The lithium battery of an electric vehicle and the lithium battery of a model airplane are not the same thing. The batteries are different, the chemical composition is different, and the maximum charge and discharge currents are different, so they cannot be compared. If the lithium battery of the airplane is charged in series, it is easy to overcurrent, and the characteristics of multiple batteries cannot be completely consistent. Series charging will cause the voltage of each battery to be unbalanced.

　　The lithium battery of an electric vehicle and the lithium battery of a model airplane are not the same thing. The batteries are different, the chemical composition is different, and the maximum charge and discharge currents are different, so they cannot be compared. If the RC lithium battery is charged in series, it is easy to over-current, and the characteristics of multiple batteries cannot be completely consistent. Series charging will cause the voltage of each battery cell to be unbalanced, or even fail to charge. The principle of balanced charging is very simple. For example, a 3S battery is composed of three 3.7V batteries in series. After fully charged, each battery is 4.2V, and the overall external connection is about 13V. Balanced charging transforms and rectifies the AC power to obtain 13V DC power. Three electrolytic capacitors and a voltage equalizing resistor divide the 13V voltage, and each capacitor gets 4.33V. Then use a triode to make a simple closed-loop circuit, which can control the charging switch and the current size, so that 3 cells can be Charged independently.webcam factory

　　The so-called equalization charging is the charging of equalizing the characteristics of the battery. It means that the battery terminal voltage is unbalanced due to the individual differences and temperature differences of the battery during the use of the battery. In order to avoid the deterioration of this imbalance trend, the battery needs to be improved. The charging voltage of the group activates the battery. The main reason is that the battery life is longer. The actual balance of the electric vehicle is to charge the rated voltage of 48v and the charging voltage is charged at 60v, and the last is floating charge.

　　The ESC is one of the main components of the electric model airplane. The working principle is to connect the battery to the receiver and the brushless motor. There are two main functions. One is to step down the battery to 5V, which is suitable for the working voltage of the receiver and other steering gears; the other is to obtain the throttle signal from the receiver to control the speed of the motor, thereby changing the speed of the aircraft. If you build your own methanol machine, it is best to use an ESC, because the ESC also has a function of stabilizing. No matter how the battery voltage changes, the output value of the ESC will always maintain a stable voltage of 5V (except for the high-voltage version), so that The receiver and steering gear work normally. If the battery is used directly, after the voltage is reduced, the receiver is prone to run out of control caused by insufficient voltage, which is more dangerous
