Continue the software view of various embodiments of the present invention to realize and describing below.
For the state processing that does not connect equipment, the core of this equipment is voltameter IC, after this device power-up, if in 30 seconds without any equipment access, directly shutdown enters sleep state.
Processing during for access discharge equipment state, when without any equipment access, only shows capacity and the percentage of battery.In the time starting to discharge, discharging current output detected, start the demonstration of discharging current voltage.
Processing during for access charging device state, in the time starting to charge, when charging voltage input detected, just starts to show discharging current.
For the processing that shows voltage, for example, adopt the collection of S27XX IC as electric current, voltage, battery capacity, wherein the principle of current acquisition is: S27XX measures pin V every 440ms
iNand V
sSbetween voltage, scope is 0 to 4.99V, resolution is 4.88mV.Voltage register adopts complement of two's two's complement form, upgrades once every 440ms, and voltage during higher than maximum register value, is reported maximum.Voltage is during lower than minimum register value, report minimum value.For example, adopt the collection of the IC such as the independent used voltameter IC of dallas semiconductor (DallasSemiconductor) DS2781, DS2784 as electric current, voltage, battery capacity.Or, adopt the MAX17040IC of U.S. letter as the collection of electric current, voltage, battery capacity.
Wherein, voltage register form is as shown in the table.
For the processing that shows electric current, S27XX IC is by measuring low resistance current sense resistor R
sNSthe pressure drop at two ends continues to detect the electric current that flows into and flow out battery.SNS and V
sbetween reference voltage detection be ± 51.2mV.As long as be no more than ± 51.2mV of persistent signal level, be i.e. no more than ± 51.2mV of mean value in the whole change-over period, the peak signal amplitude that input can linear transformation is up to 102.4mV.ADC carries out difference sampling with 18.6kHz speed to input, and in the time that each change-over period finishes, upgrades electric current register, and for example each change-over period is 3.52s.Represent with maximum 7FFFh higher than the peaked charging current of register, represent with minimum value 8000h lower than the discharging current of register minimum value.
Wherein, electric current register format is as shown in the table.
Average current register provides the average current value in front 28s.Register value adopts complement of two's two's complement form, upgrades interval 28s, and it is the mean value of 8 renewal values before electric current register.Specific code and voltage are processed similar, do not repeat at this.
For showing the processing of electric weight, in the time that the change-over period finishes each time, current measurement value sue for peace or accumulative total in sheet, and accumulated result is stored in totally in electric current register (ACR).Base precision when the precision of ACR depends on current measurement precision and conversion.The scope of ACR is 0 to 409.6mVh, and resolution is 6.25 μ Vh.Adjunct register has retained the fractional part of each accumulated result, to eliminate truncated error.The fractional part user of result can not access.When the accumulated value of charging current exceedes maximum register value, report maximum register value; When discharging current accumulated value is lower than minimum register value on the contrary, report minimum register value.
Charging current lower than 100 μ V does not add up, and does not add up lower than the positive electric current register value of 100 μ V, to eliminate the impact that accumulative total was caused of long-time little offset error.Here the minimum charging current of restriction, for coulomb counting, R
sNSwhen=0.020 Ω, be 5mA, R
sNSwhen=0.005 Ω, be 20mA.
Can also carry out read/write operation to ACR.While writing ACR, must first write MSB, and then write LSB.No matter when write ACR, all will remove the fractional part of accumulated result.Wherein, write operation must complete within an ACR register update cycle; For example, an ACR register update cycle is 3.5s.While writing ACR at every turn, will force ADC to carry out mistuning calibration function and change and upgrade dysbiosis calibration factor.In the time of the conversion for the second time of writing after ACR, start current measurement and accumulative total.
When power down, ACR value is backed up in EEPROM.While powering on, from EEPROM, recover ACR value.
Wherein, cumulative electric current register format is as shown in the table.
Units：6.25μVh/R
SNS
For lumen degree Graphics Processing, lumen degree, according to the voltage and current of solar cell, draws after MCU comparator is processed.Wherein the processing mode of battery capacity percentage etc. is the same with processing mode above, repeats no more here.
