Battery monitoring technology
High-precision battery life prediction technology
It is important for a device to know how long the remaining battery life is. Technology is required to predict the remaining life from the equipment usage history (e.g. the number of discharges) and the environmental temperature.

FDK's original technology
FDK has identified that the main cause of capacity deterioration in nickel-metal hydride batteries is deterioration (oxidation) of the hydrogen absorbing alloy, and we are able to simulate the deterioration of the hydrogen absorbing alloy based on the battery usage environment using CAE technology to achieve high accuracy. We have established a variety of battery life prediction technologies.
Relationship between cell degradation and alloy degradation
Battery monitoring system with highly accurate life prediction
We are developing a battery monitoring system that predicts remaining battery life and provides the user with replacement time guidelines while remotely monitoring the battery capacity and temperature using our original battery life estimation technology.
