THE EXPERIMENTAL RESEARCH OF PULSE CHARGER MODES

Abstract

Pulse intelligent chargers are widely used in technology. There are quite a few of them on the market. Transformer charging is gradually disappearing. They are outdated and dangerous. Requires constant monitoring during operation and adjustment. The intelligent charger uses a built-in microprocessor. It independently restores the electric charge of the battery, diagnoses, and selects the necessary operating parameters. Many scientists are concerned with the development of improved devices for charging with increased efficiency. The authors of the article reviewed the most common models of intelligent pulse chargers in a certain price range. The most universal was chosen based on the analysis of technical characteristics. This is the Foxsur FBC122410E model. For the selected Foxsur FBC122410E charger, experimental studies were conducted to study operating modes for accumulator batteries of different capacities. A multimeter and an oscilloscope were used. In CAR mode (battery 60 A·h): the maximum value of the charging current is not 10 A, but only 7 A; at the beginning of the cycle after testing, the desulfation mode begins; half-current charging; charging with the main maximum current; mode of decreasing current and increasing voltage; testing; storage. In MOTO mode (battery 7.2 A·h): the maximum value of the charging current is not 1.7 A, but only 1.5 A; there is no desulfation mode; after testing, charging with the main maximum current begins; the mode of absorption or reduction of the current strength at a constant value of the voltage; testing; storage. In the REPAIR mode, a pulsed current works that decreases with time. Its value is determined by the device based on the analysis of the battery.
