Railway application – Environmental conditions for equipment.
It is therefore necessary to have a clear definition of the different profiles, as well as iiec their expected repetition over daily operation with possible insertion of emergency profile at some point. For Li-ion batteries this can be up to 12 months.
IEC 60623 Ed 4 English Version
Equipment on board rolling stock. Uec sizings shall be available for the operator on request. Reference source not found.
This part is not developed enough and should be discussed in the working group with participation of experts from the sector operators, OEMs, manufacturers. Railway application – Electromagnetic compatibility all partsespecially the IEC 6.
It incorporates adequate housing and a terminal arrangement and may have protective devices or circuits. Bookmark not defin Table 1b — Dimensions for vented nickel- cadmium prismatic cells in plastic containersError! ic
Environmental testing – Eic The aim is to control conformity of design and later of realization with the relevant specification. Therefore they cannot be applied on a specific profile basis. Bookmark not de Table 2 — Measurement tolerances in millimetres valid for widths and lengths Especially the annex 4.
Tests – Test B: Note 2 the nominal voltage of a battery of n series connected cells is equal to n times the nominal voltage of a single cell.
IEC System of Conformity Assessment Schemes
One has to differentiate the potential of an Li-ion railways batteries component when applying these standards. Although Li-ion batteries show a much lower risk of producing explosive gases, at the moment the complying with this regulation has to be discussed with the EBA, as there are no rail standards for this topic.
If acceptable by the customer it may be sufficient to do the worst case only. The details of the instrumentation used shall be provided in any report of results.
IEC Standard – Home
Therefore, they will not be mentioned in the following parts. The battery manufacturer has to specify the charging uec and intervals to be applied. Railway application – Insulation coordination. Tests – Test Ea and guidance: Preparation of instructions – Structuring, content and presentation Instructions and manuals are an important input for safety analysis, as the manufacturer has to describe here risks and how to deal with them during operation.

Exploring Batteries 606223 Bloom. This should accompany the batteries. Transportation 6. Some are only valid for low voltage e. Ventilation requirements on batteries Although this standard is not valid for Li Ion batteries, ventilation might be a topic for this type of batteries as well. Reliability testing; compliance test plans for success railways batteries ratio This standard can be important if a risk assessment is asking for a certain reliability for an Liion battery.
Railway Applications – Software for railway control and protection systems 6. Electronic equipment used on rail vehicles IEC It can be transported and replaced when the battery system is maintained. Nexeon Limited, a spin-off from Imperial College London, is. It is recommended that the number of tests is limited to those which are proven to be necessary. One has to differentiate between standards on a component level mainly valid for all three applications and standards on integration or function level.
Protective provisions relating to electrical hazards This regulation takes an important place considering an electrical storage supplying traction power in rolling stock.
The latter were included due to the risk of explosive gases H2 and O2 which can occur with lead acid batteries. Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for large format secondary lithium cells and batteries for use in industrial applications. Functional safety of electrical, electronic programmable electronic safety-related systems IEC At present there is no rail standard dealing with this topic, this could be an issue for future standardisation.
An example for that would be shock and vibration tests. The manufacturer shall state the expected SOC and ageing behaviour for a given specification and provide evidence of the expected battery behaviour.
Variations of those profiles for seasons could be considered if having a significant impact on the load profile.
