Description

[Technical field]

[0001] The present invention relates to the field of battery charging systems with compatible connection devices, and more particularly to a battery connection device, a charging connection device, a rechargeable battery, a charging device and a battery charging system whose battery management function can be upgraded and which can meet compatibility demands. [Background technology]

[0002] Radio-controlled (RC) model equipment, such as vehicle models and flight models, require the deployment of independent rechargeable batteries to power and operate. The variety of RC model equipment increases the types of batteries required. Compatible charging devices for different types of batteries have appeared on the market. For example, the battery chemistry type may be Metal Hydride / Nickel (MH-Ni) batteries, ternary lithium (Li-Ni-Mn-O) batteries, polymer lithium (LiPo) batteries, lead acid batteries, etc.

[0003] Batteries with different chemical types have greatly different charging and discharging characteristics. For example, the charging curve of a MH-Ni battery has two charging potential platforms, so users need to set the battery's chemical type in the charging device when charging, and the charging device needs to adjust the charging mode corresponding to the battery's chemical type. If users perform improper operation and select a charging mode that does not match the battery's chemical characteristics, it will easily shorten the battery's life and cause damage to the battery.

[0004] In order to realize the charging equipment to automatically identify the characteristics of the battery, the solution used in the prior art is to use a battery management system (BMS). The battery management system is provided in the battery and has many functions, such as evaluating the charge state of the battery, dynamically monitoring the working state, and balancing the monomer battery. These batteries are expensive, have complex functions, and cannot adapt to the rich characteristics of the battery types in the field of model equipment. Another solution in the prior art is to provide a printed label on the battery and have the terminal photograph it to obtain the battery information, or provide a radio frequency label on the battery and a radio frequency identification module on the charging equipment to obtain the battery information. These aspects require the user to increase the charging operation and adopt updated equipment, so they are often incompatible with conventional batteries or charging equipment.

[0037] In order to better explain the objectives, technical solutions and advantages of the present invention, the specific embodiments of the present invention are described in more detail below in conjunction with figures and examples. The following examples are used to explain the present invention, but are not used to limit the scope of the present invention.

[0038] Example 1 As shown in Fig. 1, the battery connection device according to the first embodiment of the present invention includes a first connection body A2. The first connection body A2 includes a first base A23, a first insertion structure A231, a first contact A21, a second contact A22 and a tip A3. The first insertion structure A231 is provided at the front end of the first base A23, and the first contact A21 is provided on the first insertion structure A231 along the insertion direction, and is used to generally insert and connect the lead-out end of the battery to a charging device or an electric device. In other words, the first insertion structure A231 can be inserted into another insertion part that is combined with it.

[0039] These insertion parts have a standardized insertion structure for a general charging device or electrical device. The second contact A22 is electrically connected to the chip A3 and is used to connect the pin of the chip A3 to the charging device or electrical device to realize the set function of the chip A3. The second contact A22 may be fixed to the first base A23 or may be movable within a predetermined range relative to the first base A23.

[0040] In the first embodiment, specifically, in the installation form in which the second contact A22 is fixed, the front end of the second contact A22 is located behind the rear end of the first insertion structure A231 in the insertion direction. As can be seen from this, in the process in which the first insertion structure A231 is inserted and fitted by an insertion part of a charging device or an electric device, the front end of the second contact A22 does not extend into the radial space of the first insertion structure A231, so it does not interfere with the first insertion structure A231.

[0041] In the first embodiment, specifically, in the installation form in which the second contact A22 is movable, the front end of the second contact A22 can move between the front end and the rear end of the first insertion structure A231 in the normal state, and in the process in which the first insertion structure A231 is inserted and fitted by an insertion part of a charging device or an electric device, the front end of the second contact A22 moves to the rear side of the rear end of the first insertion structure A231 according to the user's operation or insertion movement. The second contact A22 is displaced from the radial space of the first insertion structure A231 during insertion, so it does not constitute an obstruction to the first insertion structure A231.

[0042] The battery connection device of the first embodiment is disposed in a rechargeable battery, and in use, the rechargeable battery can be inserted and conductively connected to a conventional charging device or electrical device through the first insertion structure A231 of the first connection body A2, as shown in Fig. 1. The rechargeable battery also simultaneously realizes a functional connection between the chip A3 and the charging device through the second contact A22 of the first connection body A2.

[0043] Continuing to refer to FIG. 1, a charging connection device according to a first embodiment of the present invention is shown. The charging connection device is disposed in a charging device, the charging device includes a charging circuit A4, and the charging connection device includes a second connection body A5. The second connection body A5 is used to be fitted and inserted into the battery connection device of the first embodiment. The second connection body A5 includes a second base A53, a second insertion structure A531, a third contact A51, a processor A41, an additional insertion structure A532, and a fourth contact A52. The second insertion structure A531 is provided on the second base A53, and the third contact A51 is provided in the second insertion structure A531 and is electrically connected to the charging circuit A4, and is used to receive a battery with a conventional interface.

[0044] As can be seen, the battery connection device of the first embodiment can be inserted into the second insertion structure A531 through its first insertion structure A231. The additional insertion structure A532 is provided on the second base A53 and is located outside the insertion direction of the second insertion structure A531. The fourth contact A52 is provided in the additional insertion structure A532 along the insertion direction and is conductively connected to the processor A41 in the charging circuit A4. Since the additional insertion structure A532 is located on one side of the second insertion structure A531, a battery having a conventional interface can be inserted without any hindrance and achieve the charging function. The battery connection device of the first embodiment is inserted into a charging device and simultaneously achieves the charging function and the function of the chip A3.

[0045] As shown in FIG. 2, in the first embodiment, the rechargeable battery is an RC model battery. The RC model battery is composed of three battery monomers A11, and is provided with a power connection end A12 and a balancing connection end A13. The power connection end A12 is drawn from the positive and negative electrodes of the battery body A1, respectively, and is used for charging by a charging device and for supplying power to the RC model. The balancing connection end A13 is drawn from the node of each battery monomer A11 in the battery body A1. In the battery connection device in the first embodiment, each first contact A21 is connected to the balancing connection end A13 of the battery body A1 in one-to-one correspondence. In other words, the battery connection device is a connector for balancing charging of a battery.

[0046] As shown in FIG. 2, the chip A3 in this embodiment is a memory, and stores parameter information related to the battery body A1. The parameter information may be parameter information of a unique identification code, battery capacity, number of monomers, or chemical type of the battery, etc. The charging device automatically selects a corresponding charging mode based on the acquired parameter information, thereby exempting the user from setting the charging device. Furthermore, the chip A3 has a first pin A31 and a second pin A32. The first pin A31 is a data end for transmitting data, i.e., a DATA end. The second pin A32 is a ground end for grounding the circuit, i.e., a GND end.

[0047] The second contact A22 is electrically connected to the first pin A31 of the chip A3, and the second pin A32 of the chip A3 is electrically connected to the first contact A21 marked with "1(-)", which is electrically connected to the node of the negative electrode of the battery body A1, and the second pin A32 of the memory is electrically connected to the negative electrode of the battery body A1. When the rechargeable battery is inserted into the charging device, the ground terminal of the processor A41 is connected to the negative electrode of the balancing connection terminal A13 of the battery body A1, so that the chip A3 can be connected to the second pin A32 of the chip A3 through the first contact A21 marked with "1(-)", thereby eliminating the need for more independent second contacts A22, and achieving the purpose of saving the number of terminals and reducing the size of the connector.

[0048] As can be seen from this, in Example 1, by providing the chip A3 in the battery connection device, not only can the functions of the chip A3, such as storing parameter information and the charging equipment automatically selecting a charging mode based on the parameter information, be realized, but the battery connection device is also compatible with conventional charging equipment, electrical equipment and batteries.

The fourth contact A52 is provided in the additional insertion structure A532. The four third contacts A51 are conductively connected to the charging circuit A4. The fourth contact A52 is conductively connected to the processor A41. The front end of the fourth contact A52 is located in front of the front end of the third contact A51.

[0051] As can be seen, the second contact A22 is fixedly provided at the rear side of the first insertion structure A231, thereby preventing the second contact A22 from interfering with the first insertion structure A231 being inserted into the conventional charging interface 92. The fourth contact A52 is provided at the additional insertion structure A532, thereby preventing the fourth contact A52 from interfering with the second insertion structure A531 receiving the conventional battery interface 91. In addition, the front end of the fourth contact A52 is located forward and can be fitted into the second contact A22 to make conductive contact.

The second insertion structure A531 of the second connecting body A5 can be fully inserted into the conventional battery interface 91, and each of the third contacts A51 can charge the battery through the conventional battery interface 91. The additional insertion structure A532 is only provided on one side of the second base A53 and does not interfere with the insertion operation of the conventional battery interface 91.

[0054] Aspect 2 of Example 1 As shown in FIG. 6, this is a charging connection device according to the second embodiment of this embodiment. The first connection body A2 includes a first base A23, a first insertion structure A231, a first contact A21, a second contact A22, an insert A84, a second conductor A85, and a chip A3.

The insert body A84 can move within the length range of the second conductive wire A85, can move to the rear side of the rear end of the first insertion structure A231, and can be inserted into the second connection body A5 when the first connection body A2 and the second connection body A5 are inserted into each other.

In addition, the rechargeable battery not only conductively connects the balancing connection end B13 to the charging device, but also conductively connects the memory module B30 to the processor B41 of the charging device, and the parameter information such as the unique identification code, battery capacity, number of monomers or chemical type of the battery in the memory module B30 is provided to the processor B41, and the processor B41 automatically selects the charging mode, so that the user does not need to operate the charging device to manually select the charging mode.

[0070] When a user has the rechargeable battery of this embodiment but does not have the charging device of this embodiment, the user can plug and connect the first connector B2 with the conventional charging interface 92 to charge, and the extension structure B232 of the first connector B2 does not constitute an obstacle to the plugging. When a user has the charging device of this embodiment and also has another conventional battery, the user can plug and connect the conventional battery interface 91 of the battery with the second connector B5, manually set the battery parameters, and charge.

[0071] It can be understood that, according to another embodiment of the present invention, the rechargeable battery may further use a female insertion structure. Correspondingly, the charging device of this embodiment may further use a male insertion structure. According to another embodiment of the present invention, the storage module B30 may further be provided at the power connection end B12, instead of the balancing connection end B13 in this embodiment, and accordingly, the extension structure B232 is provided at the corresponding battery interface, and the expansion structure B532 is provided at the corresponding charging interface. According to another embodiment of the present invention, the first connector B2 may be integrally provided on the battery body B1, instead of being connected via the conductor B15 in this embodiment.

[0072] As can be understood, according to other embodiments of the present invention, the third contacts B51 in the charging device may be provided in more than four numbers, for example, the second connector B5 may be provided with seven third contacts B51, which can be adapted to a battery body B1 having 2-6 monomers.

[0073] The battery charging method of the second embodiment can be applied to a battery charging system, which includes a rechargeable battery provided with a first connector B2 and a charging device provided with a second connector B5. The battery charging method includes providing the rechargeable battery with a storage module B30, in which parameter information, such as a unique identification code, a battery capacity, a number of monomers, or a chemical type of the battery, is pre-stored. The charging device is configured to adjust the charging power according to the parameter information. The first connector B2 and the second connector B5 are configured to provide the parameter information in the storage module B30 to the charging device when they are plugged into each other. The first connector B2 is further configured to be plugged into another charging interface that does not have a terminal for transmitting the parameter information. The second connector B5 is plugged into another battery interface that does not have a terminal for transmitting the parameter information.
