The invention discloses a driving power supply device and system, and relates to the technical field of power supply, the driving power supply device comprises a voltage conversion module, an on-off assembly and a trigger module; when the trigger module receives a trigger signal, the trigger module outputs a first opening signal to the on-off assembly, and the trigger signal comprises a high-voltage trigger signal; when the on-off assembly receives the first opening signal, a connection loop between the voltage conversion module and the high-voltage battery pack is conducted; the voltage conversion module converts a high-voltage trigger signal output by the high-voltage battery pack into a low-voltage driving signal and transmits the low-voltage driving signal to the driver. The high-voltage electricity output by the high-voltage battery pack triggers the on-off assembly to conduct the connection loop between the voltage conversion module and the high-voltage battery pack, the high-voltage electricity output by the high-voltage battery pack is converted into low-voltage electricity through the voltage conversion module to start the driver to work, and no extra low-voltage battery pack needs to be added to supply power to the driver. Cost is saved and space utilization rate is increased.
