What to Expect for Battery Development Timelines

Written by Anton Beck
Posted on March 29, 2021 at 9:15 AM

Customers requiring batteries for their products or applications have become savvier when it comes to the developmental phase of the battery packs. They understand that by having researched power requirements, dimensions of the pack compartment, battery chemistries, and cabling specifications, the customer can develop more comprehensive design documents. Then, the battery pack manufacturer can use these specifications to get started on the development and tooling stage immediately.

Posted on March 16, 2021 at 9:45 AM

When designing a custom battery pack, a topic that will come up between the manufacturer and the customer deals with the fuel gauge. The battery fuel gauge can be found in a range of everyday devices that we use, such as cell phones and computers. The function of the fuel gauge is to inform the customer on how much state of charge (SoC) and state of health (SoH) is left in the battery. The fuel gauge can predict the remaining capacity by measuring the voltage, battery temperature, and current.

Posted on March 1, 2021 at 9:45 AM

When deciding on the types of power to supply equipment requiring high performance, rechargeable batteries are often chosen for several reasons. With rechargeable batteries, users can obtain longer device performance and consistent power. In addition, rechargeable batteries are ideal for devices that are lightweight, such as mobile applications. These devices may have a battery pack that can be taken from off the device, such as the ones on power tools, and placed into a charger that connects to a wall outlet.

Integrating GPIO Options in Your Custom Battery Pack

Written by Anton Beck
Posted on February 19, 2021 at 9:26 AM

Many applications do not run as standalone systems. Instead, there will be multiple subsystems involved that can perform a variety of functions for the work output or to monitor internal systems to ensure optimal and safe performance. These systems need additional logic support to keep systems running or to improve system performance. However, there will be times when the application itself does not have these logic functions originally installed. So, another system must be added into the application to provide these functions.

Common Failures in Lithium Battery Packs

Written by Anton Beck
Posted on January 5, 2021 at 9:45 AM

With electronics becoming more portable and lightweight, they require batteries that offer long hours of battery life before recharging. Lithium batteries are becoming common place in electronics such as smartphones, laptops, and tablets as they can last for up to 2 years to 5 years. However, failures can cause lithium battery packs to malfunction. The type of problem will be based on the construction of the battery pack, how it is charged, how it is used and handled, and environmental factors.
