GB/T 46713.5-2025 Active

This document specifies the general requirements, mechanical requirements, electrical interfaces, marking, transportation, and storage requirements for lithium-ion batteries used in auxiliary power supply systems for rail transit locomotives and rolling stock, and describes the corresponding test methods. This document applies to lithium-ion batteries (hereinafter referred to as "batteries") used in auxiliary power supply systems for locomotives and rolling stock. This document specifies the interface requirements between batteries, chargers, and battery management systems. Batteries are mainly used in auxiliary power supply systems, but they can also be used in other situations: — Temporary traction, such as shunting or rescue operations in depots; — Emergency mode (e.g., stopping in the third rail gap); — Reducing the peak power of the main power supply; — Reducing engine start-stop cycles. Note: If the nominal voltage of the battery exceeds the range specified in Table 1 of GB/T 46713.1–2025, the battery shall comply with GB/T 44386.
