TECHNOLOGY COMPARISON

Not all battery packs are made equal. Relectrify battery and inverter control technology demonstrably outperform standard solutions. Find out the why and how in the sections below. 


 

THE PROBLEM

To efficiently provide substantial power output, large battery packs contain tens to hundreds of series-connected battery cells (or blocks of cells). The downside of this arrangement is that in series-connected cells, the pack capacity is limited by the capacity of the weakest cell. 

New high-quality battery cells have very low variability, but as they age their variability increases notably. Throughout a second-life operation, this variability stands to increase further, causing pack capacity performance to rapidly decline further throughout the operating life (whether in a new or second-life application) until one cell entirely fails to perform, at which time the whole pack is rendered useless. As such, the limitations due to cell variability drastically reduce the performance and lifetime of battery packs, and in particular for second-life. 


THE SOLUTION

Relectrify control technology combines power electronics with battery monitoring and optimisation algorithms to provide high-flexibility cell level control and battery inverter capability.

As a plug-and-play system, it also removes the need to sort and test used battery cells.

When placed inside new or second-life battery packs, Relectrify technology unlocks additional battery lifetime and safety. This enables our customers to build uniquely affordable, capable and sustainable storage products for residential, industrial and grid-scale applications.
