Background

The hybrid electric vehicle (i.e. the hybrid electric vehicle) is provided with a power source by an engine and a power battery, and can realize pure fuel running, pure electric running and hybrid power running. Currently, most hybrid vehicles employ Power Split (PS) technology. The power distribution is carried out between the engine and the motor according to working conditions by the hybrid motor vehicle adopting the PS technology so as to ensure optimal dynamic property and economical efficiency.

In general, in order to alleviate the problems of battery cell damage and influence on battery life caused by charging a battery in a low-temperature environment, the charging of a power battery is limited in the low-temperature environment. For example, at 0 ℃, the charging power of the power cell is limited to below 3kW, while below-5 ℃ charging of the power cell is not permitted. Further, since the power split technique is employed, the engine has a charging power output at the time of starting, and therefore the power of the engine is limited at low temperatures. Based on the influence of the above factors, the thermal management of the hybrid vehicle in a low-temperature environment is very challenging.

In the related art, there are two kinds of thermal management schemes of hybrid vehicles in a low temperature environment as shown in fig. 1 and 2. In the first embodiment shown in fig. 1, in the cabin (or passenger cabin) independent heating mode, heat is supplied to the cabin through the engine 102 and the circuit (simply referred to as the first circuit) where the warm air core 104 is located; in the battery heating mode, the battery 110 is heated by the engine 102, the warm air water cut valve 111, the circuit in which the heat exchanging device 108 is located (short for circuit two), and the circuit in which the first water pump 109, the heat exchanging device 108, and the battery 110 are located (short for circuit three). In a second scheme shown in fig. 2, when the cockpit is heated solely and the power distribution mode is a fuel mode or a hybrid mode, the cockpit is heated by a circuit (referred to as a circuit four) where the engine 102, the first three-way valve 103, the warm air core 104 and the second three-way valve 105 are located; when the cockpit is heated singly and the power distribution mode is a pure electric mode, the cockpit is heated by a loop (short for a loop five) where the second water pump 106, the WPTC107, the heat exchange device 108, the first three-way valve 103, the warm air core 104 and the second three-way valve 105 are positioned; in the battery heating only mode, the battery 110 is heated by the circuit five, and the circuit (simply referred to as the circuit six) in which the first water pump 109, the heat exchange device 108, and the battery 110 are located. In fig. 1 and 2, the engine 102 is also cooled by the engine radiator 101.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.

The inventors of the present disclosure found that the scheme in the related art has the following two disadvantages. Firstly, only the waste heat of the engine can be used for heating the battery at low temperature, the heating time is long, and the heating efficiency is low. Specifically, in the cooling mode, when the battery cell temperature is less than-5 ℃, the battery cannot be charged. In order to avoid power split to charge the battery, the engine is always in an idle state, and the power of the engine is very low. This makes the temperature rise of the circulating water flowing through the engine particularly slow, which in turn results in a long time required for indirectly heating the battery pack with the circulating water. Experiments show that when the ambient temperature is-20 ℃, if the hybrid electric vehicle is kept stand for one night, more than 30 minutes are needed to wait after cold start, and the temperature of the battery core can be heated to a driving state.

Secondly, only the cockpit can be heated in the fuel mode, but the cockpit can not be heated in the pure electric mode, the cockpit heating mode is single, and the user experience is poor. Specifically, as shown in fig. 1, the thermal management system in the first embodiment has no electric heater, which means that there is no heat source in the pure mode, and the cabin cannot be heated in the pure mode. Thus, at low temperatures, the user cannot experience a purely electric driving experience.

The second scheme in the related art has the following two disadvantages. First, only an electric heater can be used for heating the battery at low temperature, waste heat of the engine cannot be utilized for heating the battery, and energy consumption is high. In addition, in the pure electric mode, only the electric heater can be used for heating the cockpit, and the waste heat of the engine cannot be used for heating the cockpit, so that the energy consumption is high. Specifically, as shown in fig. 2, the engine heating water circuit and the electric heater heating water circuit are two circuits connected in parallel. In the mixed mode, hot water flowing out of an engine water outlet pipe passes through a first three-way valve, flows through a warm air core body for heat exchange, and flows back to an engine recovery pipe through a port 1 and a port 2 of a second three-way valve after heat exchange, so that a circulating water pipeline is formed. In the pure mode, the electric heater heats water (e.g., antifreeze) and pumps the hot water out through the water pump. After flowing through the heat exchange device and the first three-way valve, hot water flows through the warm air core body to exchange heat, and after flowing through the port 1 and the port 3 of the second three-way valve, the hot water after heat exchange finally returns to the electric heater, so that a circulating water pipeline is formed. If the battery has a heating request at this time, the first water pump works, so that water flows through the heat exchange device to exchange heat, and then flows through the battery liquid heating plate to heat the battery. However, in the pure electric mode, the water in the engine heating water loop cannot be used for heating the cockpit, the cockpit can be heated only by starting the electric heater, the WPTC power consumption is large, and great energy waste is caused.

And secondly, the pipeline in the scheme II has a complex structure, high cost and high failure rate. Specifically, due to the adoption of the power split technology, when the vehicle running speed is in a low speed section, the hybrid mode and the pure mode are frequently switched. In this case, the failure rate increases due to the complex system principle, and the life of the relevant components is also affected. Particularly, the service lives of the first three-way valve and the second three-way valve can be greatly reduced due to the influence of different pressure differences of the two loops before and after switching.

In view of this, the present disclosure proposes a thermal management control method, apparatus, thermal management system, and vehicle for a hybrid vehicle, by designing a first heating pipe and a second heating pipe in parallel, and connecting an engine and an electric heater in series in the second heating pipe, thermal management control is performed based on the above structure, which is conducive to improving the thermal management effect, and can increase the life of the thermal management pipe.

In some embodiments, a second water pump 106 and a warm air core 104 are also provided on the second heating circuit. Wherein the engine 102, WPTC 107, second water pump 106, and warm air core 104 are connected in series.

In some embodiments, the hybrid vehicle thermal management circuit further includes an engine radiator 101 for dissipating heat from the engine 102.

In the embodiment of the disclosure, the first heating pipeline and the second heating pipeline which are connected in parallel are designed, and the engine and the electric heater are connected in series in the second heating pipeline, so that the engine, the electric heater or the combination of the engine and the electric heater can be flexibly selected for heating in different heat management modes, and the heat management effect is improved; moreover, the heat management pipeline is simple in design, valve structures such as a three-way valve and a four-way valve are not required to be arranged, and the service life of the heat management pipeline is prolonged.
