The invention discloses a multifunctional low-voltage distribution box for an electric vehicle. The multifunctional low-voltage distribution box comprises a vehicle control unit (VCU), wherein the vehicle control unit (VCU) is connected with a storage battery, a converter and a power distribution unit; the power distribution unit comprises a current detecting unit, an electromagnetic interference shielding unit and a control relay which are connected in sequence; the current detecting unit is further connected with the storage battery and the vehicle control unit (VCU) respectively; a power switch (K) is also connected between the current detecting unit and the electromagnetic interference shielding unit; the vehicle control unit (VCU) further comprises a voltage detecting unit connected with the vehicle control unit (VCU); the voltage detecting unit is connected with the positive electrode and the negative electrode of the storage battery. According to the distribution box, power supplies of high-power electric equipment and driving cab electric equipment are separated, overlarge circuit load or mutual interference of the electric equipment is reduced, the power supplies are better distributed, and the circuit protection is facilitated.
