Method and device for controlling DCDC converter

An system for controlling a DCDC converter, wherein the system is applied to a hybrid-power vehicle, and the system comprises:

• one or more processors and a storage apparatus;
• and
• the storage apparatus stores a computer program which, when executed by the processor, perform the operations comprising:
• acquiring a first preset value corresponding to an input-terminal power according to a current limit value and an actual voltage value of an output-terminal;
• acquiring a second preset value corresponding to the input-terminal power according to a maximum discharging power of a high-voltage battery and an actual discharging power of an electric motor;
• and
• determining a minimum value of the first preset value and the second preset value to be an input-terminal target-power limit value.

A calculating and processing device, wherein the calculating and processing device comprises:

• a memory storing a computer-readable code;
• and
• one or more processors, wherein when the computer-readable code is executed by the one or more processors, the calculating and processing device implements a method for controlling a DCDC converter, wherein the method is applied to a hybrid-power vehicle, and the method comprises:
• by one or more processors, acquiring a first preset value corresponding to an input-terminal power according to a current limit value and an actual voltage value of an output terminal;
• by one or more processors, acquiring a second preset value corresponding to the input-terminal power according to a maximum discharging power of a high-voltage battery and an actual discharging power of an electric motor;
• and
• by one or more processors, determining a minimum value of the first preset value and the second preset value to be an input-terminal target-power limit value.
