摘要： PURPOSE:To prevent application of a voltage or an allowable voltage or more to various units and to prevent damage of the units by so controlling a regeneratively braking amount that voltage and charging current of a battery become predetermined voltage and current values or less at the time of the regeneratively braking a motor. CONSTITUTION:The motor controller for an electric vehicle comprises current detecting means 10 to detect a charging current flowing to a battery 4, and auxiliary control means 8 of the controller 3 to control the current. Further, the controller comprises voltage detecting means 7 installed to detect a voltage of the battery 4 and to output a detected voltage value to the means 8 of the controller 3. In the case where the battery 4 is fully charged, when a motor 1 is relatively largely regeneratively braked, the voltage of the battery 4 becomes higher than a predetermined voltage value. In this case, the means 8 of the controller 3 monitors the voltage of the battery 4, controls the regeneratively braking amount of the motor 1, and prevents the voltage of the battery 4 from becoming the allowable value or more. Thus, damage of various units, deterioration and damage of the battery are prevented.
