Abstract (en)
[origin: WO2022038567A1] A control method of a locomotive dynamic device, a locomotive dynamic device and a locomotive are provided. The locomotive dynamic device includes a lithium-ion battery module and a hydrogen fuel cell module. The method includes: obtaining operating power value required for current operation of the locomotive; obtaining real-time charge value of the lithium-ion battery module; calculating output power value of the hydrogen fuel cell module according to the real-time charge value; obtaining output power value of the lithium-ion battery module according to the operating power value and the output power value of the hydrogen fuel cell module; controlling, according to the output power value of the hydrogen fuel cell module, the hydrogen fuel cell module to supply electric energy to a traction motor and the lithium-ion battery module, and controlling, according to the output power value of the lithium-ion battery module, the lithium-ion battery module to supply electric energy to the traction motor. The control method of the locomotive dynamic device can solve the problem of repeated charging and discharging of the lithium-ion battery module, and improve the overall energy utilization efficiency of the locomotive dynamic device.
