Abstract
The utility model discloses an automatic switching control device for multi-set batteries of electric bicycles, and comprises at least two sets of battery packs, wherein anode of each battery pack is accessed into a controller through an one-way conductive diode, and cathode of each battery pack is connected to an OUT (output end) respectively through an electronic switch controlled by the controller; and the controller is composed of a power supply circuit and a control chip. The automatic switching control device prevents tedious operation caused by manually replacement of the batteries after the number of the batteries is increased, and thus improves riding continuity for users. The device can automatically switch at power shortage, prevent over discharge of the batteries, and improve battery life.
Description
Technical field
The utility model relates to the electric bicycle electronic applications, particularly the dedicated control device of the many Battery packs automatic switchovers of a kind of electric bicycle.
Technical background
Electric bicycle is for obtaining longer distance travelled, and the most frequently used way is to increase battery capacity at present.When battery capacity increases, also increased battery weight.In order to make battery dismounting or carrying easily, generally be that high capacity cell is divided into two groups or three groups of small-capacity cells groups, the user in use, the mileage of riding the same day on the estimation decides and carries several Battery packs trips.When carrying many Battery pack trips, after a Battery pack power drain, needing the people is the battery pack of closing power drain, the battery of sufficient electric power is closed on the loop of motor and electric machine controller.
The utility model content
The purpose of this utility model is for the technological deficiency that exists in the prior art, and a kind of many Battery packs of electric bicycle automatic switching control device is provided.
For realizing that the technical scheme that the purpose of this utility model adopts is: a kind of many Battery packs of electric bicycle automatic switching control device, it is characterized in that, comprise at least two Battery pack groups, every Battery pack group is anodal by unilateal conduction diode access controller, and every Battery pack group negative pole is connected to the OUT(output by the electronic switch that is controlled by the controller respectively); Described controller is comprised of power supply circuits and control chip.
Compared with prior art, the beneficial effects of the utility model are:
Avoid increasing in the past and change the troublesome operation that battery brings by hand after the number of batteries, improve user's continuity of riding.Short of electricity is automaticallyed switch, and prevents the battery over-discharge can, improves battery life.
Description of drawings
Fig. 1 is the schematic diagram of the utility model as an example of three battery pack example.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Introduce the switch controller principle as an example of three battery pack example, as shown in Figure 1:
B1, B2, B3 are respectively three Battery packs, and it is anodal by unilateal conduction diode access controller.Its negative pole is connected to OUT-(output) by controlled electronic switch respectively.CT represents in-line power unit and the control unit of controller in the diagram.Three dotted lines of CT below represent the control line of connecting electronic switch.OUT+, OUT-represent the respectively positive and negative electrode of controller output end.
Any Battery pack has in the situation of electricity, can power to CT, and CT one has electricity, and at first the electronic switch of conducting B1 below judges whether B1 is under-voltage, as not under-voltage, and then externally output.If B1 is under-voltage or battery pack does not exist, then close electronic switch corresponding to B1.
According to B1, B2, the order of B3 is judged battery voltage successively, such as not under-voltage then externally output, does not pack into such as under-voltage or battery pack, then closes corresponding electronic switch, changes next battery pack over to.
When the voltage of three battery pack does not satisfy service condition, then closeall electronic switch stops output.
