Abstract
The utility model relates to an accumulator with balanced charging and discharging. The accumulator comprises an accumulator shell, an electrode plate cathode and an electrode plate anode which are arranged in the accumulator shell, a pole anode and a pole cathode which are arranged above the accumulator shell; a voltage detection chip is electrically connected between the electrode plate cathode and the electrode plate anode, the voltage detection chip is connected with a singlechip, on-off devices are respectively arranged between the pole anode and the electrode plate anode and between the pole cathode and the electrode plate cathode, and are electrically connected with the singlechip; when the accumulator is charged or discharged, the voltage detection chip can be used for monitoring a voltage value of the accumulator in real time, when the voltage is excessively high or excessively low, the on-off device is controlled by the singlechip to turn off the connection between the pole anode and the electrode plate anode and between the pole cathode and the electrode plate cathode, so as to stop the charging or discharging of the accumulator, the condition that the service life of the accumulator is shortened caused by overcharging or overdischarging is effectively avoided, and the accumulator is protected.
Description
Technical field
The utility model relates to the battery technology field, is specifically related to a kind of storage battery.
Background technology
The batteries of electric motor car is interconnected and is formed by the polylith storage battery, therefore when discharging and recharging, can cause and discharge and recharge inhomogeneous situation generation.When charge in batteries is not enough, the lead sulfate of negative and positive two-plate can not transform fully and become spongy lead and lead oxide, if long-term undercharge can cause the lead sulfate crystallization, makes plate vulcanizing, and it is bad that battery quality becomes.If instead battery overcharges, the amount of oxygen that anode produces is greater than the adsorption capacity of negative electrode, makes accumulator internal pressure increase, and causes gas excessive, and electrolyte reduces, and also may cause active material soften or come off, and battery life shortens greatly.
Summary of the invention
The utility model is in order to overcome the deficiency of above technology, provides a kind of and prevented from overcharging or the charge less electricity causes the life of storage battery to shorten discharges and recharges the balance storage battery.
The utility model overcomes the technical scheme that its technical problem adopts:
Originally discharge and recharge the balance storage battery, comprise accumulator housing, be installed on battery lead plate negative pole in accumulator housing and battery lead plate is anodal, the pole positive pole and the pole negative pole that are installed on the accumulator housing top, be electrically connected with voltage checking chip between described battery lead plate negative pole and battery lead plate positive pole, described voltage checking chip is connected in single-chip microcomputer, between the anodal and battery lead plate positive pole of described pole and be provided with on-off system between pole negative pole and battery lead plate negative pole, described on-off system is electrically connected on single-chip microcomputer.
Above-mentioned on-off system is normally opened relay I and normally opened relay II, the control end of described normally opened relay I and normally opened relay II is connected in single-chip microcomputer, described battery lead plate negative pole and battery lead plate positive pole are connected to the input of normally opened relay II and normally opened relay I, and described pole negative pole and pole positive pole are connected to the output of normally opened relay II and normally opened relay I.
The beneficial effects of the utility model are: when accumulator cell charging and discharging; voltage checking chip can the Real-Time Monitoring storage battery magnitude of voltage; when overtension or when too low; the Single-chip Controlling on-off system cut off between anodal and battery lead plate positive pole and pole negative pole and battery lead plate negative pole between be connected; thereby stop charging or the discharge process of storage battery; the situation generation of effectively avoiding storage battery to overcharge or discharging and cause the lost of life, realized the protection to storage battery.

In figure, 1. anodal 8. normally opened relay I of anodal 3. voltage checking chip 4. normally opened relay II 5. pole negative pole 6. battery lead plate negative pole 7. battery lead plates of accumulator housing 2. poles.
Embodiment
Below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing, be described further.
Originally discharge and recharge the balance storage battery, comprise accumulator housing 1, be installed on battery lead plate negative pole 6 and battery lead plate positive pole 7 in accumulator housing 1, be installed on pole anodal 2 and the pole negative pole 5 of accumulator housing 1 top, be electrically connected with voltage checking chip between described battery lead plate negative pole 6 and battery lead plate positive pole 7, described voltage checking chip is connected in single-chip microcomputer, between described pole anodal 2 and battery lead plate positive pole 7 and be provided with on-off system between pole negative pole 5 and battery lead plate negative pole 6, described on-off system is electrically connected on single-chip microcomputer.When accumulator cell charging and discharging; voltage checking chip can the Real-Time Monitoring storage battery magnitude of voltage; when overtension or when too low; the Single-chip Controlling on-off system cut off anodal 2 with battery lead plate positive pole 7 between and being connected between pole negative pole 5 and battery lead plate negative pole 6; thereby stop charging or the discharge process of storage battery; the situation generation of effectively avoiding storage battery to overcharge or discharging and cause the lost of life, realized the protection to storage battery.
Above-mentioned on-off system is normally opened relay I 8 and normally opened relay II 4, the control end of described normally opened relay I 8 and normally opened relay II 4 is connected in single-chip microcomputer, described battery lead plate negative pole 6 and battery lead plate positive pole 7 are connected to the input of normally opened relay II 4 and normally opened relay I 8, and described pole negative pole 5 and pole positive pole 2 are connected to the output of normally opened relay II 4 and normally opened relay I 8.Normally opened relay I 8 and normally opened relay II 4 can keep when flat between pole anodal 2 and battery lead plate positive pole 7 and pole negative pole 5 and battery lead plate negative pole 6 in conducting state, when overcharging or during feed condition, single-chip microcomputer can be controlled.Normally opened relay I 8 and normally opened relay II 4 disconnects being connected between poles anodal 2 and battery lead plate anodal 7 and pole negative pole 5 and battery lead plate negative pole 6, thereby the purpose of storage battery is protected in realization.Simple in structure, use reliable.
