Embodiment
See also shown in Figure 2ly, it is the embodiment block schematic diagram for the battery coulometric detection device of portable electronic devices of the present invention.The portable electronic devices 2 of this embodiment can be a mobile phone, a personal digital assistant and a global positioning system one of them.Electronic installation 2 has a battery 21, and this battery 21 has an electric weight.The battery coulometric detection device comprises a display screen 22, a sensing element 23, a storage element 24 and a processing unit 25.
Wherein, temperature value 242 is preferably a temperature range value, as-10 degree-5 degree, 5 degree-15 degree, 15 degree-25 degree, 25 degree-35 degree, the above equitemperature scope of 35 degree, and the charge value 241 of each temperature value correspondence is to represent with percentage, as 70%, 80%, 90%, 100%, 110% etc., the wherein corresponding charge value 70% of temperature value-10 degree-5 degree, the corresponding charge value 80% of temperature value 5 degree-15 degree, the corresponding charge value 90% of temperature value 15 degree-25 degree, temperature value 25 degree-35 corresponding charge values 100% of degree and the above corresponding charge value 110% of temperature value 35 degree.These a little charge values 241 and temperature value 242 preferably store with a question blank (lookup table).
For example, the battery temperature that senses when sensing element 23 is 30 degree, it falls between temperature range 25 degree-35 degree, corresponding charge value 241 is 100%, so processing unit 25 is multiplied by 100% with the electric weight of battery 21, calculate this again and adjust back electric weight and the ratio value that is full of electric electric weight, again this ratio value is shown on the screen 22 with icon or digital form.The battery temperature that senses when sensing element 23 is 37 degree, then corresponding charge value 241 is 110%, its expression is because the relation that temperature raises, the electric weight of battery is estimated meeting many 10%, so electric weight can allow the user more know the true electric weight and the spendable time span of current battery than being high when 30 spend with the ratio value of the electric weight that is full of electricity thus after the adjustment when 35 spend.Similarly, the battery temperature that senses when sensing element 23 is 17 degree, and then estimate can be few 10% for the electric weight of battery, so the ratio value of electric weight and the electric weight that is full of electricity can be than being low when 30 spend after the adjustment when 17 spend.
Only for giving an example, so that the reader understands, its real figure can be provided by battery manufacturers for the above-mentioned charge value 241 and the numerical value of temperature value 242.And sensing element 23 be preferably a thermocouple, a thermistor and a temperature sensor one of them.See also shown in Figure 3ly, it is the embodiment flow chart of steps for the battery coulometric detection method of portable electronic devices of the present invention.According to the battery coulometric detection device of above-mentioned portable electronic devices, the present invention's battery coulometric detection method of more can deriving, in its steps flow chart, step 31 is to store a plurality of charge values and a plurality of temperature value, and each charge value is corresponding with a temperature value respectively.Follow the temperature arround step 32 is the sensing battery, and produce a temperature signal, then this temperature signal and stored temperature value are compared, when comparing, then read the charge value of corresponding temperature value with temperature value that temperature signal is consistent in step 33.Continue it, step 34 is according to this charge value the electric weight of battery to be adjusted, and is last, and step 35 shows that adjusted electric weight is on portable electronic devices.
In sum, can further adjust battery electric quantity, under the high environment of temperature, more can suitably improve the service time of battery, thus the actual total electric weight of reaction cell more accurately according to the temperature arround the sensing battery.
The above only is an illustrative, but not is restrictive.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the claim scope of the present invention its equivalent modifications of carrying out or change.
