When it was first suggested that one of us do a piece for the newsletter on the impact of the current pandemic on anything battery related; I will be honest I did not see a lot of connection. That changed at 3:30 on a recent morning when I was awakened by a rather nasty thunderstorm. As I lay there, I wondered if our electrical service would survive, and had I remembered to put my phone and ...

Tcharge regulation can be relatively simple: When the I-'1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. Often, diversion control is the solution. Off-grid "hybrid" combinations of solar, wind, or microhydro have been around for decades. These renewable ...

Equipment installed in ships or offshore installations typically operate under tough conditions, and any possible equipment failures can have serious cost impact. Despite this, products not really suited for the applications are often chosen based on the initial cost rather than looking at the total cost of ownership. One example is the use of a modular marine AC UPS versus the use of a modified ...

Household energy storage batteries have been on the market for many years and left many varieties and sizes to choose from. Due to the rapid development of lithium technology, modern lithium battery systems quickly replace traditional lead-acid batteries, because manufacturers have developed intelligent and modular systems to adapt to different energy storage applications. A large number of ...

Thermal runaway in lithium-ion batteries is a critical concern for safety in electric vehicles. To mitigate the risk of thermal runaway in lithium-ion batteries, it is crucial to proactively implement comprehensive monitoring solution to provide early warning as preventive step against potential harm from lithium-ion battery thermal runaway incidents. As mandated by UN GTR 20 and GB 38031:2020, ...

In this paper, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV) and battery, is proposed. The sources are operated to deliver energy at optimum efficiency. An optimisation model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with ...

Energy efficiency companies waiting for federal stimulus money probably feel like they are being told, “The check is in the mail.” It is supposed to arrive, but when?The federal government will channel a large pot of the money through state agencies, so it is wise to keep an eye on announcements by governors and state energy offices. States must apply by May 12 for $3.1 billion in what is known ...

It’s that time of year again. Tomorrow is the Summer Solstice, aka the first day of summer, the longest day of the year, and the day of the year with more sunlight than any other in the Northern Hemisphere. For most of us in the U.S., we will experience somewhere around 15 hours or so of daylight tomorrow. But, did you know, more energy from the sun will reach the surface of the Earth in ...

The term “Sealed Maintenance-Free,” in my opinion, is a marketing-driven term. In the early 1980’s, when telephone Private Branch Exchanges (PBX’s) were being deployed into customer premises, computer mainframes were migrating out of dedicated computer rooms, and smaller computers were being situated in occupied office space. Consequently, users were demanding that the ...

How Lead-Acid Batteries Release Hydrogen Lead-acid batteries produce hydrogen and oxygen gas when they are being charged. These gasses are produced by the electrolysis of water from the aqueous solution of sulfuric acid. A Vented Lead-Acid (VLA) battery cell, sometimes referred to as a “flooded” or “wet” cell, is open to the atmosphere through a flame-arresting vent, and ...
