3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 19596, GB/T 29317-2021 and the following apply.
3.1
battery swap station
a facility that provides battery swap services for electric vehicles
Note: Also referred to as a battery swap station.
[Source: GB/T 29317-2021, 3.1.2.1]
3.2
safe handling area
a designated area capable of effectively managing thermal runaway batteries to prevent risks to personnel and equipment
3.3
bi-direction charger
a dedicated device that connects the swappable battery system to the power grid (or load) with a fixed connection, enabling bidirectional energy conversion and transmission
3.4
SBS charger
a dedicated charging device used for charging swappable battery systems within a battery swap station
[Source: GB/T 29317-2021, 8.1.6]
3.5
station-grid interaction
a process in which a battery swap station interacts with the power grid through communication, control, and energy management technologies to participate in peak shaving, valley filling, demand response, and frequency regulation based on the demand of the power grid, enabling bidirectional information exchange and energy transfer with the power grid
3.6
prefabricated battery swap system
a modular prefabricated battery swap equipment that allows for rapid on-site assembly
Note: A prefabricated battery swap system generally consists of SBS swap equipment, SBS storage equipment, SBS transfer equipment, charging equipment, monitoring room, power distribution facilities, and supporting load-bearing or protective structures.
3.7
prefabricated battery swap station
battery swap station primarily composed of prefabricated battery swap systems
4 General requirements
4.1 The design of battery swap stations shall consider factors such as the development level of battery swapping technology, application scenarios, planning, environmental conditions, land use, fire protection, and construction conditions. It shall meet the requirements of safety and reliability, economic feasibility, environmental sustainability, and ease of installation and maintenance.
4.2 The overall planning of the battery swap station area shall be coordinated based on the construction scale and the functional layout. The service capacity and construction scale of the battery swap station shall include a margin based on service demand forecasts.
4.3 A battery swap station shall include SBS swap equipment, SBS storage equipment, vehicle guiding system, supervisor and control system, driveways, and safety protection facilities. It may also include SBS transfer equipment, SBS chargers/bi-direction chargers, SBS inspection and maintenance equipment, power supply and distribution system, parking spaces, safe handling area, and other auxiliary facilities.
4.4 A battery swap station may have the capability to charge electric vehicles.
4.5 The general layout of a battery swap station shall follow the principles of rational process arrangement, clear functional zoning, convenient traffic flow, and efficient land use.
4.6 The design of a battery swap station should fully account for the safety of battery swapping, charging, storage, and transfer operations, while also incorporating supervising/control and emergency response capabilities.
4.7 The layout of a battery swap station shall facilitate the smooth entry and exit of electric vehicles and the operation of SBS swap equipment.
4.8 Effective measures shall be taken for the battery swap station to ensure the safety of operating personnel, drivers, on-site equipment, vehicles, and SBS.
4.9 A battery swap station should have station-grid interaction capabilities and be able to participate in peak shaving and demand response when the distribution grid has a high load rate and limited capacity for additional power acceptance.
