Work vehicle
A work vehicle includes a battery that outputs a DC power, at least two electric motors, and at least two inverters, each inverter being configured to convert the DC power from the battery into an AC power and to supply the AC power to one of the electric motors. The work vehicle further includes an accommodation box attachable/detachable to/from the vehicle body, the accommodation box accommodating a plurality of electrical equipments including the inverters.
1. A work vehicle comprising:
a vehicle body;
a battery that outputs a direct current (DC) power;
at least two electric motors;
at least two inverters, each of the inverters being configured to convert the DC power from the battery into an alternate current (AC) power and to supply the AC power to one of the electric motors associated therewith;
an electronic control unit for controlling operation of the at least two electric motors; and
an accommodation box attachable/detachable to/from the vehicle body, the accommodation box accommodating a plurality of electrical equipment including the inverters,
wherein the electronic control unit is located outside of the accommodation box.
2. The work vehicle of claim 1 , further comprising:
a right traveling device and a left traveling device that support the vehicle body;
wherein the electric motors include at least one right traveling motor for driving the right traveling device and at least one left traveling motor for driving the left traveling device; and
the inverters include at least two traveling inverters for supplying the AC power to one of the traveling motors associated therewith.
3. The work vehicle of claim 1 , further comprising:
a right traveling device and a left traveling device that support the vehicle body;
an implement device configured to be detachably connected to the vehicle body;
wherein the electric motors include at least one right traveling motor for driving the right traveling device, at least one left traveling motor for driving the left traveling device, and at least one implement motor for driving the implement device;
the inverters include a traveling inverter for supplying the AC power to one of the traveling motors associated therewith, and an implement inverter for supplying the AC power to the implement motor.
4. The work vehicle of claim 1 , wherein the accommodation box is disposed adjacent to the battery and the electric motors.
5. The work vehicle of claim 1 , wherein:
the accommodation box includes a wall-face forming member that supports the inverters; and
the wall-face forming member functions as a heat sink.
