The discharge capacity is directly proportional to the SOC of the battery. In Figure , the discharge capacity drop, or SOC drop, is relatively small for trips lasting around 800 seconds. To better quantify charge consumption, we introduce a new metriccharge usage score, which measures the SOC drop of each current profile relative to the reference current profile described earlier. Mathematically, the charge usage score is expressed as a percentage, as shown in Equation . A charge usage score below 100% indicates lower charge consumption compared to the reference profile, while a value above 100% suggests higher charge consumption, signaling the need for modifications in that particular trip by adjusting the route, driving behavior, or charging strategy.
