Effect of Temperature and Discharge Rate on Electrochemical Performance of Fiber Nickel–Cadmium Cell

Health Factor Experimental Testing and SOH Estimation for Nickel Cadmium Batteries

“…The above studies have extracted health factors from the battery charging process, but some studies only considered a single health factor and are limited to the constant current charging process. There is little consideration given to the factors in the constant voltage charging stage, making it difficult to apply to the working conditions of direct 110V bus connection of nickel cadmium batteries in high-speed trains; Moreover, the working characteristics of nickel cadmium batteries are significantly different from those of lithium batteries [8,9]. The existing health factors and health estimation methods for lithium batteries are difficult to apply to nickel cadmium batteries, and they are also unable to cope with the health state estimation under high-speed train conditions.…”

Electrothermal Coupling Modeling and Electrothermal Dynamic Characteristics of Nickel-Cadmium Battery

“…The above studies mainly focused on lithium batteries, while there are significant differences in the operating characteristics of Ni-Cd batteries [17], [18], but few studies have been reported on the thermal model and thermal characteristics of Ni-Cd batteries. For this reason, this article identifies the Ni-Cd battery model parameters at different temperatures and SOC through HPPC experiments, analyses the heat production and heat dissipation characteristics of the discharging process, measures the parameters required for the thermal model, constructs a Ni-Cd battery electrothermal coupling model, which is used to predict the temperature change, and tests the model's correctness through experiments to provide the theoretical and data foundation for Ni-Cd batteries.…”
