The normally closed contact of the first relay K1 is connected to the chassis vehicle charging circuit 300, which is used to disconnect the connection circuit between the chassis vehicle charging circuit 300 and the backup battery 100 when the coil of the first relay K1 is energized.

[0031] Specifically, in this embodiment 3, the circuit structure of the chassis vehicle charging circuit 200 is the same as that of the chassis vehicle charging circuit 200 in the above embodiment 1, and will not be described again here.

[0032] Specifically, the working principle of the vehicle charging control system for a tool and equipment warehouse vehicle provided by this utility model is as follows: When an external power source (such as AC mains or generator power) is available, the external power charging circuit 200 is activated to charge the backup battery 100 and supply power to the temperature and humidity system of the tool warehouse vehicle. The specific process is as follows: First, the external power source (such as AC mains or generator power) is connected to the power converter U2 to supply AC220V power to the power converter U2. Then, the AC220V power is supplied to the charging inverter U3 through the power converter U2. Next, the AC220V stable voltage is supplied to the power output interface U4 through the charging inverter U3. Finally, the 220VAC stable voltage is supplied to the temperature and humidity system of the tool warehouse vehicle through the power output interface U4. At the same time, when the power converter U2 is powered, the backup battery 100 will automatically store energy (i.e., charge), the coil of the first relay K1 will be energized synchronously, the normally closed contact of the first relay K1 will be opened synchronously, and the chassis vehicle charging circuit 300 and the backup battery 100 will be disconnected synchronously.

[0033] When there is no external power source (such as mains power or generator power) and the chassis generator is not working, the backup battery 100 provides power to the charging inverter U3, which converts the 48V DC power output from the backup battery 100 into 220V AC power and outputs it to the power output interface U4. Finally, the power output interface U4 provides a stable 220VAC voltage to the temperature and humidity system of the tool warehouse vehicle.

[0034] When there is no external power source (such as mains power or generator power) and the chassis generator is working, the chassis vehicle charging circuit 300 charges the backup battery 100 and supplies power to the temperature and humidity system of the tool warehouse vehicle. The specific process is as follows: First, the chassis ON position signal is activated by the chassis key switch 302, which energizes the coil of the second relay K2. The normally open contact of the second relay K2 closes, connecting the chassis vehicle charging circuit 300 to the backup battery 100. After the chassis starts, the chassis DC generator G2 will provide 24VDC charging power to the vehicle charger. The voltage is then boosted to 56VDC by the vehicle charger 304 and output to the backup battery 100 to charge the backup battery 100 and provide power to the charging inverter U3. At the same time, the operating temperature of the vehicle charger 304 rises steadily, and the vehicle charger cooling fan 303 cools the vehicle charger 304. Then, the charging inverter U3 converts the power provided by the backup battery 100 and the chassis generator into 220VAC and outputs it to the power output interface U4. Finally, the power output interface U4 outputs the power to the temperature and humidity system of the tool warehouse vehicle.

[0035] It should be noted that in this utility model, the spare battery 100 has a specification of 48V / 400AH, the vehicle charger 304 has a specification of 24V charging 48V 5A, and the chassis battery G3 has a specification of 24V / 100AH.

[0036] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
