Abstract
A novel floating charging circuit using silicon controlled rectifiers is disclosed. The circuit is characterized in that a positive electrode of an isolation-type charging power supply (P) is connected with an anode of a first silicon controlled rectifier (S1); a cathode of the first silicon controlled rectifier (S1) is connected with a positive electrode of a charging cell (B); a negative electrode of the charging cell (B) is connected with an anode of a second silicon controlled rectifier (S2); a cathode of the second silicon controlled rectifier (S2) is connected with a negative electrode of the isolation-type charging power supply (P); control electrodes of the first silicon controlled rectifier (S1) and the second silicon controlled rectifier (S2) are control terminals; conduction and shut off of a charging loop are controlled through controlling conduction and shut off of the two silicon controlled rectifiers. Because the negative electrode of the cell can be floated, the circuit can be directly connected to any single cell in a series battery pack so as to charge the cell.
Description
Technical field
The utility model relates to a kind of employing silicon controlled floating charge circuit.This circuit is connected to the isolated form charge power supply on rechargeable battery by two controllable silicons, controls the turn-on and turn-off of charge circuit by controlling two silicon controlled turn-on and turn-off.Because battery cathode can be floated, so can directly being connected in series battery, this circuit on cell, this battery is charged arbitrarily.
Background technology
Rechargeable battery, as lithium battery, lead-acid battery etc., when series connection is used in groups, need to do charge maintenance to certain joint cell wherein.The general manual method that adopts is carried out charge maintenance to cell.That but this method exists is time-consuming, effort, cost are higher, and the shortcoming of easily makeing mistakes.
Summary of the invention
For time-consuming, the effort that overcomes that each cell of existing charge maintenance battery pack exists, the shortcoming that cost is higher, the utility model provides a kind of floating charge circuit, coordinates controller to be used for each cell in automatic charging battery maintenance group.
The utility model solves the technical scheme that its technical problem adopts: the positive pole of isolated form charge power supply (P) connects the anode of the first controllable silicon (S1), the first controllable silicon (S1) negative electrode connects the positive pole of rechargeable battery (B), the negative pole of rechargeable battery (B) connects the anode of the second controllable silicon (S2), the negative electrode of the second controllable silicon (S2) connects the negative pole of isolated form charge power supply (P), and the control of the first controllable silicon (S1) and the second controllable silicon (S2) is control end very.
The beneficial effects of the utility model are that circuit structure is simple, cheap.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic diagram of the present utility model.
In Fig. 1, P is the isolated form charge power supply, and S1 is the first controllable silicon, and S2 is the second controllable silicon, and B is rechargeable battery, 1. the control utmost point of the first controllable silicon (S1), 2. the control utmost point of the second controllable silicon (S2).
Embodiment
In Fig. 1, the positive pole of isolated form charge power supply (P) connects the anode of the first controllable silicon (S1), the first controllable silicon (S1) negative electrode connects the positive pole of rechargeable battery (B), the negative pole of rechargeable battery (B) connects the anode of the second controllable silicon (S2), the negative electrode of the second controllable silicon (S2) connects the negative pole of isolated form charge power supply (P), and the control of the first controllable silicon (S1) and the second controllable silicon (S2) is control end very.
While giving rechargeable battery (B) charging, at first, isolated form charge power supply (P) is opened, after 1., 2. inputting start signal, the first controllable silicon (S1) and the second controllable silicon (S2) conducting, isolated form charge power supply (P) is charged to rechargeable battery (B) by the first controllable silicon (S1) and the second controllable silicon (S2).After isolated form charge power supply (P) is closed, the first controllable silicon (S1) and the second controllable silicon (S2) are closed, and isolated form charge power supply (P) is no longer charged to rechargeable battery (B).
