will be difficult. are greatly restricted. At present, the total number of car charging pile manufacturers exceeds 300, and the entire industry is in a period of rapid development. Especially with the absolute capacity of 5 million planned in 2020, the overall development trend of the car charging pile industry is good. In recent years, the market is still in the early stage of development. Whether it is new construction or renovation, the participants are diverse, and there are still many uncertainties in the future car charging pile industry. Environmental parameters/requirements for the use of car charging piles: 1. Working environment temperature: -20°C~50°C for normal operation; 50°C~75°C derating output 2. Storage environment temperature: -40°C~75°C 3. Equipment installation location: No strong vibration and impact, no strong electromagnetic interference, the induction strength of the external magnetic field shall not exceed 0.5mT4, the installation vertical slope: not more than 5°Functional characteristics of car charging pile: 1. Connection confirmation function When it is detected that the charging gun head and the gun holder are correctly connected, the charger is allowed to start charging. 2. Communication function The charger has the function of communicating with the electric vehicle battery management system. After successfully shaking hands with the BMS, it can obtain the charging parameters and real-time charging data of the electric vehicle battery system, and dynamically adjust the output according to the real-time demand of the BMS. 3. Human-computer interaction function The human-machine interface adopts a color LCD touch screen, and the operation interface displays complete and rich information, which is easy to operate and has a friendly interface. 4. A variety of charging methods can choose fixed time charging, constant power charging, fixed amount charging and automatic full charging. 5. Status indication function Set status indication on the charging pile to indicate different working states. 6. Protection and alarm function Input overvoltage, undervoltage, short circuit, overtemperature protection, output overvoltage, overcurrent, short circuit protection, gun protection, insulation grounding protection, soft start time (3S~8S), battery reverse connection protection , abnormal connection protection, emergency stop protection, alarm and display. 7. Remote communication can communicate with background monitoring through Ethernet. 8. The design of the DC pile for the insulation grounding protection test complies with the requirements of GB/T 18487.1-2015, and the insulation resistance>500Ω/V consider safe; 100Ω/V<Insulation resistance≤500Ω/V for abnormal insulation alarm; insulation resistance≤100Ω/V is regarded as an insulation fault to stop charging. 9. The design of electrical protection DC piles complies with all requirements of GB/T 18487.1-2015 electrical protection, including general requirements mode, power supply equipment should have power supply circuit contactor adhesion monitoring and alarm functions, direct contact protection, and capacitor discharge. 10. Special requirements for vehicle interface and power supply interface The DC pile design complies with all the special requirements of GB/T 18487.1-2015 vehicle interface and power supply interface, including the newly added requirements for interface temperature monitoring and locking devices. 11. Emergency stop Press the emergency stop button and the charging pile will be powered off. 12. DC charging control guide circuit and control principle. The design of DC pile complies with GB/T 18487.1-2015. 13. The design of DC pile for DC charging vehicle interface locking device complies with GB/T 18487.1-2015. 14. Record storage function charger It has an alarm record storage function and can store historical charging consumption information.
