　　This method includes the second -stage charging method and the third -stage charging method

　　① The second phase method uses a fast charging method combined with constant current and constant voltage. First, charging the voltage value of the constant current to the predetermined voltage, and then the constant voltage is changed to complete the remaining charging. Generally, the conversion voltage between the two stages is the constant voltage of the second stage.

　　② The third -stage charging method uses constant current charging at the beginning and end of the charging, and charging with constant voltage in the middle.

　　When the current is attenuated to the predetermined value, it is converted from the second stage to the third stage. This method can reduce the amount of gas to the least, but as a fast charging method, it is limited by certain restrictions.

　　Fast charging method

　　① The pulse charging method, this charging method not only follows the inherent charging acceptance rate of batteries, but also improves the battery charging acceptance rate, thereby breaking the limit of the battery index charging accepted curve, which is also the new development of battery charging theory. The pulse charging method is first charged with the battery with pulse current, and then the battery stops for a period of time. This cycle is shown in Figure 5. The charging pulse is full of batteries, and the intermittent period causes the battery to redefine the oxygen and hydrogen generated by the chemical reaction of the battery to be redefined and absorbed, so that the thickness and ohmization of the thickness and ohmization are naturally eliminated, which reduces the internal pressure of the battery. The next round of constant current charging can be carried out more smoothly, so that the battery can absorb more power. The intermittent pulse has a sufficient response time for the battery, reducing the amount of gas analysis, and increasing the charging current acceptance rate of the battery.

　　② 2ReflextM fast charging method. This technology is a patented technology in the United States. It mainly faces the charging object is nickel -cadmium battery. Because it uses a new type of charging method to solve the memory effect of nickel -cadmium batteries, it greatly reduces the fast charging time of the battery. The charging method of the lead -acid battery and the detection method of the charging state is very different from that of the nickel -cadmium battery, but a working cycle of the REFLEXTM charging method can be borrowed from each other. Maintain 3 stages.

　　③ The current charging method is based on the basis of constant current charging and pulse charging, as shown in Figure 7. It is characterized by changing the constant current charging section to a limited voltage transformer intermittent charging section. Each section in the early stage of charging adopts a method of charging a variable -current intermittent charging to ensure increased charging current and obtain most of the charging volume. In the later period of charging, a fixed -voltage charging section was used, and the charging volume was obtained to restore the battery to a complete charging state. Through intermittently, the oxygen and hydrogen generated by the battery through chemical reactions have the time to redefine and absorb it, so that the thickness and ohmization are naturally eliminated, thereby reducing the internal pressure of the battery, so that the next round of round The constant current charging can be carried out more smoothly, so that the battery can absorb more power.

　　④ The transformer voltage intermittent charging method, on the basis of the transformer intermittent charging method, some people propose the transformer voltage intermittent charging method, as shown in Figure 8. Different from the variable current intermittent charging method is that the first stage is not intermittent constant current, but intermittent constant pressure. In each constant voltage charging phase, due to constant voltage charging, the charging current naturally decreases according to the index of the index, and the acceptance rate of the battery current is gradually declining with the charging rate.

　　⑤ Voltage Differential Disposal Intermittent Terminal and Negative Zero Pulse Quick Charging Method, the advantages of the convergence pulse charging method, RefleXTM fast charging method, transformer intermittent charging method and transformer intermittent charging method.
