Cell design equipment during NOTES

October 22, 2013 - When it comes to the latest electronic device or gadget design, too often, the battery last thing to be considered, which leads to performance, security, and in some cases, expensive redesign, because the choice of battery is left only after the product.
UNIROSS Michael Rogers, MD, industrial lithium-ion battery manufacturer, meaning the points of discussion developed electronic device or gadget, depending on their source of battery power. He presented 10 points to consider before you start designing.
Ask the experts:
Although the Internet is a good source of information, but it can also be inaccurate and unreliable. Instead, a battery engineer or expert advice before starting any new progress.
Use a commonly available battery:
Always try to create your peripheral devices are commonly used battery size and chemistry. Because of economies of scale, large-scale production of batteries are cheaper and easier to obtain, and proceeded to design products, be sure to determine your size.
Tolerance:
While the battery is usually made in standard sizes, it is common to find the limit between different manufacturers, or parties. If possible, try to have your equipment to meet those tolerances for dimensions. It also allows you to switch on the line after the manufacturer's web site, if necessary.
Working temperature:
All batteries, whether chemical or manufacturer, it is easy - in extreme temperatures, the temperature is too high or too low. It is therefore very important that you consider the ambient temperature where you put the battery. At these temperatures may adversely affect the performance of battery.
Battery breath:
Where it is possible, as far as design for charging the battery in the battery compartment of breathing (sleep), expansion or contraction. The battery can be expanded and contracted during work or in the worst case, fanning herself with hazardous gases. The battery compartment that allows for this phenomenon is a good practice.
Avoid extra calories:
Battery is very sensitive to heat as possible to try to find the battery away from heat as much as possible to prevent the quality of services. Provision for ventilation or insulation can help.
The battery terminals:
Good quality with good battery terminals battery life is important. Pure nickel is the best material can be used in the manufacture of the battery contacts.
Low-voltage shut
Designed exception of equipment when the battery voltage falls below the device functional limitations. This is especially true on the device leaves a virtual open circuit voltage of the portable battery level drops. In these conditions, fluid leakage may occur.
Life:
Not everyone will achieve the same battery life. In addition, there are many factors that can affect battery life. Factors such as environmental conditions (high and low) and the operating conditions (discharge rate and depth of discharge, all of which help the service or the life cycle of the battery.
If you want to get 1000 bikes from the battery, for example, you have a battery, given the conditions. If you're not sure, but the life cycle of the battery of tests expert modeling. So you can be sure, in fact, the battery can make your life do you expect.
Transportation:
Most batteries are considered hazardous major airlines and their regulators, so they are limited to the commodity classification. This does not mean that you can not carry air batteries, but it is becoming increasingly difficult. This is especially true if you are developing a device containing a lithium battery type. At the beginning of the design process, using only the battery expert who can tell you a different battery chemistry transport rules and restrictions in order to avoid costly consultation after the fact.
