Learn about the fast charging method of 602030 lipo battery!
There are many ways to charge 602030 lipo battery. For the requirements of fast charging, the main methods include pulse charging, reflex charging, and smart charging. Different battery types have different applicable charging methods, so we will not make a specific distinction in this method section.
Pulse charging
Pulse charging mainly includes three stages: pre-charging, constant current charging, and pulse charging. During the constant current charging process, the battery is charged with a constant current, and part of the energy is transferred to the inside of the battery. When the battery voltage rises to the upper limit voltage (4.2V), it enters the pulse charging mode: the battery is charged intermittently with a pulse current of 1C. The battery voltage will continue to rise during the constant charging time Tc, and the voltage will slowly drop when charging stops. When the battery voltage drops to the upper limit voltage (4.2V), the battery is charged with the same current value to start the next charging cycle, and the charging cycle is repeated until the battery is fully charged. During the pulse charging process, the battery voltage will gradually slow down, and the charging stop time T0 will become longer. When the constant current charging duty cycle is as low as 5% to 10%, the battery is considered to be fully charged and charging is terminated. Compared with conventional charging methods, pulse charging can charge with a larger current. During the charging stop period, the concentration polarization and ohmic polarization of the battery will be eliminated, making the next round of charging smoother. The charging speed is fast, the temperature change is small, and the impact on the battery life is small. Therefore, it is widely used at present. But its disadvantages are obvious: a power supply with a current limiting function is required, which increases the cost of the pulse charging method.
Intermittent charging method
Lithium battery intermittent charging methods include variable current intermittent charging method and variable voltage intermittent charging method.
1) Variable current intermittent charging method
The variable current intermittent charging method was proposed by Professor Chen Tixian of Xiamen University. Its characteristic is that constant current charging is changed to voltage-limited variable current intermittent charging. As shown in the figure below, in the stage of the variable current intermittent charging method, a larger current value is first used to charge the battery, and charging is stopped when the battery voltage reaches the cut-off voltage V0. At this time, the battery voltage drops sharply. After a period of charging stop time, the charging is continued with a reduced charging current. When the battery voltage rises to the cut-off voltage V0 again, charging is stopped. After several reciprocating times (generally about 3 to 4 times), the charging current will be reduced by the set cut-off current value. Then enter the constant voltage charging stage, charge the battery at a constant voltage until the charging current decreases to the lower limit, and the charging ends.
In the main charging stage of the variable current intermittent charging method, the charging current is increased by an intermittent method with a gradually decreasing current under the condition of a limited charging voltage, that is, the charging process is accelerated and the charging time is shortened. However, this charging mode circuit is relatively complex and expensive, and is generally only considered for high-power fast charging.
2) Variable voltage intermittent charging
Based on the variable current intermittent charging method, some people have studied the variable voltage intermittent charging method. The difference between the two lies in the charging process of the stage, replacing the intermittent constant current with intermittent constant voltage. Comparing the above figure (a) and figure (b), it can be seen that constant voltage intermittent charging is more in line with the charging curve. In each constant voltage charging stage, due to the constant voltage, the charging current naturally decreases according to the exponential law, which is in line with the characteristic that the battery current acceptability rate gradually decreases as the charging progresses.
Reflex fast charging method
The Reflex fast charging method is also called the reflective charging method or the "hiccup" charging method. Each working cycle of this method includes three stages: forward charging, reverse instantaneous discharge and stop charging. It solves the battery polarization phenomenon to a great extent and speeds up the charging speed. However, reverse discharge will shorten the life of 602030 lipo battery.
In each charging cycle, a 2C current is first used for charging time Tc of 10s, then Tr1 with a charging stop time of 0.5s, Td with a reverse discharge time of 1s, and Tr2 with a charging stop time of 0.5s. Each charging cycle time is 12s. As the charging progresses, the charging current will gradually decrease.
Intelligent charging method
Intelligent charging is currently the most advanced charging method. Its main principle is to apply du/dt and di/dt control technology, judge the battery charging state by checking the increment of battery voltage and current, dynamically track the acceptable charging current of the battery, and make the charging current close to the acceptable charging curve of the battery from beginning to end. This type of intelligent method generally combines advanced algorithm technologies such as neural networks and fuzzy control to achieve automatic optimization of the system.
