PNG Power with the support of IFC, a member of the World Bank Group, and donors Australia and New Zealand, has officially launched the first ever trial of rooftop solar power in Papua New Guinea. The move marks a significant change in policy. [pdf]
The project, owned and operated by AES Distributed Energy, consists of a 28 MW solar photovoltaic (PV) and a 100 MWh five-hour duration energy storage system. AES designed the unique DC-coupled solution, dubbed “the PV Peaker Plant,” to fully integrate PV and storage as a power plant. [pdf]
Finland has unveiled the world’s largest sand battery, a groundbreaking energy storage system designed to capture surplus power from renewable sources such as wind and solar. Standing 13 metres tall in the southern municipality of Pornainen, the facility can hold up to 100 megawatt-hours of energy. [pdf]
A battery management system (BMS) is any electronic system that manages a ( or ) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as and ), calculating secondary data, reporting that data, controlling its environment, authenticating or it.

[FAQS about Battery Management BMS]
A balanced battery pack is critical to getting the most capacity out of your pack, read along to learn how to top and bottom balance a lithium battery pack. .
Cell balancing is the act of making sure all cells in a battery are at the same voltage. When building a lithium-ion battery, the process involves connecting many cells together to form a singular power source. In ideal circumstances, brand-new cells will all be at the. .
Top balance is when the cell groups in a battery are balanced during the charging process. There are many applications that are well suited for top balancing, but the best example of such. .
There are several ways this can be achieved. Batteries can be top-balanced or bottom-balanced. They can be actively balanced or passively balanced. The quickest way to balance cells is by burning off the excess energy. For example, if all of your cell groups but. .
Bottom balancing, as you would expect, is pretty much the opposite of top balancing. Bottom balancing is used when getting the absolute most out of each discharge cycle is the most important. [pdf]
TAGENERGY, a global leader in low-carbon energy solutions, launches construction of France’s largest battery energy storage platform (France, Marne). This landmark project marks the start of an ambitious expansion plan for 2025, with accelerated solar and storage development activities. [pdf]
