scope:

This Standard specifies requirements and tests for the safe operation of secondary lithium cells and batteries (hereafter referred to as cells and batteries, respectively) used in industrial applications including stationary applications.

When there exists a JIS or IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this Standard, the former takes precedence (e.g. IEC 62660 series on cells for the propulsion of electric road vehicles).

This Standard is applicable to the secondary lithium cells and batteries for stationary application and mobile application for industrial use. Practical examples for main applications are as follows.

a) Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy storage system, emergency power and similar applications.

b) Motive applications: fork-lift truck, golf cart, automated guided vehicle (AGV), railway, marine, etc., excluding road vehicles.

NOTE 1 Some secondary lithium cells and batteries are intended for portable devices. The safety of such secondary lithium cells and batteries are specified in JIS C 8712.

Since this Standard covers batteries for various industrial applications, it includes those requirements, which are common and minimum to the various applications.

Electrical safety is included only as a part of the risk assessment of Clause 8. In regard to details for risk assessment, the end use application standard requirements have to be considered.

This Standard applies to cells and batteries. If the battery is divided into smaller units, the smaller unit can be tested as the representative of the battery. The manufacturer clearly declares the tested unit. The manufacturer may add functions, which are present in the final battery, to the tested unit.

The requirements of performance and marking for secondary lithium cells and batteries for use in industrial applications are specified in JIS C 8715-1.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 62619:2017 Secondary cells and batteries containing alkaline or other non-acid electrolytes-Safety requirements for secondary lithium cells and batteries, for use in industrial applications (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.
