Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 3, the present invention discloses a charging device 100 for charging a single-voltage battery pack or a multi-voltage battery pack plugged into a charging interface of the charging device 100. The charging device 100 includes a voltage transforming unit 10, a first charging unit 20, a second charging unit 30, a switching unit 40, and a control unit (not shown).
Referring to fig. 3, the transformer unit 10 is used to be connected to an external power source to obtain power and convert the power into a required voltage. Trunk lines 11 are arranged on two sides of the voltage transformation unit 10. One end of the trunk line 11 is connected to the voltage transformation unit 10, and the other end is connected to the first charging unit 20 and the second charging unit 30. The main line 11 is further provided with a sixth switch 111, so that the sixth switch 111 controls the on/off between the voltage transformation unit 10 and the first charging unit 20 and the second charging unit 30. Thereby improving the safety performance of the charging device 100.
Referring to fig. 3, the first charging unit 20 is connected to the trunk line 11, and includes a first terminal group 21 connected to a first battery cell group of a battery pack, a first switch 22, a second switch 23 and an isolation diode 24 located at two sides of the first terminal group 21. The first switch 22, the isolation diode 24, the first terminal set 21, and the second switch 23 are sequentially connected to the trunk 11. The first terminal set 21 includes a first positive pole 211 and a first negative pole 212, and the isolation diode 24 is located between the first switch 22 and the first positive pole 211, that is: the isolation diode 24 is located on a side of the first terminal set 21 facing away from the negative pole. Of course, in other embodiments, the isolation diode 24 may also be disposed on a side of the first terminal set 21 facing away from the anode. The second charging unit 30 is connected to the transforming unit 10, and includes a second terminal set 31 for connecting with a second cell set of a battery pack, a third switch 32 located at one side of the second terminal set 31, and an isolation diode 34. The third switch 32, the isolation diode 34 and the second terminal set 31 are sequentially connected to the trunk 11. The second terminal set 31 includes a second positive pole 311 and a second negative pole 312, the isolation diode 34 is located between the third switch 32 and the second positive pole 311, that is: the isolation diode 34 is located on a side of the second terminal set 31 facing away from the negative electrode. In this embodiment, the third switch 32 is located on a side of the second terminal set 31 facing away from the negative electrode, but in other embodiments, the third switch 32 may also be located on a side of the second terminal set 31 facing away from the positive electrode. The first terminal set 21 and the second terminal set 31 together form a charging interface or a part of the charging interface of the charging device 100. The isolation diodes 24 and 34 are used for limiting the flow direction of current to prevent the first switch 22, the second switch 23, the third switch 32 and the switching unit 40 from causing short circuit of the battery pack during state switching, thereby causing damage to the battery pack, the switch and the switching unit 40. The first switch 22, the second switch 23, the third switch 32 and the sixth switch 111 may be magnetic relays, MOS transistors or insulated gate bipolar transistors.
Referring to fig. 3, the switching unit 40 includes a first switch 41. The first switch 41 has one end connected to the first cathode 212 of the first terminal group 21 and the other end connected to the first anode 311 of the second terminal group 31. Of course, in other embodiments, it may also be configured to: the first switch 41 has one end connected to the first positive electrode 211 of the first terminal group 21 and the other end connected to the first negative electrode 312 of the second terminal group 31. The control unit communicates with the battery pack to acquire internal information of the battery pack inserted into the charging interface, and controls the first switch 22, the second switch 23 and the third switch 32 to operate according to the internal information, so that the first charging unit 20 and the second charging unit 30 operate in series or in parallel. The internal information comprises type information of the battery pack, charging requirements, rated charging voltage information and rated charging current information. The type information is used to indicate that the battery pack is a single-voltage battery pack, a multi-voltage battery pack, or the like. The charging requirement is used for indicating that the multi-voltage battery pack needs to charge a plurality of battery cell groups in series or charge a plurality of battery cell groups in parallel. The control unit controls the voltage output by the voltage transformation unit 10 to be the rated charging voltage according to the acquired rated charging voltage information.
Preferably, the trunk 11 is further provided with a trunk flow detection element (not shown). When the current detected by the main current detecting element is greater than the rated charging current, the control unit controls the charging device 100 to stop working or limit the current. Further, the first charging unit 10 is further provided with a first current detecting element, and the second charging unit 20 is further provided with a second current detecting element. When the current detected by the first current detecting element or the second current detecting element is larger than the maximum current allowed to pass through the first charging unit 20 or the second charging unit 30, the control unit controls the first charging unit 20 or the second charging unit 30 to stop working or limit current.
When the charging device 100 is used, the battery pack is first inserted into the charging interface. The control unit communicates with the battery pack to acquire internal information of the battery pack. When the inserted battery pack is detected to be a single-voltage battery pack, the control unit controls the voltage transformation unit 10 to output the rated charging voltage of the battery pack, and then controls the sixth switch 111, the first switch 22 and the second switch 23 to be closed, and controls the first switch 41 and the third switch 32 to be opened, so that the first charging unit 20 charges the battery pack. At this time, the actual operation circuit can be simplified as shown in fig. 4. When it is detected that the inserted battery pack is a multi-voltage battery pack, if the battery pack needs to be charged in series, the control unit controls the sixth switch 111, the first switch 22 and the first switch 41 to be closed, and the second switch 23 and the third switch 32 to be opened, so that the first charging unit 20 and the second charging unit 30 are connected in series, and at this time, an actual working circuit is as shown in fig. 5; if the battery pack needs to be charged in parallel, the control unit controls the sixth switch 111, the first switch 22, the second switch 23, and the third switch 32 to be closed, and the first switch 41 to be opened, so that the first charging unit 20 and the second charging unit 30 are connected in parallel, and at this time, an actual operating circuit is as shown in fig. 6.
Compared with the prior art, the charging device 100 not only can charge single-voltage battery packs with different voltages, but also can charge multi-voltage battery packs with different voltages, and can automatically select a series or parallel charging mode according to the charging requirements of the multi-voltage battery packs, so that the maintenance difficulty and the use cost of a user are reduced, and the problem of damage to the charger and the battery packs caused by misuse of the charger can be effectively avoided.

The second charging unit 20 is further provided with a fourth switch 33 on the side of the second terminal set 31 facing away from the third switch 32. The switching unit 40 further includes a second switch 42. The second switch 42 has one end connected to the negative electrode of the second terminal group 31 and the other end connected to the positive electrode of the third terminal group 51.
