In a specific implementation, communication connections may be employed between the battery management system 220 and the power cell body 210, between the vehicle controller 310 and the voltage control module 320, and between the vehicle controller 310 and the charge/discharge module 330. The housing assembly 100 is provided with a first interface group 410 and a second interface group 420, and the voltage control module 320 can obtain the electric energy of the power battery body 210 after receiving the first control signal sent by the vehicle controller 310, adjust the voltage accordingly, and then supply power to the equipment with the voltage consistent with the required electric energy on the vehicle through the part of the first interface group 410 correspondingly connected with the power battery body.

According to the integrated electronic control system of the embodiment of the application, the power battery pack 200 and the electronic control unit pack 300 are both arranged in the shell assembly 100, so that the power battery body 210 in the shell assembly 100 is further electrically connected with the battery management system 220, and the whole vehicle controller 310 is respectively electrically connected with the voltage control module 320 and the charging and discharging module 330; the high-voltage distribution box 230 is electrically connected with the battery management system 220, the voltage control module 320 and the charging and discharging module 330 are electrically connected with the high-voltage distribution box 230, and the interface group 400 is arranged on the shell assembly 100, so that part of the first interface group 410 corresponds to and is connected with the voltage control module 320, and the second interface group 420 corresponds to and is connected with the charging and discharging module 330, thereby, on the basis of meeting the power requirement of a vehicle, the integrated electric control system omits a bracket required by each part when being independently installed, and the space occupation is small and the cost can be saved.

The specific composition and operation of the voltage control module 320 and the charge/discharge module 330 will be described below.

In some embodiments, the voltage control module 320 includes a high voltage to low voltage sub-module, the first interface group 410 includes a high voltage power transmission interface 411 and a low voltage power transmission interface 412, the high voltage power transmission interface 411 is connected to the high voltage distribution box 230, and the low voltage power transmission interface 412 is connected to the high voltage to low voltage sub-module.

In particular, the high voltage to low voltage electronic module is used to supply power to low voltage devices on the vehicle, which may include lighting systems, such as lighting devices for headlights, taillights, brake lights, etc., of the vehicle, by way of example; control systems such as car computers, dashboard displays, audio systems may also be included.

In a specific implementation, the high-voltage to low-voltage electronic module may be at least one of a direct current-direct current Converter (DC-DC Converter), a step-down module and a transformer, and it is understood that the above three devices may all implement a function of converting high voltage to low voltage. Illustratively, a transformer is a device that converts alternating current electrical energy from one voltage level to another, consisting of one or more coils, that converts high voltage electricity to low voltage electricity by employing electromagnetic induction principles.

In specific implementation, at least one of the dc-dc converter, the step-down module and the transformer is one or more, and the housing assembly 100 is provided with a plurality of low-voltage power transmission interfaces 412, so that each low-voltage power transmission interface 412 is in one-to-one correspondence with each high-voltage power transmission low-voltage sub-module and is electrically connected, that is, the high-voltage power transmission low-voltage sub-module is plugged into the connection end of the low-voltage power transmission interface 412 through a high-voltage wire bundle adapted to the corresponding low-voltage power transmission interface 412; and the low-voltage equipment is plugged into the plugging end of the low-voltage power transmission interface 412 through a high-voltage wire harness matched with the corresponding low-voltage power transmission interface 412. Thus, the power transmission efficiency is advantageously improved when power is supplied to different low-voltage devices.

The high-voltage distribution box 230 is plugged into the connection end of the high-voltage transmission interface 411 through a high-voltage wire harness matched with the high-voltage transmission interface 411, so that the high-voltage distribution box 230 can transmit electric energy for an electric air conditioner or other high-voltage equipment on a vehicle through the high-voltage transmission interface.

The motor controller 332 (Microcontroller Unit, MCU) is used to control and drive the drive motor on the vehicle. In a specific implementation, the motor controller 332 is plugged into the connection end of the output interface 422 through a high-voltage wire harness adapted to the output interface 422, and the driving motor is plugged into the plugging end of the output interface 422 through a high-voltage wire harness adapted to the output interface 422. It will be appreciated that the driving motor is responsible for converting electrical energy into mechanical energy to drive the vehicle, and through the above arrangement, the motor controller 332 can supply the electrical energy of the power battery body 210 to the driving motor via the output interface 422, so as to provide the driving motor with the electrical energy necessary for operation.

Further, the motor controller 332 may also control the operation state of the driving motor by sending a control signal to the driving motor. For example, in implementation, the vehicle controller 310 electrically connected to the motor controller 332 may send a third control signal to the motor controller 332, where the third control signal may be one of a driving signal and a braking signal.

When the motor controller 332 receives the driving signal, it will send a first command to the driving motor, and the driving motor will consume the electric energy of the power battery body 210 according to the first command to convert into mechanical energy to drive the vehicle to run; when the motor controller 332 receives the braking signal, it will send a second command to the driving motor, and the driving motor will perform the auxiliary braking of energy recovery according to the second command, i.e. the mechanical energy is converted into electrical energy and stored in the power battery body 210 after passing through the motor controller 332.

A slow Charger 331 (On-Board Charger, OBC) is used to charge the power cell body 210. In specific implementation, the slow charging machine 331 is plugged into the connection end of the input interface 421 through a high-voltage wire harness matched with the input interface 421, and a charging gun of an external charging pile is plugged into the plugging end of the input interface 421; the vehicle controller 310 electrically connected to the slow charge machine 331 may monitor and control the charging process.

For example, after the vehicle controller 310 sends the second control signal to the slow charger 331, the slow charger 331 starts to receive the electric energy transmitted from the charging gun and transmits the electric energy to the power battery body 210.

Referring to fig. 2, to realize the connection between the vehicle controller 310 and the high-voltage to low-voltage sub-module and the connection between the vehicle controller 310 and the charge and discharge module 330, in a specific example, the integrated electronic control system further includes a low-voltage line set 500, where the low-voltage line set 500 includes a first low-voltage line 510, a second low-voltage line 520, and a third low-voltage line 530, the high-voltage to low-voltage sub-module is electrically connected to the vehicle controller 310 through the first low-voltage line 510, and the slow charge machine 331 is electrically connected to the vehicle controller 310 through the second low-voltage line 520, and the motor controller 332 is electrically connected to the vehicle controller 310 through the third low-voltage line 530.

In particular, the low-voltage line set 500 is located in the housing assembly 100, so that the vehicle controller 310, the high-voltage to low-voltage sub-module and the charge and discharge module 330 are integrated in the housing assembly 100 through the low-voltage line set 500, the vehicle controller 310 can transmit control signals to the high-voltage to low-voltage sub-module through the first low-voltage line 510, and can transmit control signals to the slow charger 331 and the motor controller 332 through the second low-voltage line 520 and the third low-voltage line 530, respectively.

With continued reference to fig. 2, in a specific example, the integrated electronic control system further includes a high voltage stack 600, the high voltage stack 600 including a first high voltage line 610, a second high voltage line 620, a third high voltage line 630, a fourth high voltage line 640, and a fifth high voltage line 650.

By arranging the high-voltage wire set 600, in the process of charging the power battery body 210 or supplying power to other electric equipment by the power battery body 210, the high-voltage wire has better insulating property and voltage-resisting capability, so that the safe transmission of electric energy can be ensured, and the reliability of electric energy transmission can be improved.

In some embodiments, the integrated electronic control system further comprises a cooling system (not shown) comprising a radiator, a first conduit, and a first control valve; the radiator is connected with the high-voltage power conversion low-voltage power module, the slow charging machine 331, the motor controller 332, the power battery body 210 and the driving motor sequentially through a first pipeline, the first control valve is arranged on the first pipeline and is electrically connected with the whole vehicle controller 310, and the whole vehicle controller 310 is used for controlling the opening and closing of the first control valve so as to be communicated with or close the first pipeline.

Specifically, by setting the cooling system to cool the power battery body 210 and the electric control unit group 300 inside the housing assembly 100, the problem that each component fails at high temperature during normal operation can be avoided, and the reliability and safety of each component in the operation process can be improved.

For example, in a scenario of hot summer weather or long-term running of the components resulting in scalding, the whole vehicle controller 310 controls the first control valve to be opened, so that the first pipeline is in a connected state, and therefore, the low-temperature cooling liquid generated by the radiator sequentially passes through the high-voltage to low-voltage electronic module, the slow charging machine 331, the motor controller 332, the power battery body 210 and the driving motor in the first pipeline, so as to perform heat dissipation on the components; the cooling liquid from the drive motor will take up the heat of the components and become a high temperature cooling liquid which in the first conduit flows further into the radiator and is cooled and stored.

In a specific example, the integrated electronic control system further includes a second pipe and a second control valve (not shown), one end of the second pipe is connected to the power battery body, the other end of the second pipe is connected to the driving motor, the second control valve is disposed on the second pipe, the second control valve is electrically connected to the whole vehicle controller, and the whole vehicle controller is used for controlling opening and closing of the second control valve to communicate or close the second pipe.

Here, in order to ensure that the power battery body 210 can perform normal discharging operation in a cold weather and low air temperature, the vehicle controller 310 controls the second control valve to be opened so that the second pipe is in a connected state, and thus, heat generated by operation of the driving motor flows into the second pipe and flows toward the power battery body 210, thereby heating the power battery body 210.

Referring to fig. 2, in some examples, the housing assembly 100 includes a first housing 101 and a second housing 102, the power cell body 210 and the battery management system 220 are disposed within the first housing 101, the high voltage distribution box 230 and the electronic control unit set 300 are disposed within the second housing 102, the interface set 400 is disposed on the second housing 102, and the first housing 101 is in communication with the interior of the second housing 102.

Through the arrangement, on the basis of fully utilizing the internal space of the shell assembly 100, the orderly arrangement of the components ensures that the high-voltage line group 600 and the low-voltage line group 500 are tidy and orderly in the trend of the interior of the shell assembly 100, thereby being beneficial to saving the working time of subsequent maintenance, fault investigation and other works; meanwhile, the space and the cost occupied by the brackets of the components are saved when the components are independently installed.

Further, when the electric equipment outside the second housing 102 is connected with the interface group 400 thereon, it is also beneficial to improve the order between the lines.

Referring to fig. 1, in some examples, interface group 400 further includes a fast charge interface 401, fast charge interface 401 being electrically connected to power cell body 210 via battery management system 220.

Specifically, by setting the fast charging interface 401 on the housing assembly 100, the fast charging of the power battery body 210 can be realized through the fast charging interface 401, which is beneficial to shortening the charging time and improving the charging power.
