Problems solved by technology

Frequent plugging and unplugging of the connector will cause the contacts to be worn, oxidized or deformed and cannot be charged, and the exposed contacts of the connector will cause safety problems, making this type of battery pack unsuitable for use in some harsh environments, such as some Construction Site
Although some existing technologies use wireless power supply technology (also known as non-contact power supply technology) to charge the battery pack, it is usually the traditional low-frequency magnetic induction technology, which requires high alignment between the wireless power transmitter and the wireless power receiver.
The spatial freedom of the wireless power receiving end is low
This defect will be more prominent in certain application environments, such as drone take-off and landing, vehicles or workplaces with vibrations

Abstract

A battery pack and a wireless charging system using the battery pack are disclosed, a chargeable battery core, a charging circuit and a wireless electric energy receiving circuit based on magnetic resonance coupling are integrated as a whole, so that the battery pack can receive electric energy to charge the chargeable battery core in a wireless way, at the same time as the wireless electric energy receiving circuit is suitable for coupling with a wireless electric energy transmitting terminal in a magnetic resonance way, the wireless electric energy receiving circuit can receive the electric energy with a greater degree of spatial freedom, so that the battery pack has a greater degree of spatial freedom when in charging, and is convenient for users to use.

Description

technical field [0001] The present disclosure relates to power electronics technology, in particular to a battery pack and a wireless charging system. Background technique [0002] With the large-scale use of electronic mobile devices (mobile phones, wireless power tools, unmanned aerial vehicles, sweeping robots, smart wearable devices, etc.), rechargeable batteries are widely used. The rechargeable battery pack can be directly integrated in the electronic device, or can be detachably connected with the electronic device as an accessory, so as to supply power to the electronic device or prolong the battery life of the electronic device. [0003] Existing rechargeable battery packs need to form a physical electrical connection with a charger through wires and connectors for charging. Frequent plugging and unplugging of the connector will cause the contacts to be worn, oxidized or deformed and cannot be charged, and the exposed contacts of the connector will cause safety pro...
