Abstract

The invention relates to an energy management system and an energy management method. In any braking time period, the vehicle can realize the purpose of recycling the energy generated by braking.

Description

Energy management method and energy management system of new energy vehicle
Technical Field
The invention relates to the field of automatic control of new energy vehicles, in particular to an energy management method and an energy management system of a new energy vehicle, which can recover energy generated in a braking process and even make the new energy vehicle unnecessary to be provided with a mechanical braking system.
Background
Generally, a vehicle achieves a braking function by a brake pad contracting a vehicle hub. For such a mechanical brake system, the brake performance of the vehicle is significantly reduced under the condition that foreign matters enter between the brake pad and the hub, and potential safety hazards exist during vehicle running. In addition, when a vehicle passes through a long-distance steep slope, the brake pad can be rapidly heated and deformed due to long-time friction, the braking performance of the vehicle is rapidly reduced, and in an extreme case, a mechanical braking system can be in a failure state. At this time, since the vehicle is on a steep slope, the vehicle is more likely to cause a serious runaway situation. For new energy vehicles such as PHEVs or HEVs, some companies have developed an overall vehicle energy management system that recovers energy generated during braking of the vehicle. As shown in fig. 1, in the vehicle energy management system, the wheel braking energy is converted from mechanical energy to electrical energy by the generator, and the electrical energy is fed back to the ESS battery device by the motor controller. However, for this kind of vehicle energy management system, the basic condition for recovering braking energy is that the SOC of the ESS battery does not reach 100% during vehicle braking, and there is still room for storing electric energy. If the SOC of the vehicle reaches 100% when the vehicle brakes, the system cannot achieve the purpose of recovering the braking energy.

Fig. 1-2 are schematic diagrams of an energy management system of a new energy vehicle according to a preferred embodiment of the present invention.
Detailed Description
The concept of the present invention will be described in detail with reference to the accompanying drawings. What has been described herein is merely a preferred embodiment in accordance with the present invention and other ways of practicing the invention will occur to those skilled in the art and are within the scope of the invention.
Fig. 1-2 show an energy management system of a new energy vehicle in accordance with a preferred embodiment of the present invention, wherein fig. 1 shows the flow directions of electric power, coolant, and energy in a driving running state of the vehicle; fig. 2 shows the flow direction of the charge, the coolant and the energy in the braking state (braking state) of the vehicle. In the illustrated drawings, the new energy vehicle is a PHEV (plug-in hybrid vehicle) or an HEV (hybrid electric vehicle).
Referring to fig. 1, the energy management system according to the present invention comprises a micro control unit 1(MCU), a drive motor 2 and an energy storage unit 3(ESS), such as a battery 8. The micro control unit 1 is used as a central system and collects data of each monitored object and user instructions to control the action of each execution component.
The drive machine 2 shown in fig. 1 is a reversible machine, i.e. it can be used as a generator as well as a motor. One end of the drive shaft of the drive motor 2 is connected to the engine 4 and driven by the engine 4 to operate, and the other end of the drive shaft of the drive motor 2 is preferably connected to wheels 6 through a transmission 5 shown in fig. 1. Alternatively, a not-shown speed change mechanism may be provided between the engine 4 and the drive motor 2.
The drive motor 2 is furthermore connected to an energy storage unit 3, wherein the energy storage unit 3 as a power source is a high-voltage power battery. The driving motor 2 may drive the vehicle forward or backward by using power supplied from the engine 4 or electric power supplied from the energy storage unit 3, as an option. When the engine 4 drives the driving motor 2 to work, the driving motor 2 can drive the transmission 5 to work and further drive the wheels 6, and on the other hand, the driving motor 2 can generate electricity and transmit electric energy to the energy storage unit 3.
The high-voltage power battery is connected with the DC-DC conversion device 7 as a power source besides the driving motor 2. The high voltage is converted into low voltage by the DC-DC conversion device 7 and then stored in the low voltage storage battery 8, and then the low voltage storage battery 8 supplies power to a thermal management system in the vehicle; the low voltage power may optionally be stored in part in the low voltage battery 8, in part directly powering the thermal management system, or in part used entirely as a power source for the thermal management system at a time or during a period of time.
The thermal management system may include the heat sink 9, water pump 11, fan 10, etc. shown in fig. 1. The radiator 9, the fan 10 and the water pump 11 may be components of an air conditioning system in the vehicle on the one hand, and may be used as components of a heat exchange system of the engine 4, a shafting system and other mechanisms on the other hand.
According to the invention, the energy storage unit 3 is provided with a reserved braking energy recovery buffer zone to realize real-time recovery of energy generated in the vehicle braking process. The braking energy recovery buffer zone can be set by the micro control unit 1, and the electric energy capacity Q of the braking energy recovery buffer zone2The braking energy control device can be properly adjusted at any time according to the vehicle weight, the vehicle wind resistance, the average value of the braking energy generated by the specified mileage of the vehicle and the like. Specifically, the electric energy capacity Q2It is preferably set to satisfy the following condition: q is more than 02≤Q1X 5%, wherein Q1Is the total capacity of the energy storage unit 3. More preferably, the electric energy capacity Q2Is set to Q1×1％。
According to the above, since the braking energy recovery buffer area is provided, when the driver brakes the vehicle at any time, the micro control unit 1 can control the driving motor 2, so that the driving motor 2 is used as a motor, the braking energy generated in the braking process of the vehicle is converted into electric energy, and the electric energy is recovered to the braking energy recovery buffer area. The resistant torque produced by the drive motor 2 in this process is sufficient to brake the vehicle, so that the vehicle according to the invention can even eliminate the conventional mechanical band-type braking system.
The reserved braking energy recovery buffer zone can be preset and maintained in a plurality of ways of consuming the energy stored in the energy storage unit 3 in the vehicle braking process. Electric energy capacity Q of following buffer zone is recovered with braking energy2Is set to Q1The method for presetting and maintaining the reserved braking energy recovery buffer area is explained by taking x 1% as an example, and it can be understood that the electric energy capacity Q2Is set to be such as Q1×2％、Q1×3％、Q1X 4% or Q1X 5% or more of Q1The manner in which the braking energy recovery buffer is preset and maintained at x 5% has the same principle as in this example.
When electric energy capacity Q2Is set to Q1X 1%, when the vehicle is started, if the system monitors that the electric quantity Q of the energy storage unit 3 exceeds 99% x Q1The micro-processing unit or row of the energy management system transfers part of the energy storage unit 3 to the thermal management system with energy consuming components such as a fan 10, a water pump 11, etc. by means of, for example, heat, until the amount of electricity Q is less than 99% x Q1Therefore, a braking energy recovery buffer zone can be preset; and in the running process, if the system monitors that the electric quantity Q of the energy storage unit 3 reaches 99% multiplied by Q1The microprocessor unit of the energy management system starts to automatically distribute the energy stored in the energy storage unit 3 to energy consuming elements such as the fan 10 and the water pump 11, thereby avoiding the situation that the braking energy recovery buffer zone disappears due to the fact that the power battery is charged by the engine during the running process of the hybrid vehicle. In order to continuously maintain the braking energy recovery buffer to recover the braking energy during the braking process, the vehicle according to the invention also continuously consumes energy during the braking process. In an energy consumption mode, when the driver brakes the vehicle, the energy storage unit 3 outputs electric energy to the outside while receiving energy generated by the drive motor 2. The output electric energy can be transmitted to energy consumption elements such as a fan 10, a water pump 11 and the like through the DC-DC conversion device 7, so that the thermal management system works. In the process, according to the real-time monitoring of the electric energy storage situation of the energy storage unit 3If the electric energy of the energy storage unit 3 does not exceed the predetermined value, that is, the energy received by the energy storage unit 3 and the energy output by the energy storage unit are approximately in a dynamic balance state, the energy management system does not need to perform other actions; if the predetermined value is exceeded, the surplus energy can be stored to the accumulator 8 by the DC-DC conversion device, thereby avoiding the energy storage unit 3 from being rapidly charged with electrical energy without any more brake energy recovery buffer. It will be appreciated that in the above process, the battery 8 may now supply power to the various low voltage energy consuming components within the vehicle, thereby increasing the ability of the energy management system to recover braking energy. Wherein, preferably, the predetermined value can be set to Q2-Q2X 50% interval (containing Q)2And Q2X 50%) of the total amount of the organic compounds.
In another energy consumption mode, when the driver brakes the vehicle, on the one hand the micro control unit 1 controls the drive motor 2 to generate electricity; on the other hand, the micro control unit 1 controls the flow rate, temperature, etc. of the coolant for cooling the drive motor 2 so that the braking energy generated by the braking process of the vehicle is converted into the coolant in the form of heat energy. The coolant flowing out from the drive motor 2 is supplied to the radiator 9 via the water pump 11, and is used as a heat exchange medium for an air conditioning system or a cooling system to adjust the temperature of another heat exchange medium in the above system and achieve a temperature regulation effect.
When used as a coolant for the pump 11, the fan 10, the temperature of the coolant flowing out by the drive motor 2 is preferably set to be lower than 80 ℃.
In the above-described aspect, the temperature of the coolant may be adjusted by adjusting any one or more of an inflow temperature and an outflow temperature of the coolant, a temperature difference between the coolant before and after entering and exiting the drive motor 2, a flow rate of the coolant in the drive motor 2, and the like.
The micro control unit 1 may adjust the flow rate, temperature, etc. of the coolant at the time of braking of the vehicle, or may adjust the temperature at other time intervals. Preferably, the coolant temperature is not adjusted in the early stage of braking, thereby more using the braking energy as the power required for the running process of the vehicle. For example, in one embodiment, the energy storage unit 3 is provided with a threshold value T, and the micro control unit 1 controls to start adjusting the flow rate and temperature of the cooling liquid of the drive motor 2 only when the stored charge q of the energy storage unit is greater than the threshold value T.
Preferably, the threshold T satisfies the following condition: q1-70％×Q2≤T≤Q1-30％×Q2Wherein Q is1Is the total capacity, Q, of the energy storage unit 32And recovering the electric energy capacity of the buffer area for the braking energy. More preferably, the threshold T may be set to 50% × Q2。
When the microcontroller unit 1 distributes the energy generated during the braking process of the vehicle, the generated energy is preferentially used for driving the electric machine 2 and generating electric energy. In another mode of operation, as described above, the micro-control unit 1 distributes the stored energy q of the energy storage unit 3 so that the portion of the stored electrical energy used to activate the thermal management system is larger than the portion used to heat the thermal management system.
The scope of the invention is limited only by the claims. Persons skilled in the art, having benefit of the teachings of this disclosure, will readily appreciate that alternative constructions of the disclosed construction can be devised which do not depart from the scope of the invention as disclosed herein, and that such disclosed constructions can be combined to yield new embodiments which also fall within the scope of the appended claims.
