FOREWORD  
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisin g 
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote 
international co -operation on all questions concerning standardization in the electrical and electronic fields. To 
this end and in addition to other activ ities, IEC publishes International Standards, Technical Specifications, 
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC 
Publication(s) "). Their preparation is entrusted to technical committees; any IEC N ational Committee interested 
in the subject dealt with may participate in this preparatory work. International, governmental and non -
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely 
with the In ternational Organization for Standardization (ISO) in accordance with conditions determined by 
agreement between the two organizations.  
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international 
conse nsus of opinion on the relevant subjects since each technical committee has representation from all 
interested IEC National Committees.  
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National 
Committees i n that sense. While all reasonable efforts are made to ensure that the technical content of IEC 
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any 
misinterpretation by any end user.  
4) In order to promote  international uniformity, IEC National Committees undertake to apply IEC Publications 
transparently to the maximum extent possible in their national and regional publications. Any divergence 
between any IEC Publication and the corresponding national or re gional publication shall be clearly indicated in 
the latter.  
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity 
assessment services and, in some areas, access to IEC marks of conformity. IEC is  not responsible for any 
services carried out by independent certification bodies.  
6) All users should ensure that they have the latest edition of this publication.  
7) No liability shall attach to IEC or its directors, employees, servants or agents includi ng individual experts and 
members of its technical committees and IEC National Committees for any personal injury, property damage or 
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and 
expenses arisin g out of the publication, use of, or reliance upon, this IEC Publication or any other IEC 
Publications.  
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is 
indispensable for the correct applica tion of this publication.  
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of 
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

5 General safety considerations  
5.1 General  
The saf ety of lithium secondary batteries requires the consideration of two sets of applied 
conditions:  
1) intended use;  
2) reasonably foreseeable misuse.  
Batteries shall be so designed and constructed that they are safe under conditions of both 
intended use and reason ably foreseeable misuse.  
It is expected that batteries subjected to misuse can fail to function. However, even if such a 
situation occurs, they shall not present any significant hazards.  
Potential hazards which are the subject of this document are: 
a) fire,  
b) explosion . 
Conformity with 5.1 to 5.7 is checked by the tests of Clauses 6 and 7, and in accordance with 
the appropriate standard.  
5.2 Insulation and wiring  
Wiring and its insulation shall be suffic ient to withstand the maximum anticipated voltage, 
current, and temperature requirements. The design of wiring shall be such that adequate 
clearances and creepage distances are maintained between conductors. The mechanical 
integrity of the battery and its connections shall be sufficient to accommodate conditions of 
reasonably foreseeable misuse.  
5.3 Venting  
The casing of the battery shall incorporate a pressure relief function that will preclude rupture 
or explosion. If encapsulation is used to support cells wi thin an outer case, the type of 
encapsulant and the method of encapsulation shall neither cause the battery to overheat 
during normal operation nor inhibit pressure relief.  
5.4 Temperature/voltage/current  
The design of batteries shall be such that abnormal tem perature -rise conditions are prevented. 
The battery shall be designed within voltage, current, and temperature limitations specified by 
the cell manufacturer.  The b attery shall be provided with specifications and charge 
instructions for vehicle  manufacture r or battery -charger manufacturer so that associated 
chargers  are designed to maintain charg ing within the voltage, current and temperature limits 
specified.   
NOTE  Where necessary, means can be provided to limit current or voltage to safe levels during cha rging and 
discharging.  SASO STANDARD                                                    SASO DS IEC 63057:2023   
 – 12 – 
5.5 Terminal contacts of the battery  
Terminals shall have clear polarity marking(s) on the external surface of the battery , and the 
polarity marking(s) should be located near the terminal in order to be underst ood easily.  
The size and sh ape of the terminal contacts shall ensure that they can carry the maximum 
anticipated current. External terminal contact surfaces shall be formed from conductive 
materials with good mechanical strength and corrosion resistance. Terminal contacts shall be 
arranged so as to minimize the risk of short -circuits  (caused by metal tools, for example) . 
5.6 Assembly of battery  
5.6.1  General   
 The battery should  have an independent control and protection method.   
 The cell manufacturer shall provide recommendations about current , voltage and 
temperature limits so that the battery manufacturer  or designer can ensure proper design 
and assembly.  
 Protective circuit components should be added as appropriate , and consideration given to 
the vehicle .  
5.6.2  Battery  design  
The voltage contro l function of the battery  design shall ensure that the voltage of each cell or 
cell block shall not exceed the upper limit of the charging voltage specified by the  cell 
manufacturer, except in the case where the  vehicle  system  provide s an equivalent voltage 
control function.   
The following should be considered at battery level and by the battery manufacturer : 
For a battery  that has several series -connected cells or modules , it is recommended that the 
voltage s of any one of the single cells or cell blocks do no t exceed the upper limit of the 
charging voltage, specified by the cell manufacturer, by monitoring the voltage of every single 
cell or cell block.  
5.7 Requirements for the BMS  
The BMS evaluates the condition of cells and batteries, and it maintains cells and batteries 
within the specified cell operating region. Key factors of the cell operating region are voltage, 
temperature and current  for charging and discharging . 
The function s of the BMS can be incorporated in to the battery or into the vehicle  that uses th e 
battery.  The BMS can also be divided so that  it can be found partially in the battery and 
partially in the vehicle  that uses the battery ( see Figure 1). SASO STANDARD                                                           SASO  DS IEC 63057:2023

a) All function s of BM S are in the battery  b) BMS functions are divided  between   
battery and vehicle side  
Figure 1 – Examples of BMS locations and battery configurations  
A hazard analysis and risk assessment in accordance with Clause 8 of IEC 62619 :2017  shall 
be conducted on the battery and BMS combi nation . 
5.8 Operating region of lithium cells and battery for safe use  
Cells shall comply with the cell criteria outlined in IEC 62619 :2017 . The c ell manufacturer 
shall specify the cell 's operating region. The b attery manufacturer  shall design the battery to 
comply with the cell 's operating region . Determination  of the cell 's operating region is 
explained in  Annex  A of IEC 62619 :2017 . 
5.9 Quality plan  
The battery manufacturer shall prepare and implement a quality plan that defines procedures 
for the inspection of m aterials, com ponents, cells, modules, and batter ies and which covers 
the whole process of producing each type of cell, module, and battery (e.g. ISO 9001). The 
battery manufacturer  should understand their process capabilities and should institute the 
neces sary process controls as they relate to product safety.   
6 Type test conditions  
6.1 General  
A battery that is used outside of its operating region can exhibit hazards resulting from th at 
batter y. Such risks have to be taken into consideration in order to prepar e a safe test plan.  
The test facility  should have a sufficient structural integrity and a fire suppression system to 
sustain the conditions of overpressure , fire and electrolyte leakage  that can occur as a result 
of testing.  The facility should have a vent ilation system to remove and capture gas that might 
be produced during the tests. Consideration should be given to high -voltage hazards when 
applicable.  
Warning : THESE  TESTS  USE  PROCEDURES  THAT  MAY  RESULT  IN HARM  IF ADEQUATE  PRECAUTIONS  
ARE  NOT  TAKEN.  TEST S SHOULD  ONLY  BE PERFORMED  BY QUALIFIED  AND  EXPERIENCED  
TECHNICIANS  USING  ADEQUATE  PROTECTION.  TO PREVENT  BURNS,  CAUTION  SHOULD  BE 
TAKEN  FOR  THOSE  BATTERIES  WHOSE  CASINGS  MAY  EXCEED  75 °C AS A RESULT  OF 
TESTING . SASO STANDARD                                                    SASO DS IEC 63057:2023
