At Epec, we are in a unique position of having the capabilities to produce domestically at our Colorado tech center, our Massachusetts assembly facility, or your partner factories in Asia. This allows us both flexibility and control on prototype development, regulatory builds, pilot ruins, and production quantities.
In today's battery and charger market, most companies typically provide either battery pack assemblies or battery pack chargers, as opposed to providing both. In the past, buying a battery from one source and a charger from another worked just fine when using the older NiCd batteries with overnight chargers. However, due to new battery chemistries and the increasing need for faster charge times, careful matching of the charger to the battery has become essential. Without proper battery and charger matching, aspects such as safety, cycle life, and run-time may be greatly affected.
There are several factors to consider when selecting the type of battery cell to use in your battery pack design. Looking at the battery requirements and the dimensional space available are important. Another factor that comes up is pricing. The top tier manufacturer brands can be expensive, but there are also comparable solutions in Asia that will reduce the cost.
The shelf life of a rechargeable nickel metal hydride (NiMH) battery will vary depending on the storage temperature and the size of any attached load. The battery shelf life will also vary by manufacturer. Panasonic recommends the following for their NiMH battery cells.
Determining the cost of a battery pack with fuel gauge technology will vary depending on the accuracy of the battery fuel gauge required. The overall size of the battery pack will also have an effect on the final cost. For example, if a high-accuracy gauge is required on a small multi-cell battery, it could potentially double the cost. The good news is that the cost of battery cells become relatively small when factoring in the added value received from implementing a fuel gauge.
This is a brief overview of how our custom battery pack development process works here at Epec. The actual completion time of the development of a custom battery pack will vary depending on the requirements of the application itself. Understanding each of the necessary stages and length estimates of concept through production will help you become prepared leading up to development.
