Lithium-ion battery voltage power relationship, how to get electricity according to the lithium ion battery voltage? Lithium-ion batteries are a class of batteries that use non-aqueous electrolyte solutions using a lithium metal or lithium alloy, due to the processing, preservation, use, and environmental requirements of lithium metal. With the development of science and technology, now the lithium-ion battery has become mainstream. This article will give you a lithium-ion battery voltage power relationship and how to get power according to the lithium ion battery voltage? The characteristic of the lithium-ion battery voltage charge relationship between the lithium ion battery is measured when discharging, the lithium ion battery voltage will gradually decrease and have a relatively large slope, but in fact the voltage of the lithium ion battery is more than the water tank.
The calm water height measurement is more complicated. Estimated the residual capacity of the lithium ion battery with a voltage, the remaining capacity of the lithium ion battery has the following instability: When the same lithium ion battery is in the case of the same remaining capacity, the voltage value varies due to the magnitude of the discharge current. The larger the discharge current, the lower the voltage; the voltage is highest in the case of no current; 2 The effect of ambient temperature on the voltage of lithium ion battery: The lower the temperature, the lower the same capacity battery voltage; 3 cycles affect the effect of lithium ion battery discharge platform: The discharge platform for lithium-ion battery tends to deteriorate, and the discharge platform is lowered.
Therefore, the capacity represented by the same voltage is also correspondingly varied; the platform of different manufacturers and different capacity lithium-ion batteries is slightly different. How to get power based on lithium ion battery voltage? If the charge of all batteries, the size of the remaining electricity can be obtained, and when the lithium ion battery is charged well and is known to be completely charged, the use of current integral method is very good. This method is successfully applied to the current multi-battery power monitoring process.
A voltage-based method belongs to one of the earliest applications, it only needs to measure the voltage between the cells. Based on certain known relationships existing between the lithium ion battery voltage and the remaining electricity, the lithium ion battery voltage will distortion due to the pressure drop caused by the internal impedance of the lithium ion battery during application. In addition, even if the load is removed, the tension of the lithium ion battery will also cause the voltage to vary the voltage, the temperature, discharge rate, and battery aging during the actual charging process will affect the charging state.
How to accurately measure the remaining electricity quantity in the lithium ion battery: Voltage Test: Data obtained by simply monitor the voltage of the lithium ion battery, then display the amount of the lithium ion battery to the limit of the lithium ion battery, but the electricity and voltage of the lithium ion battery It is not a linear relationship of regularity, so the amount of electricity measurement is not high. 2, lithium-ion battery modeling method: establish a data table according to the discharge curve of the lithium ion battery, indicate the amount of electricity at different voltages, which can significantly increase the accuracy of the measurement. Mobile phone manufacturers have to go through a large number of tests to get this data, and the relationship between the voltage and power of the lithium-ion battery involves the temperature, self-discharge, aging of the lithium-ion battery, so this method is the most inconsistent.
3, Coulombia: One power metering chip is connected in series on the loop of the lithium ion battery, and the current is flowing through the circuit in the time of the resistance test unit. If the current is different, it has different differential pressure after different currents, and flows through different currents. By accumulating this changed current, calculate the amount of lithium ion battery.
The above is the method of voltage and electricity voltage of lithium ion battery and method for obtaining electricity according to the lithium ion battery voltage. If you continue to use under low power, the lithium-ion battery is easily damaged each time the low power tips is still not charged, and the lithium-ion battery is easily damaged, and the health will also fall quickly. So once we often use the loss, we will obviously feel shorter.
