Introduction

With the rapid development of my country's rail transit industry, battery products for auxiliary power supply systems are constantly being innovated and the technology is becoming increasingly mature. To adapt to...

To meet market demand, my country should maintain its international standards for battery technology in auxiliary power supply systems for rail transit and improve the auxiliary power supply system for rail transit.

The system battery standard framework, based on international standards and domestic application realities, is formulated using GB/T 46713 "Rail Transit Locomotives and Rolling Stock".

The standard GB/T 46713, "Auxiliary Power Supply System Storage Battery", is proposed to consist of five parts.

---Part 1: General Requirements. The aim is to standardize the electrical interfaces of battery systems by considering various types of batteries.

Based on specific load curves, the required capacity for various types of battery systems is calculated.

---Part 2: Nickel-Cadmium Batteries. The purpose is to specify the general requirements for nickel-cadmium batteries in auxiliary power supply systems of rail transit locomotives and rolling stock.

Requirements, mechanical requirements, electrical interfaces, markings, transportation, storage, and testing, while also specifying the use of individual/integrated nickel-cadmium batteries in rail transit.

Requirements for use on locomotives and rolling stock.

---Part 3: Lead-acid Batteries. The purpose is to specify the general requirements for lead-acid batteries in auxiliary power supply systems of rail transit locomotives and rolling stock.

Requirements, mechanical requirements, electrical interfaces, markings, transportation, storage, and testing, while also specifying the use of individual/integrated lead-acid batteries in rail transit.

Requirements for use on locomotives and rolling stock.

---Part 4: Nickel-Metal Hydrate Batteries. The purpose is to specify the general requirements for nickel-metal hydride batteries in auxiliary power supply systems of rail transit locomotives and rolling stock.

Requirements, mechanical requirements, electrical interfaces, markings, transportation, storage and testing.

---Part 5: Lithium-ion Batteries. The purpose is to specify the general requirements for lithium-ion batteries in auxiliary power supply systems of rail transit locomotives and rolling stock.

Requirements, mechanical design, electrical interfaces, marking, storage, transportation and testing.
