CATL published a document in 2024 that looked at BESS lifecycle and durability [1]. BESS = Battery Energy Storage System and covers everything from Home, Commercial through to grid storage. In this instance CATL were looking at grid storage units. As they point out, the characteristics: when compared to automotive they see the challenges: This … Read more
Historically the inputs to an electricity grid have been large rotating machines that inherently have a large inertia. This means that even with a large change in demand in failure of a supply element the frequency is maintained. A small change in frequency is often an indicator that a change in supply is required. The … Read more
This is Rimac’s first move into the stationary energy storage market, their first product is the SineStack. The interesting aspects of this design is the integrated inverter, active balancing and the ability to switch the load on a module basis to extend the working lifetime. Specifications This post has been built based on the support … Read more
