A battery capacity translator () includes an input (), an output (), and a conversion circuit () coupled between the input and the output. The conversion circuit receives stored energy capacity information () corresponding to one or more energy storage cells of a first type at the input, and converts the stored energy capacity information to modeled stored energy capacity information () corresponding to one or more other energy storage cells of a second type. This modeled stored energy capacity information is delivered to the output to emulate the energy storage cells of the second type in legacy systems.

Battery capacity translator and corresponding systems and methods

A battery system includes a battery, a monitoring circuit, a wireless communication device and a remote wireless communication unit, and a deployable drone parachute. The monitoring circuit includes a processing unit and non-volatile memory that stores a unique identification of the battery. The wireless communication device is disposed on the battery and is in data communication with sensor circuits. The wireless communication device transmits real time operational parameter data sensed by the sensor circuits. The remote wireless communication unit is in wireless data communication with the wireless communication device and receives the operational parameter data therefrom.
