Abstract
The utility model discloses a charge device for an emergent power, comprising a power, a triode, a comparator, a chip, a resistance, and etc.; all elements are arranged on a copper clad plate, connected with the other circuit parts in the emergent lamp into a whole, and arranged inside the emergent lamp; the device also comprises a timer consisting of one or a plurality of pieces of counters or a single chip to control charge time; the utility model has simple structure and can ensure the full charging of the chargeable battery.
Description
The utility model relates to a kind of battery charging circuit device, especially a kind of emergency power supply Ni-Cd battery charger that is applied to.
There are weak points such as too simple, that work is unreliable, battery can not be full of electricity fully, the charging interval is long in the emergency light live part of existing use Ni-Cd battery.Specifically, following several charging form is generally arranged at present: 1, constant voltage constant current charging; This charging circuit is fairly simple, economical, is suitable for the charging occasion of long-time little electric current.Its main shortcoming is: determine when relatively difficulty of complete charge, and battery is not easy also to be full of fully.2。Temperature control charging; This charging circuit relatively is suitable for quick charge, but its line cost is than higher, and will determine accurately that the difference of battery temperature and ambient temperature neither a nothing the matter in the middle of reality is used.3。Trickle charge.This charging circuit is quite simple, and shortcoming is that the charging interval is long and battery can not be full of fully.
The utility model is intended to propose a kind of inner charging circuit device that uses of emergency light that all relatively is fit on cost and performance; Overcome the deficiencies in the prior art, can in the short period of time battery be full of electricity fully, and cost is low, and reliability is high.
The technical solution of the utility model is achieved in that a kind of battery charging circuit device, comprise power supply, triode, comparator, counting chip, resistance etc., all elements are contained on the copper clad plate, link together with other circuit part in the emergency light and to constitute an integral body, place emergency light inside, be primarily characterized in that charging circuit device also comprises a timer.
As to further improvement of the utility model, charging circuit device also comprises a battery voltage detection part.
As to further improvement of the utility model, described timer is made of 1, multi-disc counter or single-chip microcomputer.
As to further improvement of the utility model, the charging current of rechargeable battery is between the 0.1C-0.13C.
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is first embodiment fundamental diagram of the present utility model;
Fig. 2 is first embodiment circuit diagram of the present utility model.
Fig. 3 is another embodiment fundamental diagram of the present utility model;
Fig. 4 is another embodiment circuit diagram of the present utility model.
As shown in drawings, battery charging circuit device comprises power supply, triode, comparator, counting chip, resistance, rechargeable battery etc., and all elements are contained on the copper clad plate, linking together with other circuit part in the emergency light constitutes an integral body, places emergency light inside.
In Fig. 1, first embodiment shown in Figure 2, U2, U3 constitute 22 grades of timer conters, and count pulse directly obtains from the AC power of 50Hz, from the 10 pin input of U2; C2, R20 constitute an electrify restoration circuit, are used for the power-on reset to U2, U3.When system had just begun to switch on, timer resetted and picks up counting; Timing generally was set in about 12 hours, and to the time of setting, 14 pin of U3 are exported a high level at once as timing, and 2 pin of U4A are closed constant-current source followed by being set to high level, stopped charging.
R1, Q2, Q3 constitute a constant-current source, a more stable charging current are provided for battery BT1, and its value size is generally got (C is a battery capacity value) between the 0.1C-0.13C; Can control charging current, R1 ≈ 0.6/I (I is a charging current) by the resistance of adjusting resistance R 1.The too little electricity that is not fully filled easily of electric current, electric current fills battery bad very much greatly easily.
U4A is a voltage comparator, is used to detect the terminal voltage that is recharged battery, if the terminal voltage of battery has risen to predefined value, then the output pin 2 of U4A is a high level, closes constant-current source, stops charging.
Present embodiment has guaranteed that with two counters and the dual control charging of battery voltage detection part rechargeable battery is full of fully.
In Fig. 3, second embodiment shown in Figure 4, U5 is 14 grades of binary counters, and R5, R6, C3 constitute a RC oscillator with U5, a count pulse is provided for U5 self.Battery charge is partly controlled by timer fully, has saved battery voltage detection part.
Because counter is cheap, thereby whole charging device cost is low, adds simple in structurely, has good market prospects.
Claims (6)
1, a kind of battery charging circuit device, comprise power supply, triode, comparator, counting chip, resistance, rechargeable battery etc., all elements are contained on the copper clad plate, link together with other circuit part in the emergency light and to constitute an integral body, place emergency light inside, be primarily characterized in that: charging circuit device also comprises a timer.
