How a battery pack becomes qualified as “smart” is, quite simply, because of software. The Smart Battery System (SBS) forum defines a smart battery as a battery pack where some level of communication occurs between the battery, the equipment, and the user. As a further technicality, their definition also requires that a smart battery must provide state-of-charge indications (i.e. fuel gauge).
Although the progress of technology moves fast and batteries are more popular for supporting mobile devices, it should be noted that the actual battery chemistries haven’t changed much over the last several years. The shift in hand-held devices are for rechargeable solutions with more energy and lighter weight which targets lithium chemistry.
This blog post provides a quick overview of what is involved in the battery pack potting process. Battery potting can greatly aid in stability and help to optimize the performance of your finished custom battery pack. Potting materials are used to provide mechanical reinforcement to housed-assemblies and to protect components against exposure to harmful chemicals, moisture, mechanical shock and vibrations, and other hazards.
Some additional benefits of using battery potting include low cost shells, hermetic like seal, and good electrical insulation.
This topic is mainly focused on properly shipping lithium ion batteries due to shipping regulations, but could also apply to Ni-MH where appropriate.
When a lithium battery pack is designed using multiple cells in series, it is very important to design the electronic features to continually balance the cell voltages. This is not only for the performance of the battery pack, but also for optimal life cycles.
When designing and manufacturing battery packs, it is important to recognize that there will be limitations when dealing with specific cost and performance parameters. You may encounter circumstances where you will have to increase the cost of your battery pack or decrease aspects of the overall performance. We'll help detail some of those limitations and how to find solutions that help move your project forward.
We're very proud to report that our recent product webinar, Lithium Battery Regulations and How They Affect OEMs, had the most viewer responses ever for a webinar hosted here at Epec! Over 300 registered for the event, confirming that these latest changes to shipping lithium battery are of real concern amongst some of the industry’s leading Original Equipment Manufacturers (OEMs).
During our webinar "How Many Cycles Can I Expect from My Battery?" due to time constraints we were unable to get to all of the great questions submitted by our attendees during the Q&A session. One particularly important question stood out that we wanted to share and provide a detailed answer for on our blog.
At Epec, we are in a unique position of having the capabilities to produce domestically at our Colorado tech center, our Massachusetts assembly facility, or your partner factories in Asia. This allows us both flexibility and control on prototype development, regulatory builds, pilot ruins, and production quantities.
