In order to address the thermal management of the electric vehicle lithium-ion battery pack, intermittent pulsating flow is proposed to be applied to the multi-channel cold plate of the electric vehicle lithium-ion battery pack. Extensive numerical investigations on the maximum temperature (Tb,max) and maximum temperature difference (ΔTb,max) of the lithium-ion battery pack, transfer coefficient (h), pressure loss (Δp), efficiency index (EI), pump power (Ppump), and energy consumption (W) of the multi-channel cold plate under intermittent pulsating flow and pulsating flow are conducted. Results show that Tb,max and ΔTb,max under intermittent pulsating flow are lower than those under pulsating flow at the first half of the whole discharging process, which suggests that the intermittent pulsating flow can help the lithium-ion battery pack achieve better temperature characteristics. However, the W of the cold plate under intermittent pulsating flow is much higher than that under pulsating flow at the same pulsation amplitude and frequency. It is always increased at the fixed pulsation frequency with the increase in pulsation amplitude and reaches its minimum value at the pulsation frequency of 3 Hz when the pulsation amplitude is fixed.
