Battery Charging – A Rapidly Changing Technology

Battery charging technology is crucial for energy storage purposes, particularly for renewable technologies being used in mobile and critical backup systems. One of the biggest areas of growth and research in modern charger technology is with the new battery chemistries and the optimized ways to charge them. In an increasingly energy conscious and mobile culture, adaptable and renewable energy sources are highly sought after, and the market is flooded with different types of technologies and chemical variants all competing based on their unique characteristics.

Lithium ion batteries have been popular in consumer electronics primarily due to their improved energy density and lifespan over other types of battery charging chemistries. PCTI has partnered with Voldin Energy, a leading supplier of custom battery solutions for large scale industrial applications. Recognizing the advantages of newer innovative battery charging chemistries, we decided to form a mutually beneficial partnership that allows each company to play on their strengths, Voldin to the design and manufacture of the leading-edge batteries to fit the applications, and PCTI to the design and manufacture the leading-edge units that charge them. Customization for battery systems and charger design allows for great flexibility, which permits us to address our customers application-specific objectives with the best solutions that precisely meet their needs.

In one project for the PCTI and Voldin partnership, lithium-ion batteries were implemented in an innovative battery charging system for electrical underground mining equipment. These low-profile vehicles move both material and people. Previously, with lead acid batteries, it would take 8 hours to charge and allow the batteries to cool before they could be reused  again requiring two to three separate battery systems for each machine. In addition the changing process took up to 30 minutes and required large areas filled with batteries and chargers. Now, with the PCTI and Voldin systems, it requires only 15 minutes to charge the battery while it remains on the vehicle. Additionally a single battery charger can support multiple vehicles. Lithium ion batteries also eliminate numerous environmental concerns as they are free of lead and 5 other substances banned in RoHS and have a life expectancy of over 5 times that of lead acid creating a lot less waste.

Voldin and PCTI’s partnership technologies are offering our customer a strong competitive advantage in the underground mining industry as well many other industries. Our technological advantages and flexibility encompass many different industries. We have products in both commercial and industrial critical backup systems, military applications such as submarine battery chargers, and more, on an international scale. Our expertise extends to and high-current charging applications from 25 to 2,000A and up to 1000V, and we offer a number of different control options, add-ons, and other features our customers may require. Check out our website for a more detailed list of general specifications. As battery technology progresses, PCTI will continue to provide great custom solutions for high current applications up to 3MW. It’s part of our commitment to give our customers great products to provide the latest solutions for both emerging technologies and classic applications. We’re excited to see what the future holds for renewable energy applications, and are proud of our role on the road ahead.
