Problems solved by technology
[0008] However, for example, when the vehicle is in a drivable state, the high-voltage battery is in a charged state, and the temperature of the cooling water reaches a preset temperature, the driving conditions of the electric water pump of the cooling control device are limited
Therefore, since the electric water pump is not easily driven, air bubbles cannot be discharged to the degassing tank by circulating the cooling water
[0009] In the method of driving the electric water pump to discharge air bubbles, special tools or maintenance tools should be prepared, and complicated operations or lengthy work are also required
In addition, since the cooling water channel is usually installed in a curved state, only the electric water pump is driven to circulate the cooling water, and air bubbles may remain in the channel
[0010] Therefore, there is a problem of inconvenience due to the need for the occupant of the electric vehicle to request the vehicle manufacturer or the like to remove the air bubbles.

There is provided a cooling control apparatus for an electrically driven vehicle. A propulsion device comprising an electric motor which is configured to output a driving force for driving the electrically driven vehicle. A cooling device includes cooling water for cooling the propulsion device, and is connected to the propulsion device. A control device is configured to change the circulation rate of the flowing cooling water in the cooling device. The control device includes a cooling control unit, an operation detection unit and a bubble elimination control unit. The cooling control unit is configured to change the circulation rate of the cooling water in accordance with a temperature of the propulsion device. The operation detection unit is configured to detect a predetermined operationperformed by a user. The bubble elimination control unit is configured to control the cooling water to a circulation velocity that is higher than that set by the cooling control unit circulation rate when the predetermined operation is detected by the operation detection unit.
Description
technical field [0001] The present invention relates to an electric vehicle having a running device including an electric motor for driving the electric vehicle, and particularly to a cooling control device capable of cooling the running device. Background technique [0002] Recently, environmentally friendly electric vehicles, such as electric vehicles (EVs), hybrid electric vehicles (HEVs), or fuel cell vehicles (FCVs), have drawn attention. An electric vehicle has a traveling device including a driving motor. In addition to the electric motor, the running device also includes high-voltage devices such as generators, inverters for controlling electric motors, DCAC inverters for output accessory sockets AC100V, DCDC converters for supplying DC12V, high-voltage batteries, and high-voltage batteries charger. [0003] An electric vehicle includes: a cooling device containing cooling water for cooling (or heating) a running device including a high-voltage device and connected...
