Ground Charging System
To meet the fast-charging needs of new-energy locomotives, charging solutions are selected and configured in cooperation with leading charging equipment enterprises. The solutions adopt mature intelligent charging devices, which can meet the charging needs of various types of new-energy locomotives and feature low construction costs.
Qishuyan Company provides charging solutions that can be customized according to the user's new-energy locomotive application scenarios and on-site power configurations to meet the user's charging requirements.
Integrated Charging System
The charging gun and charging cabinet are integrated into a single unit, supporting 0.4KV low-voltage access, with a maximum charging power of up to 400kW and support for simultaneous high-power dual-gun charging.
For Chinese-standard new-energy locomotives with power levels of 500~2000KW, the minimum energy replenishment time for the locomotive power battery using the integrated charging system is shown in the table below:
| Locomotive Power Level | Battery Type Installed | Capacity Range | Charging Time |
| 500KW-2000KW | Lithium Titanate Battery | 300-1200kWh | 0.75h~3h |
| 500kW-2000KW | Lithium Iron Phosphate Battery | 600-2400kWh | 1.5h~6h |
[Features]
Full-scenario coverage: Core components adopt a full potting process with a maintenance-free design and strong environmental adaptability, suitable for applications in ports, mines, steel enterprises, and other scenarios.
High efficiency and energy saving: Low module standby power consumption, low system standby loss, and overall peak efficiency of up to 95%; core components are fully potted, resulting in a low failure rate and long effective service life; low noise and low radiation reduce interference with surrounding electrical equipment, making it environmentally friendly.
Safe and reliable: Active protection with active monitoring of the new-energy locomotive BMS operating status, battery characteristic parameters, and the charger's own operating status, enabling active diagnosis and handling of faults and abnormalities; the equipment is equipped with protection functions such as over/under voltage, overcurrent, and short circuit.
Rapid deployment: Short construction period and rapid commissioning.
