Our work departs from the NASA randomised usage dataset , which randomly cycles cells for 50 cycles before measuring the next cycle discharging capacity after charging via a 'reference' protocol. Although several models for forecasting degradation under randomised conditions have been built based on this data , the effect of a single protocol on next cycle discharge capacity cannot be disentangled, and there is a need for a reference charge / discharge protocol every few cycles which is not realistic for the EV setting.
