Need help?Do you have a question about the GRASEN GSCS75067A-T08 and is the answer not in the manual?
This document describes the 40kW DC Charger, a product of Luoyang Grasen Power Technology Co., Ltd. and Luoyang Grasen New Energy Technology Co., Ltd.
The integrated DC charger is designed for electric vehicle charging. It supports single connector fast charging, fast feed, and simultaneous equal power charging with two connectors. The charger's operational zone includes an indicator light, a display screen, a card reader zone, and an emergency stop button. The indicator light shows power supply, charging connector, and fault status. The display screen provides charging information, while the card reader zone is used for identifying charging cards and displaying simple operation instructions. The emergency stop button is for cutting off power supply in emergencies to prevent accidents; it is not recommended for normal outages.
The charger operates within specific environmental conditions:
Key technical parameters include:
The maximum input current is 77A. Recommended cable specifications are YJV-316+210, with inlet terminals SC16-6×3+SC10-6×2. Copper cable in accordance with GB 50217 and GB/T 12706.1 is recommended.
The charger is suitable for lithium-ion power batteries, providing energy output greater than the rated power and maintaining high output voltage and current accuracy. The display is the primary man-machine interface for the charger, showing the state of charge, battery pack status, fault status, etc.
Installation: The 40kW charger is designed for ground installation, requiring a reliable and fastened foundation. The suggested installation size for embedded 4-M12 bolts is 475x230mm. Drainage measures should be in place to prevent immersion. A 2-meter clearance on the left and right sides is required for heat dissipation, and sufficient space in front for operation. The vertical inclination after fastening should be less than 5%, with a nut tightening torque of 28.5N·m. The operation site should avoid direct sunlight; an outdoor shade (rain-proof) shed should be added. Electrical installation must be performed by professional technicians. The AC input uses a three-phase five-wire system, and connections must follow inlet notes, ensuring the zero line and phase are not reversed to prevent unrecoverable faults.
Operation: Operators must receive DC charger operation training and hold relevant certificates. During operation, a uniform and insulation shoes must be worn, and long-haired staff should wear safety helmets. Before powering on, a thorough inspection is required to check for electrical damage, loose parts, and proper crimping of connection terminals. The front gate of the cabinet should be opened to switch the breaker to ON and test the air switch of the control circuit for short circuits. After the AC incoming line is powered on, the emergency stop button should be pressed, then the breaker and air switch tested with a multi-meter. Charging connectors, charging socket insulators, pin, and pin hole should be clean and free of foreign matter.
Charging System Introduction: The charger performs a self-check upon power-on. The main interface (Figure 2-4) displays 7 charging modes: automatic charging, time charging, energy charging, and SOC charging. The user can select different modes.
System Function Introduction: Clicking "system" on the main page leads to the system setting page (Figure 2-14), which includes password setting, position orientation, electricity bill setting, date setting, function setting, communication parameter, fault record, charging record, and screen luminance (9 functions). The electricity bill setting allows customers to set prices for tip, peak, flat, and cereal periods within 24 hours.
Charging Mode Introduction: The charger supports two-connector alternate charging, where each connector outputs at its rated power. If connector A is charging, after it finishes, the system automatically charges connector B.
Calibration Interface: The charger interface should be calibrated regularly (monthly or every two weeks for frequent users) to prevent screen shift and ensure a good operating experience. Calibration can be performed via a hidden interface accessible by clicking any screen interface or through the "System Interface" for after-sales personnel.
User daily maintenance ensures the charger remains in good condition.
Storage: Well-packed equipment should be stored in a well-ventilated area with temperatures between -35℃ and 55℃, and a monthly average relative humidity of less than 90%. Storage places must be free of corrosive and explosive gases and protected from rain, exposure, condensation, and frost. Storage period varies by environment:
The warranty covers products with defects caused by incorrect use, repaired within the warranty period from the date of purchase. It also covers issues arising from improper installation or use not in accordance with the operation manual, resulting in quality problems not covered by the warranty. The warranty does not cover:
Important Note: Non-professionals are not allowed to dismantle equipment assembly.
