TECHNOLOGY COMPARISON

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


 

THE PROBLEM

Large battery packs like those in electric cars contain many individual battery cells. Each battery cell has lower and upper thresholds that define the points to which the cell can safely be discharged and charged. Exceeding these thresholds reduces the life of the cells and may risk battery failure. Standard battery packs permanently series connect some or all battery cells. During operation, each cell is monitored and when a single cell reaches the threshold, the entire pack disconnects. Where battery cells are identical and electrically balanced, they will reach these thresholds at the same time. But when cells differ in capacity or state-of-charge, thresholds are not reached at the same time. In this case the single lowest performing cell becomes the weakest link and limits the performance of the entire pack. New battery cells are manufactured to be closely consistent to minimise this issue. However, throughout their lives the cells unavoidably diverge. This reduces the performance of battery packs and leads battery packs to be discarded prematurely. It also makes repurposing of batteries an expensive process and limits both the performance and lifetime of resulting second-life battery packs. 


THE SOLUTION

Relectrify's control technology is an affordable plug-and-play solution that delivers personalised health care to battery cells within large battery packs. It not only conducts advanced condition monitoring of individual cells, but further leverages unique optimisation algorithms to provide high-flexibility cell level control for the battery pack. 

The resulting solution enables second-life battery packs with reduced pre-processing needs, that offer an increased storage capacity and cycle life.

Relectrify's intelligent monitoring and control solutions have been externally tested and verified by the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
