Abstract The present invention discloses a high-power intelligent charging machine and its charging method. Said charging machine includes controllable rectification circuit and control unit, also includes monitoring circuit, D/A conversion circuit, A/D conversion circuit and trigger circuit. Said invention adopts a current variable charging method, according to the detected quantity of electricity in the accumulator, initially it uses heavy-current to charge, then progressively reduces current until the charged electric quantity is enough, the current can be reduced to zero, so that the charging operation can be automatically implemented according to predefined charging curve. Besides, said invented charging machine is intelligent, can greatly prolong life of accumulator, shorten charging time and can save energy.
