The present invention discloses a liquid-cooled integrative power system for electric forklift and a forklift, including an integrated transmission gearbox, an integrated motor controller, a drive motor, an oil pump motor, an oil pump and a vehicle controller. The integrated transmission gearbox includes a drive motor transmission mechanism and an oil pump motor transmission mechanism. The integrated motor controller includes a drive motor control unit and an oil pump motor control unit. The integrated transmission gearbox, the integrated motor controller, the drive motor, the oil pump motor, the oil pump and the vehicle controller are completely integrated and mounted to form the liquid-cooled integrative power system for electric forklift. The liquid-cooled integrative power system for electric forklift according to the present invention has high integration and a small exterior envelope size, which cancels a connection between an external three-phase power harness and a low-voltage sampling control harness between the motor and the motor controller, thereby greatly improving safety of an electrical system and reducing power transmission losses and production costs.
