g the power of lithium iron phosphate battery.convenient energy storage power supply Manufacturing

release time:2023-05-06 Hits: Popular:AG11 battery

(1) Voltage test method: simply monitor the battery voltage to obtain the power of lithium iron phosphate battery. The power and voltage of the battery are not linear, so the test method is not accurate, and the power measurement accuracy is only more than 20%. Especially when the battery power is lower than 50%, the power calculation of the mobile phone will become very inaccurate. Therefore, this method has very limited protection for the battery.

(2) Battery modeling method: This method is to establish a data table according to the discharge curve of lithium battery. The data sheet will show the power values at different voltages. This method can effectively improve the measurement accuracy. However, it is not easy to obtain accurate data sheets, because the relationship between voltage and current also involves such factors as battery temperature, self discharge and aging. Only by integrating various factors can we get more satisfactory results of electric energy measurement.

(3) Electricity meter: the electricity meter checks the resistance of lithium battery positive pole and negative pole string, such as current. VSENSE occurs when a current flows through the resistor. By detecting VSENSE, the current flowing through the battery can be calculated. It can be seen from the above three methods that the coulometer has the highest accuracy. Reduce the discharge cut-off voltage of the battery without damaging the lithium iron phosphate battery, so as to maximize the use of battery capacity, especially for low-voltage systems and batteries used for many times. In addition, it can more accurately send the warning message of low lithium ion battery power to prevent users from losing data during use.
