Inverter for driving motor of vehicle
An inverter for driving a motor of a vehicle mediating between a battery and a driving motor is disclosed. The inverter includes a power storage module, a power module, and a cooling module. The power storage module is configured to be supplied with power from the battery. The power module is configured to be supplied with power from the power storage module to transfer the power to the driving motor. The cooling module is configured to be installed between the power storage module and the power module to simultaneously cool the power storage module and the power module.
1. An inverter for driving a motor of a vehicle mediating between a battery and a driving motor, comprising:
a power storage module configured to be supplied with power from the battery;
a power module configured to be supplied with power from the power storage module to transfer the power to the driving motor;
a cooling module configured to be installed between the power storage module and the power module to simultaneously cool the power storage module and the power module: and
a connection module configured to connect the power storage module and the power module to transfer power;
wherein the connection module includes a plus plate connecting a plus terminal of the power storage module and a plus terminal of the power module and a minus plate connecting a minus terminal of the power storage module and a minus terminal of the power module;
wherein the plus plate and the minus plate are stacked with each other in an insulated state;
wherein each of the plus plate and the minus plate includes a first surface and a second surface;
wherein the first surface of each of the plus plate and the minus plate is inserted between the power storage module and the cooling module, and the second surface of each of the plus plate and the minus plate extends along a side surface of the cooling module from one end of the first surface of each of the plus plate and the minus plate;
wherein the first surface of the plus plate is stacked with the first surface of the minus plate, and the second surface of the plus plate is stacked with the second surface of the minus plate;
wherein the plus plate and the minus plate are stacked with each other in a shape of a single plate that is bent vertically at least once: and
wherein an entire lower surface of the cooling module contacts an entire upper surface of the plus plate, and an entire upper surface of the power storage module contacts an entire upper surface of the minus plate.
2. The inverter of claim 1 , wherein the plus plate and the minus plate are each formed in the shape of the letter L.
3. The inverter of claim 2 , wherein the connection module further includes a plus terminal extending from a second surface of the plus plate to be connected to a plus terminal of the power module and a minus terminal extending from a second surface of the minus plate to be connected to a minus terminal of the power module.
4. The inverter of claim 2 , wherein the first surface of the minus plate is provided with a through hole so that the first surface of the plus plate and the plus terminal of the power storage module contact each other.
5. The inverter of claim 2 , wherein the first surface of the plus plate is provided with a through hole so that the first surface of the minus plate and the minus terminal of the power storage module contact each other.
6. The inverter of claim 1 , wherein the cooling module cools the connection module, and the power storage module is indirectly cooled by the connection module.
