The application provides a kind of method for protecting battery;The application also provides a kind of protection battery Device.It is described in detail one by one in the following embodiments.
To first embodiment provided by the present application, i.e., a kind of embodiment for the method for protecting battery.
The present embodiment is described in detail below with reference to Fig. 1, wherein Fig. 1 is protection electricity provided by the embodiments of the present application The flow chart of the method for pond service life.
Step S101 obtains the fisrt feature information of battery.
Battery refers to and fills electrolyte solution and metal electrode to generate the cup of electric current, slot or other containers or clad vessel Segment space, chemical energy can be converted to the device of electric energy.Point with anode, cathode.With the development of science and technology battery is general Refer to the midget plant that can be produced electricl energy.Such as solar battery.The performance parameter of battery mainly have electromotive force, capacity, specific energy and Resistance.Energy source is utilized the battery as, it is available that there is burning voltage, stabling current, long-time stable power supply, by the external world The electric current of very little is influenced, and battery structure is simple, easy to carry, charge and discharge are easy to operation, not by outside climatic and temperature The influence of degree, stable and reliable for performance, the various aspects performance in modern society's life has great role.
Currently, very universal using rechargeable battery in fields such as intelligent electronic device, Rechargeable vehicles.
Step S102, judges whether the fisrt feature information meets default high temperature and pressure protective condition.
The fisrt feature information, comprising: supplying power for outside information, information of voltage, temperature information and high temperature and pressure time letter Breath.
The supplying power for outside information, the information of electric current is externally exported including the battery.
The information of voltage refers to the current cell voltage of the battery.
The temperature information refers to the current temperature information of the battery.The temperature is not due to battery work and generates Heat causes the temperature of the battery to increase, but heat is conducted to the battery by heat exchange pattern by environment temperature Bring temperature increases.For example, solar energy is conducted to the battery and bring temperature liter under the direct irradiation in sunlight It is high.
The high temperature and pressure temporal information refers to that in the case where the battery supplying power for outside, the voltage of the battery reaches The duration of default protection temperature condition is reached to the temperature of default protection voltage conditions and the battery.
It is described to judge whether the fisrt feature information meets default high temperature and pressure protective condition, comprising:
Judge whether the supplying power for outside information of the battery meets predetermined current condition.
The supplying power for outside information of the battery includes the current information of the supplying power for outside of the battery.

Step S102-2 protects acquisition of information second voltage information according to the first voltage information and predeterminated voltage.
The predeterminated voltage protects information, is in order to provide a voltage protection range to the battery, so as to the electricity When pond is in the protection scope, the battery is protected in preparation, that is, discharge operation.
The second voltage information, that is, the difference of the first voltage information and predeterminated voltage protection information.
For example, the predeterminated voltage protection information is 0.2V, when the battery is full of voltage (the i.e. described first voltage letter Breath) when being 5V, then the second voltage information is 4.8V (5V-0.2V=4.8V).
Step S102-3, judges whether the information of voltage of the battery is greater than the second voltage information.
For example, continuing the example above, voltage of the present embodiment to the information of voltage of the battery greater than 4.8V is as guarantor Guard strip part.
It is described to judge whether the fisrt feature information meets default high temperature and pressure protective condition, comprising:
Judge whether the temperature information of the battery meets default protection temperature condition.For example, the default protection temperature Condition are as follows: the temperature information of the battery is greater than 45 DEG C.
It is described to judge whether the fisrt feature information meets default high temperature and pressure protective condition, comprising:
Judge whether the high temperature and pressure temporal information of the battery meets default guard time condition.For example, continuing above-mentioned Example, the battery meets the following conditions: the current information of the lasting supplying power for outside of the battery is greater than 0.1 ampere, and works as The battery full of voltage be 5V when, the information of voltage of the battery is greater than 4.8V, and the temperature information of the battery is greater than 45℃;Start calculating prolongeding time on the basis of meeting above three condition, when the duration (height of the i.e. described battery Warm high-voltage time information) be greater than 24 hours, then protection operation, i.e. discharge operation are carried out to the battery.
Step S103, if so, discharging according to preset rules the battery.
The preset rules will exactly discharge to the battery, its voltage is made to enter security interval, thus alleviate because The rapid attenuation and own vol of battery caused by high temperature and pressure expand, and extend the service life of battery, reduce because For security risk caused by expansion.
Preferably, the battery, including the battery pack with equalizing circuit.
The battery pack with equalizing circuit, is made of multiple battery units and equalizing circuit.It is present battery development Main flow direction, for example, Notebook Battery, batteries of electric automobile etc..The battery pack will appear the electricity in use The inconsistency of voltage between pool unit, the inconsistency be cause the battery performance decline an important factor for, it is unbalanced The battery pack can reduce the capacity of the battery pack and the utilization rate of energy, it is horizontal to reduce battery pack input-output power, Shorten the service life of battery pack.In order to improve the consistency in each battery unit use process, need by described equal The circuit that weighs carries out balanced management to the voltage of the battery unit.
It is preferably, described to discharge according to preset rules the battery, comprising:
It is discharged using the equalizing circuit the battery pack according to the preset rules.
Further, described to be discharged using the equalizing circuit the battery pack according to the preset rules, packet It includes:
