Predicting electrochemical energy storage device electrical load capacity involves deriving phase state in device from temperature difference, temperature-dependent specific heat, latent heat

摘要

The method involves direct or indirect measurement of the temperature of the energy storage device and of the ambient temperature, deriving the heat input to or output from the energy storage device from the difference between the temperatures and using this to derive the phase state in the device with the temperature-dependent specific heat and latent heat of the device.
