NOTE: the electrical self-balancing vehicle is referred to as the self-balancing vehicle for short. 3.2 steering column A component used to control the steering of an electrical self-balancing vehicle, which may be equipped with other electronic displays or lighting equipment. 3.3 remote control software An application software installed on an intelligent mobile terminal to set up, control or monitor an electrical self-balancing vehicle via a wireless connection. 3.4 safety alarm An alarm (such as: sound, light and vibration, etc.) that may be clearly noticed by the user after being sent to the user, when an electrical self-balancing vehicle detects internal faults (such as: abnormal battery voltage and balance control unit failure) or dangerous driving actions or abnormal working conditions of the vehicle. 3.5 brake An action of an electrical self-balancing vehicle to stop or decelerate its wheels by self- induction. 3.6 rated mileage The mileage accumulated during the period when a fully charged electrical self-balancing vehicle runs at a constant speed of 60% of the maximum speed prescribed by the manufacturer on a flat hardened surface at a total load of 75 kg at room temperature, then travels at the maximum speed that it can reach in the case of failing to run at the speed above due to low power, until the self-balancing vehicle is unable to continue running due to low battery power. NOTE: rated mileage is in unit of kilometer (km). 4 Classification of Electrical Self-balancing Vehicles 4.1 In accordance with the number of wheels, it may be classified as: a) electrical one-wheeled self-balancing vehicle -- an electrical self-balancing vehicle with only one wheel, including two tires on one wheel; b) electrical two-wheeled self-balancing vehicle -- an electrical self-balancing vehicle with two wheels; c) electrical multi-wheeled self-balancing vehicle -- an electrical self-balancing vehicle with three or more wheels. 4.2 In accordance with the steering mode, it may be classified as: a) electrical self-balancing vehicle with a steering column; b) electrical self-balancing vehicle with no steering column. 4.3 In accordance with whether the seat is equipped, it may be classified as: a) electrical self-balancing vehicle with a seat; b) electrical self-balancing vehicle with no seat. 4.4 In accordance with the charging mode, it may be classified as: a) rechargeable electrical self-balancing vehicle with external power supply -- this type of electrical self-balancing vehicle is not directly connected to the AC grid during charging, but connected to AC grid via a charger or external power supply for charging; b) rechargeable electrical self-balancing vehicle with built-in power supply -- this type of electrical self-balancing vehicle is directly connected to the AC grid during charging. 5 Technical Requirements 5.1 Main Technical Performance Requirements 5.1.1 General The design of the main technical performance of the self-balancing vehicle shall firstly satisfy the requirements for safe driving.
