Introduction

Pluggable energy storage technologies have a number of needs and prospects in certain areas. Energy storage list for electric vehicles and renewable energy

The emergence of meta and other applications requires specification to ensure safe and reliable operation, interchangeability, environmental protection and energy efficiency. Industry needs

It is expected to promote technological development and popularize pluggable energy storage technologies.

There are some special points to consider compared to other accessory products. The docking process may not be able to find the connector by human manipulation.

The correct position of the two parts. The docking process may have mechanical feed that will prevent the correct position of the two parts of the connector from being found. To overcome these questions

The accessory design can include partially movable parts to compensate for mechanical feed and tolerances.

Low voltage docking connector for mobile energy storage unit

1 Scope

This standard specifies the technical requirements for the structure, mechanical properties, electrical performance and other requirements of low-voltage docking connectors for mobile energy storage units.

This standard applies to low-voltage docking connectors (hereinafter referred to as accessories) installed or fixed on electrical equipment. This attachment is expected to be used

The mobile energy storage unit is coupled to a dedicated power conversion unit, energy consuming unit, or another energy storage unit.

These accessories are intended for direct current and may include ground contacts and/or optional signal and data auxiliary contacts. Rated current of these accessories

Not more than 800A, the rated working voltage does not exceed 1000Vd.c.

These accessories are not intended for plugging and unloading under load. These accessories are expected to be exclusively used by professionals (GB/T 2900.73-

2008, definition 195-04-02) or technician (GB/T 2900.73-2008, definition 195-04-01) installation.

The preferred ratings listed do not exclude other ratings.

This standard applies to accessories used in the environment specified in Chapter 32.

These accessories are intended to be connected only to copper or copper alloy cables with or without plating.
