ENVIRONMENTAL DESIGN CONSIDERATIONS
The performance of a battery, like most electronics, is greatly affected by temperature. All battery packs are designed to operate within a safe temperature range for the cell chemistry selected. For some chemistries, like Lithium-Ion, safe operation of the battery is critically dependent upon temperature. The range for safely charging Lithium chemistries is typically 0°C thru 45°C, which is narrower than the safe range for discharge, typically -20°C thru 60°C. Any heat generated during charge and discharge will be considered for every design, as well as external environmental temperature influences like sunlight. Thermal gradients in a battery can cause imbalances in cells and reduce cycle life, so proper consideration is critical. NBS can perform complete and accurate thermal analysis of battery performance in any environment. We will choose the right chemistry for your application.
Many other considerations can affect battery performance, including altitude, humidity, etc. Many of our designs meet the strictest military standards, such as MIL-STD-810. NBS has also done many designs to ATEX, with encapsulation, and for intrinsic safety. Our enclosures can also be designed to meet any IP Code. Several of our designs work very well in wet environments. We have the capabilities to design, from cell to electronics to mechanical enclosure, a battery pack that will work in any environment.
