The invention discloses a method for generating and controlling charging and discharging pulses of a pulse charging device. The invention belongs to a pulse charging technology based on a switch power supply. In order to innovate the conventional mode that a pulse voltage is rectified and filtered into a direct current voltage and the direct current voltage is then converted into a pulse in outputting of the charging pulse by adopting the pulse charging technology of a foreign special charging control integrated circuit, and to solve the problem that a switch transformer is adopted to output pulse charging and to generate the discharging pulse simultaneously, a method for adopting a secondary winding of the switch transformer to output the pulse charging and introduce outputting of the charging pulse to trigger a single steady-state circuit which is formed on the basis of a time-base circuit to convert into outputting of the discharge pulse which is alternated simultaneously with the charging pulse in a temporary steady state is provided, and the method for automatically regulating a control end voltage of the time-base circuit to control the discharge pulse and improving the conventional charging control circuit and a voltage stabilizing circuit to control the charging pulse is provided. The method provided by the invention is applied to charging of a lead acid battery, and charging effects on other batteries are required for further test.

Problems solved by technology

The present invention aims at innovating the existing charging mode including the use of foreign relatively advanced charging dedicated control integrated circuits or the pulse charging technology of single-chip microcomputers. The output pulses of the switching transformers must first be rectified and filtered into DC voltages and then converted into pulses, so as to solve this problem. The charging output circuit of the charging mode must be connected in series with power transistors, which leads to the problems of relatively complicated charging output circuit and relatively high manufacturing and maintenance costs; there is no solution to the existing technical solution of using the secondary winding of the switching transformer to output pulse rectification to charge the battery The technical problem of synchronous alternation of discharge pulses and charge pulses
