Abstract
A three-dimensional modelling approach is used to study the effects of operating and ambient conditions on the thermal behaviour of the spiral wound supercapacitor. The transient temperature distribution during cycling is obtained by using the finite element method with an implicit predictor-multicorrector algorithm. At the constant current of 2A, the results show that the maximum temperature appears in core area. After 5 cycles, the maximum temperature is 34.5°C, while in steady state, it’s up to 42.5°C. This paper further studies the relationship between the maximum temperature and charge-discharge current. The maximum temperature will be more than 60°C after 5 cycles at the current of 4A, and cooling measurements should be taken at that time. It can provide thoughts on inner temperature field distribution and structure design of the spiral wound supercapacitor in working process.
Highlights
Oil depletion, growing mobility demand, and increasingly stringent regulations on pollutant emissions and carbon footprint are expediting a paradigm shift towards a sustainable and efficient transportation [1,2,3,4,5]
We have studied the variation between the maximum temperature and cycle number after 50 cycles
Finite element analysis is adopted to analyze the distribution of inner temperature field of spiral wound supercapacitor in constant current charge-discharge experiment
Summary
Oil depletion, growing mobility demand, and increasingly stringent regulations on pollutant emissions and carbon footprint are expediting a paradigm shift towards a sustainable and efficient transportation [1,2,3,4,5]. Thermal Analysis on Spiral Wound Supercapacitor coefficient; qconv, is the heat flow rate per unit area of the convection heat transfer surface. Hamid Gallous [20] studied the thermal behavior of spiral wound supercapacitors at small-medium power, and used built-in thermocouple to measure inner temperature rise.
