Description

The bottom plate and storage rack suitable for placing battery packs and the corresponding battery packs system

This work is about a base plate and a storage rack suitable for placing a battery set and a corresponding battery set; especially about a base plate and a storage rack with a wireless charging system and the corresponding battery set.

With the advancement of technology, people's demand for mobile batteries (eg, lithium batteries, aluminum-iron batteries, etc.) is also increasing. As demand increases, suppliers' storage management costs for batteries will also increase.

For example, due to its characteristics, the battery needs to maintain a certain percentage of power in order to maintain the quality of the battery. When the power in the battery is too low (for example, a self-discharge situation due to the internal impedance of the battery), it may lead to problems such as reduced battery life, reduced power storage, or even battery damage. Therefore, managers or suppliers need to constantly monitor the condition/charge of the battery, as well as actions such as charging it. However, when the number of batteries to be managed increases, the labor cost and time required by managers or suppliers will increase significantly.

In view of this, how to effectively improve the efficiency of managing the storage battery and how to maintain the battery's power in a low-cost and safe way will be a major challenge in the development of this field.

One of the goals of this creation is to improve the efficiency and safety of managing a large number of batteries.

This creation provides a bottom plate suitable for placing a battery set, including a bottom plate body, a transmitting coil group and a wireless power supply module. The transmitting coil group is arranged on the base plate body, so as to form a charging area on the plate surface of the base plate body and transmit magnetic signals toward the outside of the plate surface. The wireless power supply module is arranged adjacent to the base plate body. The wireless power supply module includes a power input terminal configured to introduce power from an external power supply terminal, a first control unit configured to adjust the power to output a first output power signal, and a first control unit coupled to the transmitting coil set output port. Wherein, the first output power signal is output from the first output port to the transmitting coil set to form a magnetic signal.

The present invention provides a storage rack suitable for placing battery sets, including the bottom plate and the rack body of the present invention. The object-bearing bottom plate is arranged in the frame body to form a plurality of storage spaces.

This creation provides a battery pack, which includes a battery and a wireless charging module. The wireless charging module includes a receiving coil set configured to receive a magnetic signal, a second control unit configured to conditionally process the magnetic signal and convert it into a second output power signal, and detachably coupled to a battery the second output port. The second output port outputs the second output power signal to the battery, so as to maintain the power of the battery above the threshold.

As mentioned above, through the wireless power supply module and the corresponding wireless charging module, the battery can maintain the power of the battery in a non-contact manner. In this way, the purpose of reducing the consumption of human resources and management costs is achieved.
