The invention provides an intelligent charger having a function of power failure detection. The intelligent charger includes an EMC / EMI rectifier filtering unit, a DC / DC conversion unit, an output end rectifier filtering unit and an MOS transistor control unit which are connected sequentially from an input end to an output end; and a switch tube connected with the DC / DC conversion unit, a PWM control unit connected with the switch tube and a voltage and current voltage stabilization feedback unit connected with the PWM control unit. The voltage and current voltage stabilization feedback unit is connected with an output end of the DC / DC conversion unit and a negative output end of a charger to acquire voltage and current. The intelligent charger further includes a single-chip microcomputer and a charging circuit detection unit. The charging circuit detection unit can achieve the function of measuring the battery voltage without a 220V input power supply. According to the invention, the combination of the intelligent charger and an electricity measurer function is achieved, an electricity measurer in a pure sense is no longer needed, the use is facilitated for users, and one machine with multiple functions is realized.
Description
technical field [0001] The invention relates to the field of chargers, in particular to an intelligent charger with a power-down detection function. Background technique [0002] Rechargeable batteries have the characteristics of high cost performance, large discharge current, and long life, and are widely used in various communication equipment, instruments, and electrical measuring devices. Different types of batteries should adopt different charging control technologies. Commonly used control technologies include: voltage negative increment control, time control, temperature control, maximum voltage control technology, etc., corresponding to various existing intelligent charging technologies. charger. However, the existing smart charger cannot accurately measure the residual power of the battery without inputting 220V voltage, so that it cannot accurately select the corresponding charging mode. Contents of the invention [0003] The technical problem to be solved by t...
