Analysing the performance of liquid cooling designs in cylindrical lithium-ion batteries

•The performance of two liquid cooling designs for lithium-ion battery packs was investigated.•The effects of channel number, hole diameter, mass flow rate and inlet locations are investigated.•This study shows the maximum temperature difference of the CCHS is significantly less than the MCC.•Considering maximum temperature and temperature uniformity, the MCC design provides superior performance to the CCHS.
