Embodiment
The present invention discloses a kind of supply unit, and this supply unit can be installed in mobile phone, (PersonalDigital Assistant PDA) waits in the electronic installation personal digital assistant, is used for to these electronic installation power supplies.
See also Fig. 1, this supply unit 100 comprises a battery 10, a detection module 20, a data processing module 30 and a switch module 40 that electrically connects successively.
This battery 10 can be an existing rechargeable battery, as lithium battery etc., it has a nominal operation temperature range that sets in advance and a rated capacity scope, and in this rated temperature range and rated capacity scope, described battery 10 can normally provide power supply for above-mentioned electronic installation.
This detection module 20 is used to detect the temperature of described battery 10 and the electric weight of storage.Described detection module 20 comprises a temperature detecting unit 22 and an electric weight detecting unit 24.Described temperature detecting unit 22 can be an existing temperature sensor, and itself and described battery 10 electrically connect, and be used to detect the temperature of described battery 10, and detected temperature value is delivered to described data processing module 30.This electric weight detecting unit 24 is used to detect the capacity of described battery 10 storages, and detected charge value is sent to described data processing module 30.
This data processing module 30 comprises a memory cell 32, a comparing unit 34 and a data processing unit 36.Store a default repid discharge temperature and a default repid discharge capacity in the described memory cell 32 respectively, described discharge temp and discharge capacity can be respectively the nominal operation temperature of above-mentioned described battery 10 and the maximum of rated capacity.This comparing unit 34 can be the comparable chip of LM2903 or other chip or the circuit with identical function for model, it is used for the charge value of described detection module 20 detected temperature values and storage and the discharge temp and the discharge capacity of memory cell 32 stored are compared respectively, and comparative result is transferred to described data processing unit 36.For example, need carry out repid discharge at battery 10, promptly when the electric weight of the temperature of described battery 10 and storage surpasses described discharge temp and discharge capacity respectively, described comparing unit 34 exportable is in order to express the signal of precarious position, data processing unit 36 as described in giving as a high level signal.And under other situation, battery 10 does not need to carry out repid discharge, as described in surpassing as the temperature of this battery 10 discharge temp or as described in electric weight surpass discharge capacity value, when perhaps both all surpass described preset range, described comparing unit 34 exportable is given data processing unit 36 in order to express the signal of safe condition as a low level signal.
These switch module 40 1 ends and described battery 10 and data processing unit 36 electrically connect, and other end ground connection is used to control this battery 10 and externally discharges.These switch module 40 initial conditions are closed condition, when it receives enabling signal from data processing unit 36, promptly when the electric weight of the temperature of described battery 10 and storage surpasses described discharge temp and discharge capacity value respectively, described switch module 40 is with conducting, thereby connect described battery 10, make described battery 10 ground connection to discharge its energy, thereby avoid battery 10 to produce expanding or blast externally to carry out repid discharge.
See also Fig. 2, the workflow of these supply unit 100 discharges may further comprise the steps:
Step S1: start described temperature detecting unit 22 and electric weight detecting unit 24, make described temperature detecting unit 22 and electric weight detecting unit 24 detect the temperature of battery 10 and the electric weight of storage respectively, and the charge value of detected temperature and storage is delivered to described data processing module 30 respectively.
Step S2: described comparing unit 34 is respectively with the temperature and the described discharge temp of described battery 10, and the electric weight and the discharge capacity of described battery 10 storages compare.
Step S3: described data processing unit 36 judges whether the temperature of described battery 10 and the electric weight of storage all meet or exceed default repid discharge temperature and repid discharge capability value, if, then enter step S4, if not, step S1 then returned.
