Top 3 Reasons Why Battery Pack Development Gets Delayed

Written by Anton Beck
Posted on September 20, 2018 at 2:37 PM

When developing a custom battery pack, the last thing anyone wants is to hear their development hit a snag. Batteries already have a lengthy timeline going from concept to production, so staying on schedule is incredibly important. Of course, sometimes delays can just happen for reasons you have no control over, making it even more necessary to nail down the areas you can influence. Factors such as knowledge of certification requirements, manufacturing support capabilities, and prototyping processes can help keep your development on the right track.

What Makes a Smart Battery Pack...Smart?

Written by Anton Beck
Posted on September 11, 2018 at 10:21 AM

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).

Finding New Battery Suppliers Without Losing Your Battery Design

Written by Ed McMahon
Posted on December 29, 2017 at 9:49 AM

Over the past several years there have been several instances where battery suppliers that manufacture the highest technology batteries have run into financial difficulties (think A123, Boston Power) or change their business model and no longer want to supply small/medium volume applications (Panasonic). This has created several problems for OEMs as they have designed these cells and have passed all of the certification testing for UL, EMI, CE and UN DOT 38.3.

Custom Battery Pack Potting Process

Written by Anton Beck
Posted on December 14, 2017 at 3:27 PM

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.

PCB Conformal Coating With Battery Packs

Written by Mark Gaugenmaier
Posted on November 20, 2017 at 3:03 PM

It is important to be aware that certain applications will have battery packs that may be exposed to corrosive elements such as acidic, salt, and on occasion conductive substances and fluids. Over time this type of exposure can slowly corrode the PCBA, components, and solder joints. This type of corrosion can cause premature failure, short circuits, and or dangerous conditions that could lead to fire or even an explosion.
