Problems solved by technology

If the lithium-ion battery pack and the nickel-cadmium battery pack are applied to the emergency power supply of unmanned helicopters and other aircraft, if they are used separately, they will not only be bulky and take up a lot of space, but also increase the weight of the product, which increases the unnecessary power consumption of the whole machine. burden

Abstract

The invention relates to a power supply system and discloses an onboard mixing power supply system with which the requirements on high capacity and long endurance time are met, the space is reduced, and a lithium-ion battery pack and a cadmium-nickel battery pack are integrated. The system comprises a cadmium-nickel battery pack, a lithium-ion battery pack, a floating charging intelligent protecting plate, a power supply socket, a charging maintenance socket and an electronic adapter plate, wherein the cadmium-nickel battery pack is connected with the power supply socket and the electronic adapter plate; the lithium-ion battery pack is connected with the power supply socket and the electronic adapter plate through the floating charging intelligent protecting plate; the electronic adapter plate is connected with the power supply socket; and the charging maintenance socket is connected with the cadmium-nickel battery pack and the lithium-ion battery pack. The power supply system is applicable to aircrafts such as an unmanned helicopter or a small spy plane.

Description

technical field [0001] The invention relates to a power supply system, in particular to an airborne hybrid power supply system composed of a lithium-ion battery pack and a nickel-cadmium battery pack. Background technique [0002] Lithium-ion battery is a new type of high-energy battery, which has the characteristics of large specific energy, high working voltage, long cycle life, and small self-discharge. However, the high-current charge and discharge performance of lithium-ion batteries is relatively poor, and it cannot be used alone for high-power input applications. In contrast, nickel-cadmium batteries can be quickly charged with large currents, and can be quickly discharged to provide large currents for the load, and the voltage change is small during discharge. It is suitable for equipment that requires high power input such as engines, but nickel-cadmium batteries The capacity of the battery is low, the self-discharge is strong, and there is a serious memory effect. ...
