scope:

This CP gives a description of the procedures and requirements related to documentation, design and type testing applicable for type approval (TA) of electrical energy storage (EES) systems.

The extent of type approval of an EES system should normally encompass:

- one or several defined combinations of cells in a module

- one or several defined combinations of modules in a string

- one or multiple strings in an EES system

- one set of main contactors or main circuit breaker (including control) for connection of the EES system to the charger/load.

This CP does not set the design requirements to the equipment. TA is based on compliance with design requirements given in the Society's rules and/or other regulations and standards. The CP describes the applicable design requirements and how to document compliance with the requirements in order to obtain a TA certificate for the equipment.
