Lithium Ion Battery testing for vehicles
Introduction Lithium-ion batteries are used in many types of devices including over 60% of mobile phones and 90% of laptop computers. These batteries are inside iPods and iPads, as well as military and medical hardware. They are even powering pacemakers in the human body. However, the most significant growth in demand for Lithium-ion batteries is in the hybrid/electric vehicle market. This market ...

Battery Evaluation – Testing of Electric Vehicles
As electric vehicles continue to dominate the marketplace, several safety standard tests are being conducted to keep the vehicle working condition stable. These safety standard tests involve the evaluation of batteries for electric vehicles, with the distinct focus of testing performance, cycle life, and safety. Battery evaluation and testing elective vehicles are multifaceted and require to be ...

How the thermal runaway test chamber works?
As the valve-regulated battery uses a poor liquid design, the electrolyte poured into the battery is adsorbed on the fiberglass board. When the charging current increases, the gas needs to be released through the safety valve, which causes the battery to lose water and increase the internal resistance. The capacity decay and generate a lot of heat during charging and discharging. If the heat is ...

How to Do a Battery Load Test: Connecting a Constant Current DC Load Bank to a Battery System
Since the only way to truly determine battery performance is to conduct a load test, we have put together this simple 7-Step Guide to Connecting our SLB Series Constant Current DC Battery Load Tester to a Battery Bank: 1. Connect the load bank to AC power and turn the unit ‘on.’ Make sure breakers are in the ‘off’ position. 2. Connect the load cables from the load bank ...

Ways to Properly Charge Stationary Lead-Acid Batteries
After hundreds of site visits, multiple battery systems tests, and the examination of numerous maintenance records, I would say that almost 50 percent of all stationary lead-acid batteries are not being properly charged. Constant-Current Charging: Not generally used for stationary batteries except during the manufacturing process. Constant-Potential / Constant Voltage Charging: Used in ...

Microbiotests for the Evaluation of the Pollution from the Oil Shale Industry
Abstract : In this study a comparative chemical and toxicological analysis of 8 phenolic river water and wastewater samples originating from the Kohtla-Järve oil shale industry region (north-western part of Estonia) was made. The total phenolic content of the samples ranged from 0.01 to 195 mg/l. For 5 wastewaters the corresponding synthetic phenolic analogues were prepared. A battery of ...

Fiber Optic Testing Helps Ensure EV Battery Health and Safety
EVs face unique design challenges in order to be competitive with gasoline-powered vehicles. The root of many of these challenges is in the EV battery pack. Drivers want similar vehicle range per charge when compared to a tank of gas, as well as the convenience they are used to with refilling a tank in just a few minutes. This means battery packs need to be able to store enough energy to go ...

Monitoring Station at Lazina, Croatia
Geolux has recently installed an automatic hydrological monitoring station at a location in Croatia. The monitoring station is based on a compact Geolux HydroStation system. It consists of a radar level sensor LX-80, a surface velocity radar RSS-2-300W, a HydroCam camera, SmartObserver datalogger, a 20 W solar panel, and a 20 Ah lithium-ion backup battery. All instruments use contactless methods ...

Women Who Run with Tools
Last February, a group of dedicated and enthusiastic women descended on Tucson, Arizona to learn how to incorporate solar energy into their lives. Though it hasn’t always been this way, women wielding power tools and installing solar electric equipment is becoming more common. For the past three years, Solar Energy International (SEI), an educational non-profit based in Carbondale, Colorado, has ...

Why Do We Need Battery Monitoring If We Do Discharge Testing?
Introduction This is a question that is often asked, and the answer is relatively simple. A discharge test measures the capacity of the battery and a battery monitoring system is a maintenance tool. Let me explain further. The Importance of Capacity Testing A lead acid battery is a collection of lead-based electrochemical cells, each with a nominal voltage of 2 Volts, assembled in series to ...

Utilities and the Auto Industry: A Romance That’s Meant to Be
In 1882, Thomas Edison opened the first power plant, and 8 years later, William Morrison released the first electric car in the United States. The electric utility and auto industry were born and the two would dabble with the idea of working together. Henry Ford, a good friend of Thomas Edison, wanted to build an electric vehicle (EV) version of the Model T. He told the New York Times in 1914 ...

Con Edison to pilot $15M virtual power plant project
New York utility Consolidated Edison (Con Edison) plans to launch a pilot virtual power plant (VPP) project in June to test out the business case for integrating aggregated fleets of residential solar-plus-storage systems into the grid, Jamie Brennan, director of demonstration projects at Con Edison, told Energy Storage Update. The project will link hundreds of solar and battery storage systems ...

Next-Gen Battery Storage
A utility in Oregon recently announced the largest wind-solar-storage project in the U.S that will generate nearly 380 MW of energy. This is a good example of how utilities are storing energy from intermittent sources (like wind or solar) in grid-scale batteries. Grid-scale batteries are the perfect match to wind and solar installations, storing energy during peak production and releasing power ...

New approaches in battery monitoring architectures, design and methodologies
The typical dilemma of a backup battery system user is whether to rely on the guarantees of a battery supplier with regard to product performance, or to independently monitor battery status to ensure reliable backup power when the power is needed. This dilemma has created a vague sense of mistrust between battery suppliers and end users. More and more end-user decision makers, however, are ...

“Sealed Maintenance-Free” Batteries. What a Myth!
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 ...

Beyond the Tesla Powerwall: How energy storage is shaping up in Ontario - How energy storage changes everything
There are not many entrepreneurs who can command a room like Elon Musk. When he stepped onto a stage in May to unveil the Powerwall the audience oohed and ahhed and dutifully pre-ordered more than 38,000 of Tesla’s new home battery systems. And while Tesla gets the headlines other energy storage players shouldn’t be jealous. Musk just gave the nascent industry a billion dollars worth ...

Designing renewable contracts that value CSP storage
As California ramps up its storage requirements, it has not included Concentrated Solar Power (CSP) with integrated energy storage. Instead it is testing pilot projects using batteries at utility-scale, even though it must be obvious to bean counters at utilities that batteries are never going to compete with utility scale CSP storage. By Susan Kraemer The 32 MWh battery storage pilot for ...
