BS EN 61427 is a European Standard series that discusses secondary cells and batteries for renewable energy storage. The main purpose of BS EN 61427 is to provide the various testing methods and general requirements of secondary cells and batteries for renewable energy storage
BS EN 61427-2 is the second part of the BS EN 61427 series applicable to secondary batteries used in on-grid Electrical Energy Storage (EES) applications and provides the associated methods of test for the verification of their endurance, properties, and electrical performance in such applications. The test methods are essentially battery chemistry neutral, i.e. applicable to all secondary battery types.
On-grid applications are characterized by the fact that batteries are connected, via power conversion devices, to a regional or nation- or continent-wide electricity grid and act as instantaneous energy sources and sink to stabilize the grid’s performance when randomly major amounts of electrical energy from renewable energy sources are fed into it.
Related power conversion and interface equipment are not covered by BS EN 61427-2.
BS EN 61427-2 on ‘grid connected renewable EES requirements and tests’ is useful for:
Energy generation from intermittent renewable energy sources is maximized by electrical energy storage systems. In times of high demand for electricity, excess stored energy can be used by the power distribution network.
BS EN 61427-2 provides you with details on general testing conditions such as the accuracy of the measuring equipment in terms of voltage, current, temperature, and time measurements. Test object battery selection and size considerations have also been discussed in BS EN 61427-2.
Tests for endurance in various aspects have been discussed such as:
Battery properties and electrical performance have been discussed in detail in BS EN 61427-2.
BS EN 61427-2 guidelines are a step towards promoting sustainability, and a more environmentally conscious lifestyle.
