The duration of a single battery swap for other commercial pure electric vehicles at highway service areas should not exceed 5 minutes. NOTE: the duration of a single battery swap refers to the time from when the vehicle is in place to when the battery swap is completed.

5.1.2 The number of battery storage spaces configured for the initial construction of a battery swap station shall be no less than 3, and it is advisable to have the function of expanding the battery storage spaces.

5.1.3 The battery swap station shall have the function of identifying and screening the battery status. The swapped battery shall be fault-free, and the state of charge (SOC) of the power battery shall generally not be less than 80% of the full charge.

5.1.4 The battery swap system equipped at the battery swap station shall have manual operation and one-button emergency stop functions. swap efficiency, transportation demands and operating routes. In addition, it shall be able to carry out network scheduling of the commercial battery swap vehicles and power batteries.

5.2.4 In addition to satisfying the relevant requirements of 5.2.1 ~ 5.2.3, the battery swap stations within the port shall also meet the following requirements:

a) The battery swap stations can withstand an operational wind resistance level of 8 and a main body wind resistance level of 12;

b) The battery swap stations use a solid foundation and anchoring system;

c) The battery swap stations use corrosion-resistant metal materials or perform special surface treatment on metal components;

d) The waterproof level of key components of the battery swap stations meets the IP54 requirement in GB/T 4208-2017;

e) The main structures and components of the battery swap stations are made of moisture-proof materials and sealing technology, and the equipment and components can normally operate in a high humidity environment;

f) The battery swap stations are equipped with a reasonable water drainage system. Drainage ditches, rainwater collectors, drainage pumps and other devices are set up in accordance with the surrounding terrain and climatic conditions, and waterproof pads or waterproof grooves are set up under the equipment.

5.2.5 In addition to satisfying the relevant requirements of 5.2.1 ~ 5.2.3, the battery swap stations in mining areas and transportation stations shall also meet the following requirements:

a) The battery swap stations shall use materials, such as: metal or plastic with smooth surface that are not easy to absorb flying dust and easy to clean;

b) The air intake and ventilation system of the battery swap stations should be equipped with high-efficiency air filtration devices;

6.1 Before Battery Swapping

6.1.1 Before a vehicle enters a battery swap station, if the charge of the replaceable battery in the battery swap station is less than 80% of the full charge, the driver shall be informed.

6.1.2 After a vehicle enters a battery swap station, the vehicle information shall be verified and the battery swap operation can only be carried out after the vehicle passes the identity recognition.

6.1.3 After a vehicle enters the battery swap channel, it shall first be positioned and its positioning status checked. If the vehicle positioning fails, at least one obvious alarm signal shall be issued in the form of voice, text, etc.

6.1.4 After the vehicle is successfully positioned, the on-site staff and driver shall perform the battery swap operation in accordance with the following steps:

a) Clearly inform the passengers not to get on or off the vehicle during the battery swap process;

b) Treat the high voltage AC power converted by inverter;

c) The driver performs parking procedures in accordance with the vehicle design requirements;

d) Exchange information between the vehicle and the battery swap station, and send information, such as: high voltage AC power converted by inverter and vehicle parking to the battery swap station;

e) Start the battery swap operation.

6.2 During Battery Swapping

6.2.1 The battery swap station should avoid abnormal movement of the vehicles that may affect battery swapping.

6.2.2 The battery swap station shall provide the driver with real-time status information of battery swapping through at least one mode, such as: screen display, voice prompt, client-end and vehicle-end.

6.2.3 When the system identifies that a person has entered the dangerous area determined by the battery swap station, the battery swapping shall be automatically stopped.

6.2.4 The battery swap equipment shall smoothly operate, and the battery swap system shall not be collided, deformed or damaged.

6.2.5 The electrical interface for battery swap shall not be energized, and the voltage between the positive and negative poles shall not be greater than 36 V.

6.2.6 The cooling interface for battery swap shall be automatically closed when separated, and the coolant leakage shall not exceed

0.5 mL when separated.
