Scope: This document specifies the general requirements for the user-side charging and replacement system of electric heavy-duty trucks, including overall vehicle requirements, component requirements, battery pack system requirements, emergency battery pack system requirements, and charging pile system requirements. This document applies to electric heavy-duty trucks and battery pack systems capable of charging and replacing batteries; Main technical contents: 1. The dimensions of a 25 kWh battery module should be 650 mm in length, 240 mm in height, and 630 mm in width. 2. The minimum unit of a normal-temperature battery module is 25 kWh, and the capacity of the battery pack system should be an integer multiple of the minimum unit, not less than 200 kWh. Recommended capacities are 200 kWh, 250 kWh, 300 kWh, and 350 kWh; the minimum unit of a low-temperature battery module is 20 kWh, and the capacity of the battery pack system should be an integer multiple of the minimum unit. 3. The standard voltage of the battery pack system should be greater than 600 V and less than 800 V, with recommended values of 600 V, 620 V, 650 V, 680 V, and 720 V. 4. The battery composition of the emergency battery pack system should be in the form of series, parallel, or series-parallel combinations; the operating temperature during charging should be between -20 °C and 55 °C, and during discharging, between -40 °C and 55 °C. 5. The charging pile consists of a pile body, an electrical module, and a metering module. The pile body includes a shell and a human-machine interface. The electrical module includes a charging socket, a cable terminal strip, and safety protection devices. 6. The environmental conditions of the charging pile should be -20 °C to 50 °C, with a relative humidity of 5% to 95%, an altitude of ≤2000 m, and an atmospheric pressure of 80 kPa to 110 kPa; the AC input voltage of the power supply should be within 380 V ± 15%, and the AC frequency should be within 50 Hz ± 5 Hz
