Whole vehicle thermal management system based on diesel oil range extending type electric light truck

Abstract

The invention relates to a whole vehicle thermal management system based on a diesel oil extended-range electric light truck. The system comprises an independent water path. The independent path comprises a low-temperature radiator, a four-in-one controller, an ISG controller, a second pressure-bearing kettle, a motor water pump, an ISG and a driving motor connected in sequence; a battery pack water path comprises a battery pack water pump, a water inlet temperature sensor, a battery pack, a heat exchanger and a third pressure-bearing kettle which are connected in sequence; an engine water path comprises a first pressure-bearing kettle, an engine, an intercooler and a high-temperature radiator; a heating water path comprises a warm air electronic water pump, a water PTC (Positive Temperature Coefficient) and a warm air core body which are connected in sequence; a cooling water path comprises a first cooling water path and a second cooling water path which are connected in parallel; wherein the engine water path, the heating water path and the battery pack water path are connected into a system water path through the electronic four-way valve and the electronic three-way valve; the water path is controlled through software according to the engine state, the cooling and heating requirements of a cab and the cooling and heating requirements of a battery pack.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle thermal management system based on a diesel extended-range electric light truck. Background technique [0002] Traditional fuel light trucks only involve engine thermal management, pure electric light trucks involve two thermal management channels, one is an independent waterway composed of drive motor, drive motor controller, DCDC, etc., and the other is a battery pack waterway, while extended-range electric light trucks involve drive Motor, drive motor controller, generator, generator controller, DCDC and other independent water circuits and engine thermal management, battery pack thermal management three-way thermal management water circuit, most of the current practice is to simply drive the motor, drive the motor controller , Generator, generator controller, DCDC, etc. are used as one thermal management channel, one thermal management channel for the engine, on...
