[0043] The electric vehicle market is currently experiencing rapid development, and the demand for charging power has also increased significantly. The power of charging piles on the market is becoming increasingly higher, and most use air cooling. However, due to the low efficiency of air cooling, it is unable to effectively reduce the internal temperature of the charging pile. Therefore, technologies such as liquid-cooled integrated cabinets and liquid-cooled integrated charging piles have been proposed. However, in situations where charging demand is high, ordinary integrated charging piles are unable to meet multiple charging power requirements simultaneously. Therefore, this application proposes a charging control device that effectively solves the problem of ordinary integrated charging piles being unable to meet multiple charging power requirements and further improves charging efficiency.

[0044] Example 1

[0045] Figure 1 A schematic diagram of a charging control device according to an embodiment of the present invention. The charging control device includes a power compartment 100 and at least one charging gun 130. The power compartment 100 includes at least one charging module 110 and a charging control module 120. The charging module 110 includes at least one charging unit 111, at least one adjustment unit 112, and at least one driver board 113. Each adjustment unit 112 is connected to a corresponding charging unit 111 and a driver board 113, and each charging unit 111 is in communication with each other. Each driver board 113 is also connected to the charging control module 120. The charging control module 120 is also connected to each charging gun 130.

[0046] Among them, such as Figure 2 As shown, the adjustment unit 112 includes a positive matrix board and a negative matrix board. Each charging module 110 is connected to the corresponding positive matrix board and negative matrix board, respectively. The positive matrix board is also connected to the corresponding driver board 113. The number of positive matrix boards connected to each driver board 113 is less than or equal to a preset number. The positive matrix board includes a relay. The driver board 113 is electrically connected to the relay within the positive matrix board. The preset maximum number of positive matrix boards connected to the driver board is determined by the signal output capability of the driver board.

[0047] In this embodiment, each charging unit 111 is sorted according to the logical address and is connected to the positive matrix board and the negative matrix board respectively. The driving board 113 is also connected to the corresponding positive matrix board. The number of positive matrix boards connected to the driving board 113 must be less than or equal to 4. That is, the number of positive matrix boards connected to the driving board 113 can be any number of 1, 2, 3 and 4.

[0048] The specific number of charging units 111 is determined by the granularity of the charging units 111 and the power of the power bin 100. The number of matrix boards and driver boards 113 is determined by the charging units 111. For example, if the granularity of the charging units 111 is 40kW and the power of the power bin 100 is 960kW, the number of charging units 111 is the power of the power bin 100 divided by the granularity of the charging units 111, which is 24. Therefore, the number of charging units 111 is set to 24. Each charging unit 111 is connected to one positive matrix board and one negative matrix board, so 24 positive matrix boards and 24 negative matrix boards are required. Since the driver boards 113 can connect to a maximum of four positive matrix boards, a minimum of six driver boards 113 are required. It should be noted that the power of the power bin 100 should be between 480kW and 1440kW, and the granularity of the charging units 111 should be ≤80kW. In other embodiments, the power of the power bin 100 and the granularity of the charging unit 111 may select other power values, which are not limited in this application.

[0049] It should be noted that when an electric vehicle is connected to a charging gun 130, the charging control module 120 obtains the charging pile's charging power data through the charging gun 130 and further selects a corresponding power allocation strategy based on the charging power data. To achieve power allocation, at least one charging unit 111 is connected to the charging gun 130 to output power. When allocating power, the driver board 113 controls the relays on the matrix board to connect the charging gun 130 to the corresponding charging unit 111, thereby meeting the charging needs of the charging gun 130 and achieving power allocation.

[0050] It is further explained that if the corresponding charging unit 111 still cannot meet the power demand after being called, the driver board 113 will control the closing of the remaining matrix board relays and call the remaining charging modules 110 connected to the charging control module 120 topology to achieve power distribution.

[0051] Optional, such as Figure 3 As shown, the device also includes: at least one liquid cooling and heat dissipation module 140; each liquid cooling and heat dissipation module 140 is connected to the charging control module 120; each liquid cooling and heat dissipation module 140 is connected to each charging gun 130 in a one-to-one correspondence. The liquid cooling and heat dissipation module 140 includes: a coolant tank, a hydraulic pump, a cooling pipe, and a radiator; the coolant tank is connected to the hydraulic pump via a pipe; the hydraulic pump is connected to the radiator via the cooling pipe; and the hydraulic pump is also connected to the charging control module 120.

[0052] It should be noted that the charging gun 130 will experience derating if operated at high current for extended periods. Therefore, a liquid cooling module 140 is required to maintain constant power output from the charging gun 130. The liquid cooling module 140 removes heat by circulating coolant through the system. Coolant has a higher specific heat capacity and can absorb more heat with a smaller temperature rise than air. When the charging control module 120 and charging gun 130 generate heat during operation, the coolant effectively absorbs the heat, maintaining their temperatures within a reasonable range and preventing overheating.

[0053] By providing the liquid cooling module 140 , the risk of accidents such as fire is reduced, the safety of the charging process is guaranteed, and the charging gun 130 is ensured not to be affected by the temperature, thereby further increasing the charging efficiency.

[0054] Optionally, the device further includes: an auxiliary power supply module 150; the auxiliary power supply module 150 is electrically connected to each of the driving boards 113, the charging control module 120, the liquid cooling module 140 and each of the charging guns 130 respectively.

[0055] The auxiliary power supply is a 12V or 24V power supply, providing control power to the driving board 113 , the charging control module 120 , the liquid cooling module 140 and each of the charging guns 130 .

[0056] Optionally, the charging control module 120 includes: a main control unit; the main control unit is connected to each of the driving boards 113 and each of the charging guns 130, respectively, and the driving board 113 controls the corresponding adjustment unit 112 according to the main control signal to charge each of the charging guns 130 respectively.

[0057] The charging control module 120 further includes: a business unit, a touch screen and a sensor; the main control unit is communicatively connected to the business unit, the touch screen and the sensor respectively; the main control unit is also connected to the liquid cooling module 140.

[0058] It should be noted that the charging control module 120 obtains the charging power information of each charging gun 130 through the main control unit, sends a main control signal to the driver board 113 based on the charging power information, monitors the voltage value or other charging information of the charging gun 130 through sensors, and uploads the charging information to the business unit, which records and analyzes the data. The touch screen displays the operating status information of the charging pile in real time, enabling user interaction with the charging device. The charging control module 120 also includes fault feedback functions such as insulation monitoring, access control feedback, water immersion alarm, gun seat feedback, and emergency stop feedback.

[0059] As a further technical solution of this application, Figure 4 As shown, Figure 4 Figure 1 is the electrical topology diagram of the charging control device. It obtains power from the grid and transmits it to the power compartment 100 through protective devices such as a lightning arrester 400, an AC contactor 600, a molded case circuit breaker 500, and a residual current circuit breaker 300. The power compartment 100 converts the AC power input from the grid into DC power and provides control power to the charging control module 120, the charging module 110, and the liquid cooling module 140 via the auxiliary power module 150. The charging control module 120 controls the charging module 110 to allocate charging power to the charging gun 130 based on the charging power data from the charging gun 130. Simultaneously, the charging control module 120 controls the liquid cooling module 140 to replenish coolant to the charging gun 130 to achieve a temperature control effect.

[0060] Among them, the lightning arrester 400 is used to prevent the charging pile and electric vehicles from being damaged by lightning, the leakage circuit breaker 300 is used to quickly detect the leakage of the internal circuit of the charging pile or the charging vehicle, and cut off the power supply in time to prevent overcurrent damage, the molded case circuit breaker 500 is used for circuit on-off control and short-circuit protection, the AC contactor 600 is used to control the on-off of the module, and the high-voltage DC contactor 200 is used for circuit control to further achieve safety protection for the circuit.

[0061] This embodiment obtains the total charging power and charging demand required by each charging gun through the charging control unit, schedules and manages the charging power through the charging control module, and allocates power to different charging guns for charging according to the charging demand, thereby realizing the function of a super charging all-in-one machine, reducing manufacturing costs, and improving the flexibility of power allocation.
