When to Use a Floating Shield on Your Mil-Aero Cable Assembly

Written by Steven J Goodman
Posted on April 13, 2021 at 10:30 AM

Shielded cables are ubiquitous across nearly all industries. Not to be confused with armored shielding, which is designed to physically protect a cable, shielded cables are used to safeguard against electromagnetic energy and the negative consequences from signal corruption, blown components, or even a failed qualification test. Cable designers will specify whether a shield is required and its general construction. But just adding a shield to a cable may not be enough to achieve the required performance levels that are anticipated.

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.

Understanding Revision Control in Product Development

Written by Zak Gustavesen
Posted on March 25, 2021 at 9:45 AM

Revision control is the method by which manufacturers and engineers keep individual parts or assemblies documented and tracked. A more simplified definition could be that revision control is a part’s road map. In the world of manufacturing electronics, it is critical that revisions of any product are properly maintained and controlled.

Designing Accurate Fuel Gauges for Custom Battery Packs

Written by Anton Beck
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.

Advantages and Disadvantages of Embedded Battery Chargers

Written by Anton Beck
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.

Ohm's Law: What It Means for Flexible Heaters and Their Operations

Written by Chris Perry
Posted on February 23, 2021 at 9:31 AM

When talking about flexible heaters, determining the amount of efficient heat necessary for the application is required. A range of factors impacts generated electrical heat, including the materials that are used, the wattage, the voltage, the size of the heater, and the pattern of the conducive materials within the heater. One of the vital factors in designing a flexible heater revolves around Ohm's Law.

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.
