With the increase of the storage quantity of new energy electric vehicles and the intelligent development of the electric vehicles, the cost and the performance of the whole vehicle become the focus of attention. In order to meet the low-cost and high-performance conditions, the electronic electric architecture gradually evolves from distributed to centralized, and the domain control technology is used more and more widely, wherein the power domain is an important plate of the new energy electric automobile, referring to fig. 4, fig. 4 is a block diagram of an existing power domain control system provided by another embodiment of the present application, it can be understood that, in order to reduce the cost of the related controller of the power system and improve the performance of the power system, a method commonly used in the market at present integrates high-voltage components (such as a motor, a speed reducer, a motor controller, a direct-current power supply converter, an alternating-current charger and a distribution box) of the power domain, and integrates part of functions of a main control part of a battery manager into a whole vehicle controller to form the power domain controller. However, the existing domain controller has more control functions, so that the number of pins of the connectors is more, and the power domain controller is built in the battery pack, so that when the battery pack is dead, the plurality of pins of the connectors are required to be plugged and unplugged when the battery pack is replaced, and then the removed battery pack is charged in the battery replacing station, so that great inconvenience is caused. Moreover, because the frequency of replacing the battery pack is frequent, in the life cycle of a product, even the plug of tens of thousands times needs to be met, and the plug-in pin of the power domain controller is required to have higher plug-in performance and reliability.
Referring to fig. 1, fig. 1 is a block diagram of a power domain control system according to an embodiment of the present application, it may be understood that a power domain control system includes: a battery pack 100, the battery pack 100 including a domain controller 110; the control execution module 200, the control execution module 200 is connected with the domain controller 110 in a communication manner; the sensing module 300, the sensing module 300 is connected with the control execution module 200 electrically; the execution module 400, the execution module 400 is electrically connected with the control execution module 200; the domain controller 110 is configured to control the sensing module 300 to collect signals by controlling the execution module 200, and the domain controller 110 is also configured to control the execution module 400 to operate by controlling the execution module 200.
It should be noted that, the control execution function and the sampling function of the domain controller 110 are independent, and the control execution module 200 is disposed outside the battery pack 100 as a sub-board of the domain controller 110, so that the resources of the connector pins of the battery pack 100 are reduced, and the connector pins of the domain controller 110 can be reduced from above 100 pins to within 20 pins, thereby facilitating the replacement of the battery pack 100.
According to one embodiment of the present application, after the control execution function and the sampling function are all external to the control execution module 200, the domain controller 110 only retains the controller area network (Controller Area Network, CAN) communication signal, the power signal and the related wake-up signal, when the operator starts the vehicle, the domain controller 110 obtains the wake-up signal input from the outside and wakes up the control execution module 200 according to the wake-up signal, and on the other hand, when the operator wakes up the control execution module 200 through the external module electrically connected to the control execution module 200, the control execution module 200 may further wake up the domain controller 110. The domain controller 110 mainly controls the sensing module 300 to collect signals through the control execution module 200, and also controls the execution module 400 to work through the control execution module 200. The control execution module 200 may generate a sampling signal at preset intervals, and control the sensing module 300 electrically connected to the control execution module 200 to perform sampling operation according to the sampling signal, and acquire data information transmitted after the sampling of the sensing module 300, for example: high-voltage interlocking signal acquisition, temperature acquisition and the like; on the other hand, when the operator needs to control the fan, the water pump or the high-voltage relay, the operator inputs the execution output signal to the control execution module 200, so that the control execution module 200 can obtain the execution output signal input by the operator, and control the corresponding execution module 400 to execute the operation corresponding to the execution output signal according to the execution output signal.
Specifically, the control execution module 200 may not only control the execution module 400 to execute a corresponding operation according to an execution output signal input by an operator, when the control execution module 200 analyzes the sampled data transmitted by the sensing module 300 to obtain that a certain sampled data is higher than a preset alert threshold, the control execution module 200 may also automatically send an execution output signal to a certain execution module 400 corresponding to the sampled data, so that the sampled data obtained by sampling the execution module 400 at the next moment of the sensing module 300 may be lower than the preset alert threshold. More specifically, when the control execution module 200 obtains that the temperature at the current time is higher than the preset warning threshold, the control execution module 200 will automatically send an execution output signal to the fan, so that the fan cools the current environment until the temperature value obtained by sampling at the next time is lower than the preset warning threshold.
It should be noted that, the communication connection in the application includes a CAN bus connection and a local interconnect network (Local Interconnect Network, LIN) connection, and the electrical connection includes connection through a hardware socket, and a specific connection mode is determined according to a function of the electric automobile, so that the application does not specifically limit the connection mode, and CAN meet signal transmission between components.
According to another embodiment of the present application, the control execution module 200 can be further connected with a plurality of hard-wire signals, and specific control functions should be formulated and designed according to actual requirements of the vehicle, which is not specifically limited in the present application.
Referring to fig. 3, fig. 3 is a block diagram of a control execution module 200 according to another embodiment of the present application, it is to be understood that the control execution module 200 further includes a main control chip 220 and a communication chip 240, the main control chip 220 is connected to the communication chip 240, the main control chip 220 is used for controlling the execution module 400, and the communication chip 240 is used for implementing communication connection between the control execution module 200 and the domain controller 110.
Referring to fig. 2, fig. 2 is a hardware structure diagram of a control execution module 200 according to another embodiment of the present application, where a main control chip 220 includes a plurality of external pins, and different external components and chips can be connected through the external pins, for example: the external pin is connected with different sensing components in the sensing module 300 to acquire gear signals, feedback signals of the fan, pressure signals, positions of a brake pedal, the rotating speed of the fan and the like; and can also be connected with different execution components in the execution module 400 through external pins so as to realize accelerator pedal opening, brake pedal opening, control pressure and the like.

It is understood that the control execution module 200 further includes a high-side driving circuit 210 and a low-side driving circuit 220, where the high-side driving circuit 210 and the low-side driving circuit 220 are connected to the main control chip, and the high-side driving circuit 210 and the low-side driving circuit 220 are respectively used for driving different components in the execution module 400.

Specifically, high side driving refers to enabling the driving device by closing the switch at the power line immediately before the electric appliance or the driving device, and low side driving refers to enabling the driving device by closing the bottom line after the electric appliance or the driving device. High-pressure interlock is a safe design method for monitoring the integrity of a high-pressure loop with a low-pressure signal, and different power domain control systems may have different high-pressure interlock implementations. More specifically, one of the risk points of high-voltage systems of electric automobiles is sudden power failure, and the automobiles lose power. There are several reasons for the possibility of losing power of the automobile, one of which is that the high-voltage loop is automatically released. The high-voltage interlocking can monitor the sign, provide alarm information for the whole vehicle controller before high-voltage power failure, and reserve the time for the whole vehicle system to take countermeasures. Another risk point of electric vehicles is manual misoperation, and in the working process of the system, the high-voltage connection point is manually disconnected. If no high-voltage interlocking design exists, the whole loop voltage is added at two ends of the break point at the moment of disconnection, and the high-voltage interlocking device is dangerous for devices which do not have breaking capacity, such as a high-voltage connector.
