The invention discloses a lithium battery electric bicycle conduction type safe and fast charger and a charging method. The lithium battery electric bicycle conduction type safe and fast charger comprises a current output adjustable switching power supply, a signal conditioning module, a microprocessor module, a DCDC converter, a temperature sensor array data collector, a voltage sampling circuit and an alarm module. The signal conditioning module is respectively connected with the current output adjustable switching power supply and the microprocessor module; and the temperature sensor array data collector is connected with the microprocessor module. In order to solve the problem of time lag of temperature diffusion and propagation, the temperature sensor array data collector is used, the temperature of the lithium battery of the electric vehicle can be found faster than a few temperature measuring points, charging energy supply can be stopped when the temperature does not reach an ignition point, and fire disasters are prevented. According to the invention, the intensity of the automatically adjusted constant-current charging current is automatically selected under the charging safety condition, so that the purpose of safe and fast charging is achieved.
