Description

Technical Field

[0001] The invention relates to the technical field of emergency power supply, and in particular to a multifunctional power supply device. Background Art

[0002] When vehicles of different models break down during field operations, multiple emergency power supplies may be required for maintenance operations, and traditional single voltage source batteries cannot meet this demand. Given that there are currently only three ways to solve the need for multiple power supply voltages in the field:

[0003] The first one is to carry emergency power supplies of various specifications and models, but this will bring a burden on the vehicle's storage space and cost.

[0004] The second method is to use high-power inverters and rectifiers. The corresponding problems are also obvious. High-power inverters are expensive, and there are many electronic components on the inverter and rectifier equipment, which are easy to burn out. Therefore, they are not suitable for outdoor use.

[0005] The third method is to carry multiple batteries of the same model and change the wiring by yourself to achieve the effect of outputting different power supply voltages. However, not everyone knows how to change the wiring and the operation is relatively troublesome and has certain risks.

[0006] Therefore, based on the above technical problems, technicians in this field urgently need to develop a multifunctional power supply device. Summary of the invention

[0007] The purpose of the present invention is to provide a multifunctional power supply device, which can change the internal wiring method by changing the matching relationship between the upper end cover and the cover plate to provide 12V, 24V, and 48V output voltages according to actual conditions. The power supply device has a novel structure and is easy to operate, which solves the problems existing in the prior art.

[0039] When a traditional battery is used or partially used and discharged, the voltage of each battery is not equal. Some batteries are fully charged while others are low. At this time, when you want to charge the low-power battery, uneven charging will occur, causing certain damage to the battery. This device will not have this phenomenon. The charging and discharging can freely switch the battery series and parallel, so as to achieve the effect of uniform charging and discharging. BRIEF DESCRIPTION OF THE DRAWINGS
