Description

Technical Field

[0001] The present invention relates to the field of electric energy for electric battery vehicles, and in particular to a green, low-carbon and sustainable electric energy conversion device for electric battery vehicles. Background Art

[0002] The electric vehicle electric energy to mechanical energy conversion device is an energy management system for electric vehicles. Its main function is to realize the two-way conversion between electrical energy and mechanical energy. It converts electrical energy into mechanical energy to drive the vehicle when the vehicle is running. At the same time, when the vehicle decelerates or brakes, part of the mechanical energy is recovered as electrical energy and stored in the battery, thereby improving energy utilization efficiency and extending the cruising range.

[0003] However, when recovering mechanical energy during vehicle deceleration or braking, the recovered mechanical energy needs to be converted into electrical energy and stored in the battery. However, during the storage or operation of the electric vehicle, the battery is stored inside the electric vehicle. In hot weather, if the electric vehicle is exposed to direct sunlight, the temperature of the battery storage location will rise sharply in a short period of time, making the battery environment unsuitable. At this time, if the recovered electrical energy is stored in the battery, it will accelerate the damage to the battery. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a green, low-carbon energy and sustainable battery vehicle electric energy conversion device.

[0005] The present invention provides a green, low-carbon and sustainable electric energy conversion device for a battery vehicle, comprising a power supply box, a generator, wheels and a motor, wherein the power supply box supplies power to the motor to drive the wheels to rotate, and when the throttle of the battery vehicle is released, the motor stops driving, and at this time, the rotation of the wheel drives the generator to rotate through a transmission system to perform power conversion and generate electricity, and the power supply box stores the electric energy converted by a rectifier, and further comprises:

[0006] The power supply box includes two battery packs;

[0007] A control unit, the control unit is used to control the generator to switch to the connected battery pack when the internal power of one of the battery packs exceeds 80%, control the generator to stop generating electricity when the internal power of two battery packs exceeds 100%, and control the generator to switch to the connected battery pack for electric energy storage when the internal power of one of the battery packs is less than 20%;

[0008] An environment adjustment component is installed on the power box and is used to adjust the inside of the power box to a suitable power conversion environment. The control unit is also used to control the generator to stop generating electricity when the environment of the power box is not suitable.

[0009] A wind energy supplement component is installed on the power box and is used to convert wind energy into electrical energy for storage during the movement of the battery vehicle;

[0010] During the driving of the electric vehicle, the battery pack inside the power box provides electric energy to the motor, so that the motor converts the electric energy into mechanical energy to drive the wheels to rotate, thereby driving the electric vehicle to drive through the rotation of the wheels. When the driver releases the accelerator of the electric vehicle, the control unit detects that the accelerator is released. At this time, the control unit controls the generator and the transmission system to connect the wheels, so that the rotation of the wheels drives the generator to rotate through the transmission system. After the generator rotates, it converts the mechanical energy into electric energy, and after conversion by the rectifier, the electric energy is stored in the battery pack, so that when braking or decelerating, the rotation of the wheels drives the electric energy recovery;

[0011] By setting two battery packs, when electric energy is recovered, if the power of one of the battery packs is ≥ 80%, the control unit detects the power of the battery pack, thereby controlling the generator to switch to connect to the other battery pack, thereby avoiding continuous charging of the battery pack when the power of the battery pack exceeds 80%;

[0012] When the control unit detects that the power of one of the battery packs is ≤20%, the generator is controlled to switch to connect to the battery pack, which is helpful to avoid the situation where the battery pack is damaged due to the power of the battery pack being less than 20%. In summary, through the adjustment of the control unit, the power of the battery pack tends to be maintained between 20% and 80%, which is helpful to extend the service life of the battery and avoid the situation where the battery pack is quickly damaged during the process of recycling electric energy;

[0013] When the control unit detects that the power of the two battery packs is ≥ 80%, the generator connects to the two battery packs in turn for charging. If the power of the two battery packs is fully charged, the control unit controls the generator to stop kinetic energy recovery, thereby helping to avoid overcharging damage to the battery packs;

[0014] The control unit is also used to control the two battery packs of the machine, one for kinetic energy recovery charging and the other for discharging to drive the wheels to rotate, so as to avoid frequent charging and discharging of the same battery pack, which may cause damage to the battery pack;

[0015] The environment adjustment component is set to adjust the internal environment of the power box to a suitable environment, so that the battery pack inside the power box can be charged and discharged in a suitable environment, which is helpful to avoid the battery pack being damaged due to an unsuitable environment during the charging and discharging process;

[0016] The wind energy supplement component can convert wind energy into electrical energy, thereby improving the power conversion efficiency of the battery vehicle, which is beneficial to enhancing the power of the battery vehicle when the battery vehicle is short of power, and is beneficial to improving the battery vehicle's endurance;

[0017] In summary, by controlling the charge and discharge of the battery pack and the charge and discharge environment, the battery pack can be charged and discharged in a suitable environment and state to reduce the damage caused by the battery in the continuous power conversion process and extend the service life of the battery pack.

[0018] Preferably, the wind energy supplement component comprises:

[0019] An air inlet, the opening of which faces the front of the battery vehicle;

[0020] A wind-driven chamber connected to the air inlet through an air inlet pipe;

[0021] The fan blades are rotatably mounted inside the wind-driven bin;

[0022] A wind-driven gear is coaxially fixed to the bottom of the rotating shaft of the fan blade;

[0023] A synchronous wheel, which rotates synchronously with the rotating shaft of the generator through a first rotating sleeve, and the synchronous wheel and the wind driving gear are synchronously driven through a synchronous belt;

[0024] When the battery vehicle is running, the airflow impacts the battery vehicle, so that the airflow enters from the air inlet under the action of wind force, and then enters the interior of the wind-driven compartment along the air inlet pipe.

[0025] When entering, the cross-sectional area of ​​the air inlet is large, while the cross-sectional area of ​​the air inlet pipe is small, so that the wind speed of the air flow is accelerated when passing through the air inlet pipe, so that when the air flow passes through the connection point of the air inlet pipe and the wind driven warehouse and enters the interior of the wind driven warehouse, the driving force of the fan blades inside the wind driven warehouse is increased, thereby driving the fan blades to rotate, and then the air flow is discharged from the bottom of the wind driven warehouse. After the fan blades rotate, they drive the wind-driven gear connected to them to rotate, and the wind-driven gear drives the synchronous wheel to rotate through the transmission of the synchronous belt. After the synchronous wheel rotates, it drives the first rotating sleeve to rotate, thereby driving the rotating shaft of the generator to rotate to generate electricity, thereby realizing auxiliary power generation through the action of wind force, which is beneficial to the recovery of the kinetic energy of the wheels of the electric vehicle when the kinetic energy of the electric vehicle is insufficient. The wind force generated by the relative action during the movement of the electric vehicle can be used for wind energy recovery, which is beneficial to improve the endurance of the electric vehicle.

[0026] Preferably, the environmental adjustment component comprises:

[0027] An inner box body is fixed inside the power box, and a vacuum layer is formed between the inner box body and the inner wall of the power box;

[0028] The setting of the inner box body forms a vacuum layer between the inner box body and the inner wall of the power box. The heat conduction efficiency inside the vacuum layer is poor, which helps to slow down the conduction speed of the external high or low temperature to the inside of the inner box body. This helps to avoid the external high or low temperature from quickly interfering with the inside of the inner box body when the electric vehicle is placed in the external environment, making the working environment of the battery pack inside the inner box unsuitable, thereby affecting the service life of the battery pack.

[0029] Preferably, the environmental adjustment component further comprises:

[0030] An air inlet is opened through the top of the power box, the bottom of the air inlet is connected to the inside of the inner box, and the top of the air inlet is fixedly connected to the bottom of the wind-driven compartment;

[0031] A first solenoid valve, fixedly installed inside the air inlet;

[0032] An exhaust port is provided through the bottom of the power box, and the top of the exhaust port is connected to the interior of the inner box;

[0033] A second solenoid valve is fixedly installed inside the exhaust port;

[0034] The air inlet is connected to the bottom of the wind-driven compartment, so that the airflow discharged from the bottom of the wind-driven compartment passes through the air inlet into the interior of the inner box, and then the airflow passes through the entire inner box and is discharged from the air outlet;

[0035] In the hot summer, when the battery car is not started, the first solenoid valve and the second solenoid valve are in a closed state, so that the interior of the inner box body will not generate airflow exchange with the outside, thereby reducing heat exchange. When the battery car starts to move, the first solenoid valve and the second solenoid valve are opened. Since the battery car generates airflow relative to the air when it moves, in the summer temperature, when the flowing airflow passes through the interior of the inner box body, it will not cause the temperature around the battery pack inside the inner box body to exceed the appropriate temperature, and it will also drive the airflow to flow, thereby driving the temperature generated by the battery pack when it is working to be discharged, which is beneficial to heat dissipation around the battery pack, thereby helping to keep the battery pack in a suitable temperature environment for charging and discharging, thereby helping to extend the service life of the battery pack;

[0036] In cold winter, the first solenoid valve and the second solenoid valve are in a closed state, reducing the heat exchange between the surrounding environment of the battery pack and the outside world, which is beneficial to keep the battery pack in a suitable working environment, thereby helping to extend the service life of the battery pack.

[0037] Preferably, the environmental adjustment component further comprises:

[0038] A water removal chamber, which passes through the middle of the air inlet pipe to divide the air inlet pipe into two sections, and a first connecting port and a second connecting port are respectively provided at both ends of the water removal chamber, and the first connecting port and the second connecting port are respectively connected to the two sections of the air inlet pipe;

[0039] A partition plate is fixed inside the dewatering bin to divide the inside of the dewatering bin into two spaces on both sides connected at the bottom;

[0040] When the electric vehicle is driving on a rainy day, the air flow entering from the air vent is accompanied by rainwater. If the rainwater enters the inner box, the battery pack may be damaged. At this time, a water removal bin is provided so that the airflow can enter the inner part of the water removal bin in the middle when flowing through the air inlet pipe. Under the action of the partition inside the water removal bin, the airflow drives the rainwater to hit the partition, so that the rainwater is blocked by the partition and drips into the inner part of the water removal bin. After passing through the water removal bin, the airflow continues to flow along the air vent, which is conducive to removing the rainwater carried in the airflow and preventing the accumulation of rainwater inside the inner box and causing damage to the battery pack.

[0041] Preferably, the environmental adjustment component further comprises:

[0042] An exhaust pipe fixedly connected to the bottom of the wind-driven bin;

[0043] a third solenoid valve, fixed inside the exhaust duct;

[0044] In cold winter, the first solenoid valve and the second solenoid valve are in a closed state, reducing the heat exchange between the surrounding environment of the battery pack and the outside world, thereby helping to keep the battery pack in a suitable working environment, thereby helping to extend the service life of the battery pack;

[0045] However, closing the first solenoid valve and the second solenoid valve during the driving of the electric vehicle will prevent the airflow from being discharged, thereby interfering with the utilization of wind power generation. At this time, an exhaust duct is set and the third solenoid valve is opened, so that the airflow can be discharged from the exhaust duct, thereby avoiding interference with wind power generation. When it is necessary to open the first solenoid valve and the second solenoid valve, the third solenoid valve is closed to ensure that the airflow passes through the inner box, which is beneficial to avoid interference with the airflow path.

[0046] Preferably, the environmental adjustment component further comprises:

[0047] A water cooling pipe is spirally arranged and fixed inside the inner box;

[0048] A first water pipe, one end of which is fixedly connected to the top of the water cooling pipe, and the other end of which is fixedly connected to the water removal tank;

[0049] A second water pipe, one end of which is fixedly connected to the bottom of the water cooling pipe, and the other end of which is fixedly connected to the water removal tank;

[0050] a second rotating sleeve, wherein the first rotating sleeve drives the second rotating sleeve to rotate;

[0051] A first bevel gear, coaxially fixed to the outside of the second rotating sleeve;

[0052] An impeller is rotatably mounted inside the first water pipe, the rotating shaft of the impeller penetrates the side wall of the first water pipe and then extends out to be coaxially fixed with a second bevel gear, the second bevel gear is meshed with the first bevel gear;

[0053] After rainwater enters the interior of the dewatering bin, it will accumulate inside the dewatering bin. At this time, the first water pipe and the second water pipe connect the interior of the dewatering bin and the water-cooling pipe, so that water forms a passage between the water-cooling pipe and the first water pipe, the second water pipe, and the dewatering bin. At this time, when the wind drives the first rotating sleeve to rotate, the first rotating sleeve drives the second rotating sleeve to rotate, the second rotating sleeve drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear meshing therewith to rotate, and the second bevel gear drives the impeller to rotate. After the impeller rotates, it drives the water flow inside the first water pipe to flow, so that the water flow forms a water flow circulation between the water-cooling pipe and the first water pipe, the second water pipe, and the dewatering bin, thereby driving the water flow to pass through the interior of the inner box. When the water flows inside the inner box, the interior of the inner box can be further water-cooled, thereby improving the heat dissipation effect inside the inner box.

[0054] Preferably, the environmental adjustment component further comprises:

[0055] A plurality of heat conducting sheets are fixed in a linear array at the middle of the water cooling tube and located between the two battery packs;

[0056] A plurality of support frames, respectively fixed on the side walls of the water cooling tube and the heat conducting sheet, for supporting the battery pack, and the support frames are made of heat conducting metal;

[0057] A plurality of support frames, respectively fixed on the side walls of the water cooling tube and the heat conducting sheet, for supporting the battery pack, and the support frames are made of heat conducting metal;

[0058] The support frame can support and install the battery pack. The support frame and the heat conductive sheet can conduct the heat generated when the battery pack is working. The support frame and the heat conductive sheet are located at the center of the air flow path and are connected to the water cooling pipe. The water cooling pipe is made of heat conductive material, which further enhances the heat conduction effect, helps to improve the heat dissipation of the battery pack environment, and thus helps to extend the service life of the battery pack.

[0059] Preferably, the environmental adjustment component further comprises:

[0060] A first plug-in slot is provided on the top of the rotating shaft of the generator;

[0061] A second plug-in slot is provided at the bottom of the second rotating sleeve;

[0062] A cross plug-in rod is vertically slidably inserted in the first rotating sleeve, and two ends of the cross plug-in rod are respectively plugged and adapted with the first plug-in slot and the second plug-in slot;

[0063] A bracket, fixed to the top of the generator;

[0064] A cylinder is fixed to the top of the bracket, and the cylinder drives the cross-connecting rod to move vertically through a telescopic rod;

[0065] After the cylinder is started, the cross-connecting rod is driven to move vertically through the telescopic rod. When the cross-connecting rod moves upward to be inserted into the second plug-in slot and the bottom is separated from the first plug-in slot, the cross-connecting rod is only connected to the second rotating sleeve, so that when the first rotating sleeve rotates, only the second rotating sleeve is driven to rotate, so that the power of the airflow only drives the water flow to flow for heat dissipation. When the cross-connecting rod moves downward to be inserted into the first plug-in slot and the bottom is separated from the second plug-in slot, the cross-connecting rod is only connected to the rotating shaft of the generator, so that when the first rotating sleeve rotates, only the rotating shaft of the generator is driven to rotate, so that the power of the airflow is only used for the conversion of wind energy into electrical energy, which is beneficial to only support a single item of wind energy utilization when the wind force is insufficient. When the wind force is sufficient, the upper and lower ends of the cross-connecting rod are respectively plugged into the first plug-in slot and the second plug-in slot, so that when the first rotating sleeve rotates, the second rotating sleeve and the rotating shaft of the generator are driven to rotate at the same time, which is beneficial to make full use of wind energy to supplement the lack of kinetic energy recovered by wheel rotation when the battery vehicle decelerates or brakes, thereby improving the efficiency of continuous power conversion.

[0066] Preferably, the environmental adjustment component further comprises:

[0067] Water, contained in the dewatering tank;

[0068] A connecting pipe, one end of which is fixedly connected to the second connecting port, and the other end of which is located inside the water, and the opening of the connecting pipe is located on a side close to the first connecting port, and the opening is higher than the bottom edge of the partition;

[0069] A filter plate is fixed inside the water removal tank, and the filter plate is located below the water surface and the opening;

[0070] There is a lot of dust in the air. When the airflow is used to dissipate heat around the battery pack, the dust is deposited on the surface of the battery pack, which will affect the service life of the battery pack. At this time, water is placed inside the dewatering bin, and the incoming airflow is guided to below the surface of the water through a connecting pipe, so that the airflow enters the dewatering bin from underwater. At this time, the dust in the airflow is mixed into the water during the process of being discharged upward from underwater, which is conducive to removing impurities in the airflow, thereby helping to avoid the deposition of dust on the surface of the battery pack.

[0071] By setting the filter plate, when the dust is mixed in the water, it is located above the filter plate, and the water under the filter plate is clean water flow, so that when the water flow enters the water cooling pipe and the first water pipe, the second water pipe, and the dewatering tank, the pipe blockage is reduced;

[0072] By arranging replaceable water-absorbing material on the side wall of the air inlet pipe, the water vapor in the air flow can be absorbed when the air flow enters the interior of the air inlet pipe after passing through the water, which helps to prevent a small amount of water vapor from entering the interior of the inner box and causing damage to the battery pack.

[0073] Compared with the prior art, the present invention has the following beneficial effects:

[0074] 1. The present invention adjusts the interior of the power box to a suitable environment by setting an environmental adjustment component, so that the battery pack inside the power box can be charged and discharged in a suitable environment, which helps to avoid the battery pack being damaged due to an unsuitable environment during the charging and discharging process.

[0075] 2. The present invention converts wind energy into electrical energy by setting up a wind energy supplement component, thereby improving the power conversion efficiency of the battery vehicle.

[0086] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0087] like Figures 1 to 8 The green, low-carbon energy sustainable battery vehicle electric energy conversion device shown includes a power box 1 and a generator 2, wheels, and motors, wherein the power box 1 supplies power to the motor to drive the wheels to rotate. When the throttle of the battery vehicle is released, the motor stops driving. At this time, the rotation of the wheel drives the generator 2 to rotate through the transmission system to convert power and generate electricity, and the power box 1 stores the electric energy converted by the rectifier, and also includes:

[0088] The power supply box 1 includes two battery packs 101;

[0089] A control unit, the control unit is used to control the generator 2 to switch to the connected battery pack 101 when the internal power of one of the battery packs 101 exceeds 80%, control the generator 2 to stop generating electricity when the internal power of two battery packs 101 exceeds 100%, and control the generator 2 to switch to the connected battery pack 101 for electric energy storage when the internal power of one of the battery packs 101 is less than 20%;

[0090] The environment adjustment component is installed on the power box 1 and is used to adjust the power box 1 to a suitable power conversion environment. The control unit is also used to control the generator 2 to stop generating electricity when the environment of the power box 1 is not suitable.

[0091] A wind energy supplement component is installed on the power box 1 and is used to convert wind energy into electrical energy for storage during the movement of the battery vehicle;

[0092] However, when the vehicle is decelerating or braking to recover mechanical energy, it is necessary to convert the recovered mechanical energy into electrical energy and store it in the battery. However, during the storage or deployment of the battery car, the battery is stored inside the battery car. In hot weather, if the battery car is exposed to direct sunlight, the temperature of the battery storage location will rise sharply in a short period of time, making the battery environment unsuitable. At this time, if the recovered electrical energy is stored in the battery, it will accelerate the damage of the battery.

[0093] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: during the driving of the battery vehicle, the battery pack 101 inside the power box 1 provides electric energy to the motor, so that the motor converts the electric energy into mechanical energy to drive the wheels to rotate, thereby driving the battery vehicle to drive through the rotation of the wheels. When the driver releases the throttle of the battery vehicle, the control unit detects that the throttle is released. At this time, the control unit controls the generator 2 and the transmission system to connect the wheels, so that the rotation of the wheels drives the generator 2 to rotate through the transmission system. After the generator 2 rotates, the mechanical energy is converted into electric energy, and the electric energy is stored through the battery pack 101 after conversion by the rectifier, so that when braking or decelerating, the electric energy is recovered through the rotation of the wheels;

[0094] By setting two battery packs 101, when electric energy is recovered, if the power of one of the battery packs 101 is ≥ 80%, the control unit detects the power of the battery pack 101, and controls the generator 2 to switch to connect to the other battery pack 101, which is conducive to avoiding continuous charging of the battery pack 101 when the power of the battery pack 101 exceeds 80%;

[0095] When the control unit detects that the power level of one of the battery packs 101 is ≤ 20%, the generator 2 is controlled to switch to the battery pack 101, thereby preventing the battery pack 101 from being damaged due to the power level of the battery pack 101 being less than 20%. In summary, through the adjustment of the control unit, the power level of the battery pack 101 tends to be maintained between 20% and 80%, thereby extending the service life of the battery and preventing the battery pack 101 from being quickly damaged during the process of recycling electric energy.

[0096] When the control unit detects that the power levels of the two battery packs 101 are both ≥ 80%, the generator 2 is connected to the two battery packs 101 in sequence for charging. If the power levels of the two battery packs 101 are both fully charged, the control unit controls the generator 2 to stop kinetic energy recovery, thereby helping to avoid overcharge damage to the battery packs 101.

[0097] The control unit is also used to control the two battery packs 101 of the machine to charge one for kinetic energy recovery and discharge the other to drive the wheels to rotate, so as to avoid frequent charging and discharging of the same battery pack 101 causing damage to the battery pack 101;

[0098] The environment adjustment component is set to adjust the internal environment of the power box 1, and adjust the inside of the power box 1 to a suitable environment, so that the battery pack 101 inside the power box 1 can be charged and discharged in a suitable environment, which is helpful to avoid the battery pack 101 being damaged due to an unsuitable environment during the charging and discharging process;

[0099] The wind energy supplement component can convert wind energy into electrical energy, thereby improving the power conversion efficiency of the battery vehicle, which is beneficial to enhancing the power of the battery vehicle when the battery vehicle is short of power, and is beneficial to improving the battery vehicle's endurance;

[0100] In summary, by controlling the charging and discharging of the battery pack 101 and the charging and discharging environment, the battery pack 101 can be charged and discharged in a suitable environment and state to reduce damage to the battery during the continuous power conversion process and extend the service life of the battery pack 101.

[0101] As an optional embodiment, the wind energy supplement component includes:

[0102] The air inlet 3, the opening of the air inlet 3 faces the front of the battery vehicle;

[0103] The wind-driven chamber 302 is connected to the air inlet 3 through the air inlet pipe 301;

[0104] The fan blades 303 are rotatably mounted inside the wind-driven compartment 302;

[0105] The wind driving gear 304 is coaxially fixed to the bottom of the rotating shaft of the fan blade 303;

[0106] The synchronous wheel 306 rotates synchronously with the rotating shaft of the generator 2 through the first rotating sleeve 307, and the synchronous wheel 306 and the wind driving gear 304 are synchronously driven through the synchronous belt 305;

[0107] During the driving of the battery vehicle, the airflow impacts the battery vehicle, so that the airflow enters from the air inlet 3 under the action of wind force, and then enters the interior of the wind-driven compartment 302 along the air inlet pipe 301. When the airflow enters from the air inlet 3, the cross-sectional area of ​​the air inlet 3 is large, while the cross-sectional area of ​​the air inlet pipe 301 is small, so that the wind speed of the airflow is accelerated when passing through the air inlet pipe 301, so that when the airflow enters the interior of the wind-driven compartment 302 through the connection between the air inlet pipe 301 and the wind-driven compartment 302, the driving force on the fan blades 303 inside the wind-driven compartment 302 is increased, thereby driving the fan blades 303. 03 rotates, and then the airflow is discharged from the bottom of the wind-driven bin 302. The fan blades 303 rotate and drive the wind-driven gear 304 connected thereto to rotate. The wind-driven gear 304 drives the synchronous wheel 306 to rotate through the transmission of the synchronous belt 305. The synchronous wheel 306 rotates and drives the first rotating sleeve 307 to rotate, thereby driving the rotating shaft of the generator 2 to rotate to generate electricity, thereby realizing auxiliary power generation through the action of wind power, which is beneficial to the recovery of the kinetic energy of the wheels of the battery vehicle when the kinetic energy of the battery vehicle is insufficient. The wind force generated by the relative action during the movement of the battery vehicle can be used for wind energy recovery, thereby helping to improve the endurance of the battery vehicle.

[0108] As an optional embodiment, the environmental adjustment component includes:

[0109] The inner box body 103 is fixed inside the power box 1, and a vacuum layer 102 is formed between the inner box body 103 and the inner wall of the power box 1;

[0110] The setting of the inner box 103 forms a vacuum layer 102 between the inner box 103 and the inner wall of the power box 1. The heat conduction efficiency inside the vacuum layer 102 is poor, which helps to slow down the conduction speed of the external high temperature or low temperature to the inside of the inner box 103. This helps to avoid the external high temperature or low temperature from quickly interfering with the inside of the inner box 103 when the electric vehicle is placed in the external environment, making the working environment of the battery pack 101 inside the inner box 103 unsuitable, thereby affecting the service life of the battery pack 101.

[0111] As an optional embodiment, the environmental adjustment component further includes:

[0112] The air inlet 4 is opened through the top of the power box 1, the bottom of the air inlet 4 is connected to the inside of the inner box 103, and the top of the air inlet 4 is fixedly connected to the bottom of the wind-driven compartment 302;

[0113] The first solenoid valve 401 is fixedly installed inside the air inlet 4;

[0114] The air outlet 402 is penetrated and opened at the bottom of the power supply box 1, and the top of the air outlet 402 communicates with the inside of the inner box body 103;

[0115] The second solenoid valve 403 is fixedly installed inside the air outlet 402;

[0116] The air inlet 4 is communicated with the bottom of the wind power driving chamber 302, so that the air flow discharged from the bottom of the wind power driving chamber 302 passes through the air inlet 4 and enters the inside of the inner box body 103, and then the air flow passes through the entire inner box body 103 and is discharged from the air outlet 402;

[0117] In the hot summer, when the battery-powered vehicle is not started, the first solenoid valve 401 and the second solenoid valve 403 are in the closed state, so that there is no air flow exchange between the inside of the inner box body 103 and the outside world, thereby reducing heat exchange. When the battery-powered vehicle starts to move, the first solenoid valve 401 and the second solenoid valve 403 are opened. Since there is an air flow when the battery-powered vehicle moves relative to the air, in the summer temperature, when the flowing air passes through the inside of the inner box body 103, it will not cause the temperature around the battery pack 101 inside the inner box body 103 to exceed the appropriate temperature, and it will also drive the temperature generated when the battery pack 101 works to be discharged due to driving the air flow, thereby facilitating heat dissipation around the battery pack 101, thereby facilitating keeping the battery pack 101 in a suitable temperature environment for charging and discharging, and thereby facilitating extending the service life of the battery pack 101;

[0118] In the cold winter, the first solenoid valve 401 and the second solenoid valve 403 are in the closed state, reducing the heat exchange between the environment around the battery pack 101 and the outside world, thereby facilitating keeping the battery pack 101 in a suitable working environment, and thereby facilitating extending the service life of the battery pack 101.

[0119] As an optional embodiment, the environment adjustment component further includes:

[0120] The water removal bin 5 penetrates through the middle of the air inlet pipe 301 to divide the air inlet pipe 301 into two sections. The two ends of the water removal bin 5 are respectively provided with a first connection port 502 and a second connection port 503, and the first connection port 502 and the second connection port 503 are respectively communicated with the two sections of the air inlet pipe 301;

[0121] The partition plate 501 is fixed inside the water removal bin 5 to divide the inner part of the water removal bin 5 into two side spaces with a bottom connection;

[0122] When the electric vehicle is driving on a rainy day, the air flow entering through the air duct 3 is accompanied by rainwater. If the rainwater enters the interior of the inner box 103, there is a possibility that the battery pack 101 will be damaged. At this time, by providing a dewatering bin 5, the airflow will enter the interior of the dewatering bin 5 in the middle when flowing through the air inlet pipe 301. Under the action of the partition 501 inside the dewatering bin 5, the airflow drives the rainwater to hit the partition 501, so that the rainwater is blocked by the partition 501 and then drips into the interior of the dewatering bin 5. After passing through the dewatering bin 5, the airflow continues to flow along the air duct 3, which is beneficial to remove the rainwater carried in the airflow and to avoid the accumulation of rainwater inside the inner box 103, causing damage to the battery pack 101.

[0123] As an optional embodiment, the environmental adjustment component further includes:

[0124] An exhaust pipe 6 is fixedly connected to the bottom of the air-driven bin 302;

[0125] The third solenoid valve 601 is fixed inside the exhaust pipe 6;

[0126] In cold winter, the first solenoid valve 401 and the second solenoid valve 403 are in a closed state, reducing the heat exchange between the surrounding environment of the battery pack 101 and the outside world, thereby helping to keep the battery pack 101 in a suitable working environment, thereby helping to extend the service life of the battery pack 101;

[0127] However, closing the first solenoid valve 401 and the second solenoid valve 403 during the driving of the electric vehicle will prevent the airflow from being discharged, thereby interfering with the utilization of wind power generation. At this time, an exhaust duct 6 is set and the third solenoid valve 601 is opened, so that the airflow can be discharged from the exhaust duct 6, thereby avoiding interference with wind power generation. When it is necessary to open the first solenoid valve 401 and the second solenoid valve 403, the third solenoid valve 601 is closed to ensure that the airflow passes through the inner box 103, which is beneficial to avoid interference with the airflow path.

[0128] As an optional embodiment, the environmental adjustment component further includes:

[0129] The water cooling pipe 7 is spirally arranged and fixed inside the inner box 103;

[0130] A first water pipe 701, one end of which is fixedly connected to the top of the water cooling pipe 7, and the other end of which is fixedly connected to the water removal tank 5;

[0131] A second water pipe 702, one end of which is fixedly connected to the bottom of the water cooling pipe 7, and the other end of which is fixedly connected to the water removal tank 5;

[0132] The second rotating sleeve 703, the first rotating sleeve 307 drives the second rotating sleeve 703 to rotate;

[0133] The first bevel gear 704 is coaxially fixed to the outside of the second rotating sleeve 703;

[0134] The impeller 706 is rotatably mounted inside the first water pipe 701. The rotating shaft of the impeller 706 penetrates the side wall of the first water pipe 701 and extends out to be coaxially fixed with a second bevel gear 705. The second bevel gear 705 is meshed with the first bevel gear 704.

[0135] After rainwater enters the dewatering bin 5, it will accumulate inside the dewatering bin 5. At this time, the first water pipe 701 and the second water pipe 702 are connected to the inside of the dewatering bin 5 and the water cooling pipe 7, so that water flows through a passage between the water cooling pipe 7 and the first water pipe 701, the second water pipe 702, and the dewatering bin 5. At this time, when the wind drives the first rotating sleeve 307 to rotate, the first rotating sleeve 307 drives the second rotating sleeve 703 to rotate, the second rotating sleeve 703 drives the first bevel gear 704 to rotate, and the first bevel gear 704 drives the meshing The second bevel gear 705 rotates, and the second bevel gear 705 drives the impeller 706 to rotate. After the impeller 706 rotates, it drives the water inside the first water pipe 701 to flow, so that the water forms a water circulation between the water-cooling pipe 7 and the first water pipe 701, the second water pipe 702, and the dewatering tank 5, thereby driving the water to flow through the interior of the inner box 103. When the water flows inside the inner box 103, the interior of the inner box 103 can be further water-cooled, thereby improving the heat dissipation effect inside the inner box 103.

[0136] As an optional embodiment, the environmental adjustment component further includes:

[0137] A plurality of heat conducting sheets 8 are fixed in a linear array at the middle of the water cooling tube 7 and are located between the two battery packs 101;

[0138] A plurality of support frames 801 are respectively fixed on the side walls of the water cooling tube 7 and the heat conducting sheet 8 to support the battery pack 101, and the support frames 801 are made of heat conducting metal;

[0139] The support frame 801 can support and install the battery pack 101. The setting of the support frame 801 and the heat conductive sheet 8 can conduct the heat generated by the battery pack 101 when it is working. The support frame 801 and the heat conductive sheet 8 are located at the center of the path through which the airflow passes, and are connected to the water cooling pipe 7. The water cooling pipe 7 is made of a heat-conducting material, thereby further enhancing the heat conduction effect, which is beneficial to improving the heat dissipation of the environment in which the battery pack 101 is located, thereby helping to extend the service life of the battery pack 101.

[0140] As an optional embodiment, the environmental adjustment component further includes:

[0141] The first plug-in slot 901 is provided at the top of the rotating shaft of the generator 2;

[0142] The second plug-in slot 902 is provided at the bottom of the second rotating sleeve 703;

[0143] The cross plug-in rod 9 is vertically slidably inserted into the first rotating sleeve 307, and the two ends of the cross plug-in rod 9 are respectively plugged and adapted with the first plug-in groove 901 and the second plug-in groove 902;

[0144] Bracket 903, fixed on the top of the generator 2;

[0145] The cylinder 904 is fixed to the top of the bracket 903, and the cylinder 904 drives the cross-connecting rod 9 to move vertically through the telescopic rod;

[0146] After the cylinder 904 is started, the cross-connecting rod 9 is driven to move vertically through the telescopic rod. When the cross-connecting rod 9 moves upward to be inserted into the second plug-in slot 902 and the bottom is separated from the first plug-in slot 901, the cross-connecting rod 9 is only connected to the second rotating sleeve 703, so that when the first rotating sleeve 307 rotates, only the second rotating sleeve 703 is driven to rotate, so that the power of the airflow only drives the water flow to flow for heat dissipation. When the cross-connecting rod 9 moves downward to be inserted into the first plug-in slot 901 and the bottom is separated from the second plug-in slot 902, the cross-connecting rod 9 is only connected to the rotating shaft of the generator 2, so that the first rotating sleeve When 307 rotates, it only drives the shaft of the generator 2 to rotate, so that the power of the airflow is only used for the conversion of wind energy into electrical energy, which is beneficial to only support a single item of wind energy utilization when the wind is insufficient. When the wind is sufficient, the upper and lower ends of the cross plug rod 9 are respectively plugged into the first plug slot 901 and the second plug slot 902, so that when the first rotating sleeve 307 rotates, it also drives the second rotating sleeve 703 and the shaft of the generator 2 to rotate, which is beneficial to fully utilize the wind energy to make up for the lack of kinetic energy recovered by the wheel rotation when the battery vehicle decelerates or brakes, thereby improving the efficiency of continuous power conversion.

[0147] As an optional embodiment, the environmental adjustment component further includes:

[0148] Water 10 is contained in the dewatering tank 5;

[0149] A connecting pipe 1001, one end of which is fixedly connected to the second connecting port 503, and the other end of which is located inside the water 10, and an opening 1002 of the connecting pipe 1001 is located on a side close to the first connecting port 502, and the opening 1002 is higher than the bottom edge of the partition 501;

[0150] The filter plate 11 is fixed inside the water removal tank 5, and the filter plate 11 is located below the water surface of the water 10 and the opening 1002;

[0151] There is a lot of dust in the air. When the airflow is used to dissipate heat around the battery pack 101, the dust is deposited on the surface of the battery pack 101, which will affect the service life of the battery pack 101. At this time, water 10 is placed inside the dewatering bin 5, and the incoming airflow is guided to below the surface of the water 10 through the connecting pipe 1001, so that the airflow enters the dewatering bin 5 from underwater. At this time, the dust in the airflow is mixed into the water 10 during the process of being discharged upward from underwater, which is conducive to removing impurities in the airflow, thereby helping to avoid the deposition of dust on the surface of the battery pack 101.

[0152] By setting the filter plate 11, when the dust is mixed in the water 10, it is located above the filter plate 11, and the water 10 under the filter plate 11 is a clean water flow, so that when the water flow enters the water cooling pipe 7 and the first water pipe 701, the second water pipe 702, and the dewatering tank 5, the pipe is less likely to be blocked;

[0153] By arranging a replaceable water-absorbing material on the side wall of the air inlet pipe 301, the water vapor in the air flow can be absorbed when the air flow enters the interior of the air inlet pipe 301 after passing through the water 10, which helps to prevent a small amount of water vapor from entering the interior of the inner box 103 and causing damage to the battery pack 101.

[0154] The working principle of the present invention is as follows: during the driving of the battery vehicle, the battery pack 101 inside the power box 1 provides electric energy to the motor, so that the motor converts the electric energy into mechanical energy to drive the wheels to rotate, thereby driving the battery vehicle to drive through the rotation of the wheels. When the driver releases the throttle of the battery vehicle, the control unit detects that the throttle is released, and at this time the control unit controls the generator 2 and the transmission system to connect the wheels, so that the rotation of the wheels drives the generator 2 to rotate through the transmission system. After the generator 2 rotates, the mechanical energy is converted into electric energy, and after conversion by the rectifier, the electric energy is stored in the battery pack 101, so that when braking or decelerating, the electric energy is recovered through the rotation of the wheels;

[0155] By setting two battery packs 101, when electric energy is recovered, if the power of one of the battery packs 101 is ≥ 80%, the control unit detects the power of the battery pack 101, and controls the generator 2 to switch to connect to the other battery pack 101, which is conducive to avoiding continuous charging of the battery pack 101 when the power of the battery pack 101 exceeds 80%;

[0156] When the control unit detects that the power of one of the battery packs 101 is ≤ 20%, it controls the generator 2 to switch to connect to this battery pack 101, which helps to avoid the situation that the battery pack 101 is damaged due to the power being less than 20%. In summary, through the adjustment of the control unit, the power of the battery pack 101 is controlled to tend to remain between 20% and 80%, which helps to extend the service life of the battery and avoid the situation that the battery pack 101 is quickly damaged during the process of recovering electric energy;

[0157] When the control unit detects that the power of both battery packs 101 is ≥ 80%, the generator 2 connects to both battery packs 101 in sequence for charging. If the power of both battery packs 101 is fully charged, the control unit controls the generator 2 to stop kinetic energy recovery, which helps to avoid the situation of overcharging damage to the battery pack 101;

[0158] The control unit is also used to control one of the two battery packs 101 to perform kinetic energy recovery charging and the other to perform discharging to drive the wheels to rotate, so as to avoid the situation that the same battery pack 101 is frequently charged and discharged, resulting in damage to the battery pack 101;

[0159] The setting of the environmental adjustment component adjusts the internal environment of the power supply box 1 to an appropriate environment, so that the battery pack 101 inside the power supply box 1 can charge and discharge in an appropriate environment, which helps to avoid the situation that the battery pack 101 is damaged due to inappropriate environment during the charging and discharging process;

[0160] The wind energy supplement component can convert wind energy into electric energy, thereby improving the conversion efficiency of the continuous driving force of the battery car. It helps to enhance the effect of the continuous driving force of the battery car when the electric energy of the battery car is insufficient and is beneficial to improving the endurance of the battery car;

[0161] In summary, through the control of the charging and discharging of the battery pack 101 and the control of the charging and discharging environment, the battery pack 101 can perform charging and discharging operations in an appropriate environment and state, so as to slow down the damage caused during the conversion of the continuous driving force of the battery and extend the service life of the battery pack 101.
