The study analysed the thermal effect on the energy imbalance of nickel-metal hydride (NiMH) batteries in hybrid systems; within this framework, the objective was to develop an experimental analysis of the thermal effect on the energy imbalance of NiMH batteries. Using an experimental approach, a battery module from a hybrid vehicle was evaluated through voltage and temperature measurements, as well as individual balancing tests. The results showed that the central cells reach higher temperatures, leading to greater degradation and energy imbalance. Furthermore, balancing and cell redistribution helped to standardise voltages and improve the health of the module. It was concluded that thermal management is crucial for optimising performance and extending the service life of the batteries.
