240kw Double Guns DC Charging Piles for Electric Vehicles

Smart, rugged, high-tech electric vehicle charging stations are available for any location: hotels, workplaces or multi-family residences. They can be configured with a global POS machine and support various global credit card payment channels such as UnionPay and VISA.

Function introduction

(1) Charging mode: During the charging process, the integrated charger dynamically adjusts the charging parameters and performs the corresponding actions according to the data provided by the ev battery management system, the self-check parameters of the charger and the instructions issued by the server, completes the charging process, and fills the automatic stop charging.

(2) Metering function: a smart electricity meter is installed inside the pile body to measure the output electric energy of the DC charger. The electricity meter is installed on the outlet side of the charger. It can also be adjusted to the incoming line side according to the owner's requirements.

(3) Charging function: It supports charging according to charging power, and supports configuration of parameters including rate time, charging unit electricity, charging rate and so on. The accounting management module reads the electricity data of the electricity meter in real time, and sets the electricity price of the electricity meter. Single unit can support self-built contactless IC card loaded with user information and amount information, and optional POS machine to support credit card payment.

(4) Human-computer interaction function: The man-machine interface adopts color LCD touch screen, the operation interface displays complete and rich information, convenient operation, friendly interface, equipped with card swiping, emergency stop button and other operation interfaces. At the same time, the man-machine interface can record and display the charging current, charging voltage, charging time, charging power and error information during the charging process; users can query personal information and pile information at the pile end, or set personal information such as password modification.

(5) Display function: mainly display power supply, charging, fault state indication, charging voltage, charging current, charged amount, highest and minimum voltage of vehicle battery, vehicle SOC, estimated remaining charging time, fault and alarm information; under the administrator authority, set pile IP address, coding, highest / minimum output voltage, maximum output current and other information, or query the factory setting information; clear and complete, which can be identified without ambient light source.

(6) Communication function: The PLC interface communicates with the ev battery management system to obtain the charging parameters and real-time charging data of the ev battery system. It has the function of communication with the superior monitoring system, supports GPRS wireless communication, Ethernet and other communication modes, and meets the relevant encryption requirements.

(7) Emergency stop function: with emergency stop function, can emergency stop charging through manual switch or superior monitoring communication command.

(8) Charging monitoring function: with the functions of leakage current monitoring, insulation monitoring and alarm, fault, sound and light alarm can be conducted through LED indicator. The charger monitors the status of the battery, and automatically adjusts the charging curve, charging current, single battery capacity and charging voltage according to the temperature and voltage of the battery.

(9) Protection and alarm function: when the DC output is overcurrent, the charger will automatically cut off the DC output and issue an alarm signal. When the DC output is short circuit, the charger automatically enters the current limiting output state; when the AC / DC conversion power unit is over warm, the charger automatically cuts off the DC output and sends an alarm signal. The charger has the function of lightning protection and surge protection, and has the function of preventing battery current backflow.

(10) Record storage function: monitoring has alarm record and event storage function, and can store historical charging consumption information.

(11) Emergency power off treatment: When the emergency stop button, control and guidance fault, communication fault of the charging management system occur, the charging machine can disconnect the DC output contactor within 200ms, and the output voltage drops to less than 60V within 1.5s.

(12) Over-temperature protection: the charger monitors the temperature of the charging gun and the temperature of the pile in real time. If the temperature occurs, the power is reduced until the charging is stopped.

(12) Remote upgrade function: the charger can remotely upgrade the program through the background management platform.

(13) Others: fully consider the security of the equipment: configure the access control switch, open the cabinet door for automatic alarm, to avoid live operation;
