In step S4032, when the working state of the target construction machine is the working state, the energy storage battery is charged by the engine of the target construction machine.
Therefore, the energy storage battery is synchronously charged in the normal operation process of the engineering machinery, so that the electric quantity of the subsequent energy storage battery is full when auxiliary power supply is carried out in the non-operation state of the engineering machinery.
Step S404, in response to the confirmation operation of the auxiliary power supply request by the user, the target engineering machinery is switched from engine power supply to energy storage battery power supply. Details refer to the description of step S304 shown in fig. 3, and will not be described herein.
In this embodiment, an auxiliary power supply method for an engineering machine is provided, which is applied to the charge and discharge control system 1022 shown in fig. 1, and is as follows: fig. 5 is another flowchart of an auxiliary power supply method of engineering machinery according to an embodiment of the present invention, as shown in fig. 5, the flowchart includes the following steps:

Step S504, in response to the confirmation operation of the auxiliary power supply request by the user, the target engineering machinery is switched from engine power supply to energy storage battery power supply.
Specifically, before the target construction machine is switched from the engine power supply to the energy storage battery power supply in the step S504, the method further includes:
in step S5041, the current electric quantity of the energy storage battery is detected in response to the confirmation operation of the auxiliary power supply request by the user.
Specifically, the current charge of the energy storage battery may be detected by detecting/reading the voltage of the energy storage battery.
Step S5042, determining the current power supply state of the energy storage battery based on the current power.
Specifically, the step S5042 includes:
and a step a1, judging whether the current electric quantity is smaller than a first preset electric quantity threshold value.
And a step a2 of determining that the current power supply state of the energy storage battery is an enabling state when the current electric quantity is not smaller than a first preset electric quantity threshold value.
When the voltage is higher than the preset voltage U3, it is determined that the auxiliary power supply system has discharging capability, the current power supply state of the energy storage battery can be set to be an enabling state, a prepared instruction is sent to the crane control system, and at the moment, the icon of the crane central control screen auxiliary power supply system is in a green (enabling state).
And a step a3 of determining that the current power supply state of the energy storage battery is a non-enabled state when the current electric quantity is smaller than a first preset electric quantity threshold value.
Specifically, when the voltage is lower than U3, the battery of the auxiliary power supply system is judged to be in a low battery state, and the battery low battery state is sent to the crane control system, the crane central control screen auxiliary power supply system icon is in a red (alarm state) state, and the crane central control screen auxiliary power supply system icon is in a non-enabling state and stops power supply.
In addition, in practical application, a multi-level electric quantity threshold value can be set, for example, the voltage of the energy storage battery is detected/read, when the voltage is between U3 and U2, U2 is larger than U3, the situation that the battery of the auxiliary power supply system is about to be insufficient at the moment is judged, the state that the electric quantity of the battery is about to be insufficient is sent to the crane control system, and the icon of the auxiliary power supply system of the crane central control screen is in an orange color (early warning state). When the voltage is larger than U2, the auxiliary power supply system is judged to have discharging capability, the current power supply state of the energy storage battery can be set to be an enabling state, a prepared instruction is sent to the crane control system, and at the moment, the icon of the crane central control screen auxiliary power supply system is in a green (enabling state).
And determining whether the energy storage battery can meet the power consumption requirement of the engineering machinery or not by comparing the real-time electric quantity of the energy storage battery with a set electric quantity threshold value, and determining whether the energy storage battery can carry out auxiliary power supply or not according to actual conditions.
Step S5043, based on the current power supply state, switches the power supply of the target construction machine from the engine to the power supply of the energy storage battery.
Specifically, the step S5043 includes:
and b1, when the current power supply state is an enabling state, switching the power supply of the target engineering machinery from the engine to the power supply of the energy storage battery.

In practical application, after a crane manipulator sees an auxiliary power supply request, whether to switch to an auxiliary power supply system is judged according to the field working condition. Because the system can be powered off after the engine is stopped, a certain time is needed for restarting the engine until the crane is in a working state, from the safety point of view, the system is not recommended to be directly switched to an auxiliary power supply system for supplying power from the engine power supply state, the engine and the energy storage battery can be powered together, the power supply capacity of the energy storage battery is gradually increased, and meanwhile, the running power of the engine is reduced until the engine is stopped.
And b2, when the current power supply state is a non-enabled state, suspending switching the power supply of the target engineering machinery from the engine to the energy storage battery, and carrying out auxiliary power supply alarm.
Specifically, the power supply alarm can be performed in a voice or light prompt mode and the like so as to promote a user to carefully switch the auxiliary power supply system, so that the normal power consumption requirement of the control room is not influenced.
