UL 2054: this is concerned with the safety of both commercial and household battery packs with regards to testing procedures.ANSI C18.1M: this refers to portable primary cells and batteries with an aqueous electrolyte.So, while those industry standards do not necessarily dictate which type of battery chemistry is to be used one way or the other, they do make an impact with regards to what happens after that selection has been made.Ī few of the other general battery industry standards include but are not limited to ones like: It provides an overview of elements like electrodes, the electrolyte, nominal voltage, and maximum open circuit voltage.Īll of this is important because it helps to make sure that batteries by various device manufacturers still work and perform in the exact same way, thus essentially making them interchangeable. When IEC 60086-1 is used as a battery classification tool, it also becomes a helpful way to standardize those electrochemical systems inside the pack. Last revised in 2015, it was intended to standardize those batteries with respect to essential factors like dimensions, terminal configurations, markings, test methods, typical performance, certain environmental aspects, and more.
One of those general battery standards is called IEC 60086-1, for example, and it governs primary batteries. This is called the battery's chemistry, and while there are certain industry standards that apply when working with such materials, the actual selection is usually based on the size of the battery and its eventual intended application. The Development of a Battery Pack: Chemistries, Enclosures, and More Battery ChemistriesĪt its core, a battery pack is made up of one or more electrochemical cells that are intended to store chemical energy to later be converted into electrical energy. When they do function exactly as intended, it is important to understand that this result is the product of an incredible amount of time, care, hard work, and technology that all went into its development.įrom battery chemistries to industry standards regarding enclosures to safety protections and beyond, here is everything you need to know about the proven technologies that suppliers rely on when developing custom battery packs (Figure 1) on a regular basis.įigure 1: SolidWorks 3D rendering of custom battery pack with cells, BMS, and plastic enclosure. Proven Technologies When Developing a Custom Battery PackĪ lot of us probably do not spend much time thinking about the battery packs that we interact with on a regular basis we are only concerned with whether or not they work.
