Battery safety standards refer to regulations and specifications established to ensure the safe design, manufacturing, and use of batteries.
Series and parallel connections are the fundamental configurations of battery systems that enable large-scale battery energy storage systems (BESSs) with any type of topology. Series connections increase the system voltage, while parallel connections increase the capacity.
IEC 60086: International standard for the performance and safety requirements of primitive batteries. CE certification: Battery products that meet European battery standards need to obtain CE certification. REACH regulation: Chemical information is required to ensure the safety of battery materials.
When it comes to battery performance and safety, there aren’t any obligatory regulatory mandates; the primary reference points are the European Union’s battery performance and safety standards.
In practice this means that cells should not be wired in parallel unless they have proportionally matched capacities and resistances, otherwise the 'stronger' cell will discharge more than the 'weaker' one and the expected battery capacity will not be realized.
However, for most of today’s stationary batteries it is better to make parallel connections at the string level. One suggestion is to limit the number of strings in accordance with the system voltage, allowing more parallel strings at lower voltages.
The inconsistency of the self‐discharge rate of each cell in series has an impact on the capacity of the battery pack, which is one of the best interpretations of the Cannikin Law.
