Charging supply Rectifier for battery charging. In the early days, an AC motor-DC generator set (also called a rotary unit) was used as a charging power source. After the 1960s, the charging power source composed of power electronic devices was replaced. Charging power often uses a single-phase (or three-phase) half-controlled rectifier circuit (composed of a thyristor and a diode, the load voltage cannot be reversed) or an uncontrolled rectifier circuit (composed of a rectifier diode without controlled kinetic energy) and an AC voltage regulator Rectifier circuit, in the DC circuit, it is necessary to use a smoothing reactor to suppress the DC current ripple and prevent the current from being discontinuous.
Battery charging methods are usually: ① constant voltage charging. The charging voltage is constant, and the charging current decreases as the battery voltage increases until it reaches zero. ② Constant current charging. In order to prevent air bubbles and acid mist, a constant current charging method that gradually decreases the current in stages is commonly used. ③ Constant voltage and constant current charging. Charge at a constant current first, and then charge at a constant voltage when the voltage reaches to generate bubbles. ④Charge out gas rate. First charge with a large current. When the battery discharge rate reaches a constant value, reduce the charging current to stabilize the discharge rate at a lower value. ⑤ Constant temperature charging method. After the battery temperature rises to a certain value, the charging current is reduced to keep the battery temperature at a specified value. In addition, pulse charging, discharging, and fast charging technologies appeared after the 1950s. It only takes tens of minutes to charge (tens of hours for regular charging). In addition to the charging circuit, the fast charging power supply also has a discharging circuit. In addition to the main circuit, all types of charging power supplies must have corresponding detection and control circuits.
