Tech talk: World first double whammy

Big congrats to our friends at Relectrify for achieving not one, but two world firsts! Certification of the BMS+Inverter technology marks a global first for a commercial and industrial scale storage product using cell-level control to be certified to the internationally recognised IEC standards. The product is also the first battery energy storage product using repurposed EV batteries to be certified for on-grid deployment in Australia. How exciting to be partnering with such go-getters!

The battery energy storage system passed several sets of standard tests to gain certification:

Performance: IEC 62477-2 and IEC 62477-1 are the standards for power electronic converter systems (PECS) and equipment; AS/NZ 4777.2 specifies the expected operation and behaviour of inverters on the Australia and New Zealand grid.

Safety: IEC 62619 is a safety requirement for secondary lithium cells and batteries for use in industrial applications and the IEC 60730 safety standard defines the test and diagnostic methods that ensure the safe operation of embedded control hardware and software. IEC 62109-1 applies to technical safety for power conversion equipment for use in photovoltaic systems. IEC 62109-2 covers the particular safety requirements relevant to DC to AC inverter products as well as products that have or perform inverter functions in addition to other functions.

Batteries: IEC 62040 is an international standard that applies to stationary batteries for use in certain applications and environments relevant to the Relectrify ReVolve®.

EMC: AS61000-6-3 ensures compliance with electromagnetic compatibility emissions standards.


Our take

Something for the team at Relectrify to be super excited about. As the proud parents of one of these cutting-edge battery energy storage systems, we know how much hard work has gone into achieving these significant milestones. We can't wait to see more of these BESS built with repurposed EV cells in the wild.
