IEC 62619:2017 pdf download.Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries,for use in industrial applications
1 Scope
This document specifies requirements and tests for the safe operation of secondary lithium cells and batteries used in industrial applications including stationary applications.
When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this document, the former takes precedence (e.g., IEC 62660 series on road vehicles).
The following are some examples of applications that utilize cells and batteries under the scope of this document.
● Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy storage system, utility switching, emergency power, and similar applications.
● Motive applications: forklift truck, golf cart, auto guided vehicle (AGV), railway, and marine,excluding road vehicles.
Since this document 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 analysis of Clause 8. In regard to details for addressing electrical safety, the end use application standard requirements have to be considered.
This document 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. T he manufacturer clearly declares the tested unit. The manufacturer may add functions, which are present in the final battery to the tested unit.
5.2 Insulation and wiring
Wiring and its insulation shall be sufficient to withstand the maximum anticipated voltage,current, temperature, altitude and humidity requirements. The design of wiring shall be such that adequate clearances and creepage distances are maintained between conductors. The mechanical integrity of the whole battery system (cell/module/BMS) and their connections shall be sufficient to accommodate conditions of reasonably foreseeable misuse.
5.3 Venting
The casing of a cell, module, battery pack, and battery system shall incorporate a pressure relief function that will preclude rupture or explosion. If encapsulation is used to support cells within an outer case, the type of encapsulant and the method of encapsulation shall neither cause the battery system to overheat during normal operation nor inhibit pressure relief.
5.4 Temperature/voltage/current management
The design of batteries shall be such that abnormal temperature-rise conditions are prevented.Battery systems shall be designed within voltage, current, and temperature limits specified by the cell manufacturer. Battery systems shall be provided with specifications and charging instructions for equipment manufacturers so that associated chargers are designed to maintain charging within the voltage, current and temperature limits specified.
NOTE Where aplicable, means can be provided to limit current to safe levels during charge and discharge.IEC 62619 pdf download.
