CUSTOM NICKEL METAL HYDRIDE (NIMH) BATTERY PACKS
Custom Nickel Metal Hydride (NiMH) battery packs are an increasingly popular choice for many applications due to their low cost, durability, and low operating risks for the end user. This chemistry type can offer a wider operating temperature range than some lithium batteries, which, combined with the much lower development and product costs, makes NiMH the product of choice for many commercial and industrial applications.
Commonly used in applications that require low discharge rates, and where cost is a key factor, the nominal voltage rating of a Nickel Metal Hydride (NiMH) cell is 1.2V, with energy usable in the range of 1.0V – 1.45V per cell. A variety of cylindrical cell sizes are available, providing a capacity range from a few hundred mAh to above 10Ah, which gives designers of custom NiMH battery packs many different options when solving customer problems. NiMH battery packs can accept charge and discharge rates as high as 1C, and as a result, these custom battery packs are able to perform challenging tasks and require minimal time to recharge.
NiMH battery packs prefer a constant current charge where a standard charge can be C/10 for 14 hours. NiMH batteries can take a charge in as little as one hour with dT/dt (delta temperature/delta time) or peak voltage detect termination, along with several other metrics that can be monitors. It is always a good practice to incorporate a timer as backup in case the other methods fail to activate.
