As electricity flows through charging cables and your EV’s internal circuits, it encounters resistance—a natural property of conductive materials. This resistance converts some energy into heat rather than storing it in the battery. The longer or lower quality the cable, the more heat is generated, leading to greater energy loss.
For instance, if you draw 10 kWh from the grid but only 9 kWh is stored in the battery, the charging loss is 10%. While it’s impossible to eliminate energy loss entirely during EV charging, there are several strategies you can employ to minimize these losses.
State of Charge In lithium-ion batteries, battery degradation due to SOC is the result of keeping the battery at a certain charge level for lengthy periods of time, either high or low. This causes the general health of battery to gradually deteriorate.
During charging and discharging process, battery temperature varies due to internal heat generation, calling for analysis of battery heat generation rate. The generated heat consists of Joule heat and reaction heat, and both are affected by various factors, including temperature, battery aging effect, state of charge (SOC), and operation current.
The lithium-ion battery heat generation was mentioned in previous research through thermal–electrochemical modeling [8 – 10], in which the internal heat generation during regular charge/discharge is presented as Eq. 1.
