[0014] The compressor device of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] See also Figure 1 , Figure 1A schematic diagram of the first embodiment of the compressor device provided in this application. In this embodiment, the compressor device includes a compressor motor and a drive module, the compressor motor includes a motor coil, the drive module includes a drive bridge arm, the motor coil is connected to the drive bridge arm, the drive bridge arm and the motor coil are both connected to the external charging port, the drive bridge arm is connected to the external battery, and the motor coil is connected to the external energy storage isolation module. The compressor device is arranged on the vehicle, and when the vehicle needs to be charged, the compression and device of the vehicle are connected to the external charging port on the charging pile, and the external energy storage isolation module is used to isolate the charging pile from the vehicle. The compressor controller is used to obtain the first instruction and meet the first preset condition, the compressor controller performs the first mode function, the external battery, the drive bridge arm and the motor coil form a charging circuit to charge the external energy storage isolation module, and the external energy storage isolation module voltage is adapted to the external charging port voltage to achieve the handshake between the vehicle and the charging pile. The compressor controller is used to obtain the second instruction and meet the second preset condition, the compressor controller performs the second mode function, the external charging port, the motor coil and the drive bridge arm form a DC charging circuit to charge the external battery. When the vehicle's air-conditioning system requires the compressor device to work, the compressor controller is used to obtain a third instruction and when a third preset condition is met, the compressor controller executes a third mode function, and the external battery, the drive bridge arm and the motor coil form a motor drive circuit to drive the compressor motor of the compressor device.

[0016] The motor coil of the compressor device of this embodiment is connected to the driving bridge arm, and the external battery, the driving bridge arm and the motor coil form a charging circuit to charge the external energy storage isolation module, which has a first mode function; the external charging port, the motor coil and the driving bridge arm form a DC charging circuit to charge the external battery, which has a second mode function; the external battery, the driving bridge arm and the motor coil form a motor driving circuit, which has a third mode function. This embodiment can meet the complex working conditions of the vehicle by adding the compressor device function.

[0017] In the second embodiment, please refer to Figure 2 , Figure 2The schematic diagram of the second embodiment of the compressor device provided for the present application is based on the first embodiment, and the motor coil is connected to the external charging port through the switch module, and the motor coil is connected to the external energy storage isolation module through the switch module. When the vehicle needs to be charged, the compressor controller performs the first mode function, and the controller controls the switch module to connect the motor coil with the external energy storage isolation module. The external battery, the drive bridge arm and the motor coil form a charging circuit to charge the external energy storage isolation module. The voltage of the external energy storage isolation module is adapted to the voltage of the external charging port to achieve handshake between the vehicle and the charging pile. The compressor controller is used to execute the second mode function when the second instruction is obtained and the second preset condition is met. The compressor controller controls the switch module to connect the motor coil with the external charging port. The external charging port, the motor coil and the drive bridge arm form a DC charging circuit to charge the external battery.

[0018] In the third embodiment, based on the first embodiment, when the compressor controller is used to obtain the first instruction and the temperature is less than the preset temperature value, the compressor controller executes the first mode function, and the external battery, the drive bridge arm and the motor coil charge the external energy storage isolation module, so that the voltage value U1 of the external energy storage isolation module is equal to U2, and U2 is the target voltage value of the external energy storage isolation module, so as to adapt to the voltage of the external charging port, and avoid the external battery voltage in the vehicle from being damaged due to the large voltage difference with the charging pile. The first instruction can be a compressor charging handshake instruction, the temperature less than the preset temperature value can be the ambient temperature less than the preset value or the external battery temperature less than the preset value, and the target voltage value U2 can be a voltage value preset according to the external charging port.

[0019] In the fourth embodiment, based on the third embodiment, after the vehicle shakes hands with the charging pile, the compressor controller obtains the second instruction, the compressor device function self-check is normal and U1=U2, U1=U2 indicates that the vehicle and the charging pile have successfully shaken hands, the compressor device function self-check is normal, indicating that the compressor device can be used to perform the charging function, the compressor device function self-check is used to ensure the safety of the compressor device, and the second instruction can be a compressor charging instruction. When the second instruction is obtained, the compressor device function self-check is normal and U1=U2, and all three conditions are met, the compressor controller executes the second mode function, and multi-condition judgment improves the safety of the compressor device charging the external battery, while expanding the function of the compressor device, ensuring the safety of the compression device.

[0020] In the fifth embodiment, on the basis of the fourth embodiment, the compressor controller obtains the external charging port voltage U5, the voltage value U1 of the external energy storage isolation module and the voltage U5 of the external charging port. The voltage difference U6: U6 = U1-U5, when the compressor controller obtains U6 < a4, a4 ​​is the fourth preset value, and the compressor controller controls the drive bridge arm to work to charge the external battery. The voltage difference U6 < a4 between the voltage value U1 of the external energy storage isolation module and the voltage U5 of the external charging port avoids excessive pressure difference between the voltage value U1 of the external energy storage isolation module and the voltage U5 of the external charging port, avoids the voltage difference between the voltage value U1 of the external energy storage isolation module and the voltage U5 of the external charging port from being controlled within a reasonable range, avoids damage to the external energy storage isolation module, and also avoids the compressor controller from frequently controlling the drive bridge arm to adjust the voltage of the external energy storage isolation module.

[0021] In the sixth embodiment, on the basis of the fourth embodiment, the compressor controller is also used to obtain the pressure difference U4 between the target voltage value U2 and the current battery voltage U3: U4=U2-U3, when a1≦U4≤a2, the compressor controller controls the drive bridge arm to work so that the voltage value U1 of the energy storage isolation device is lower than the battery voltage U3, a1 is the first preset value, and a2 is the second preset value. For example, U1=U3-a3, a3 is the third preset value. a1, a2 and a3 can be set according to actual needs. When U4<a1, the compressor controller controls the drive bridge arm to work so that the voltage value U1 of the energy storage isolation device adapts to the external charging port voltage U5, for example: U1=U2. When U4>a2, the compressor controller controls the drive bridge arm to work so that the voltage value U1 of the energy storage isolation device adapts to the external battery voltage U3, for example: U1=U3. During the process of charging the external battery, the voltage of the external battery and the external energy storage isolation module is obtained in real time, and the voltage of the external energy storage isolation module is adjusted in real time to balance the voltage difference between the external charging port and the external battery to avoid damage to the external energy storage isolation module.

[0022] In the seventh embodiment, on the basis of the fifth embodiment, the vehicle is connected to the charging pile, and when the vehicle shakes hands with the charging pile, the compressor controller performs the first mode function, and the external battery, the driving bridge arm and the motor coil form a charging circuit to charge the external energy storage isolation module. At this time, the compressor controller increases the duty cycle of the driving bridge arm to the first duty cycle within the preset time. The first duty cycle can be the duty cycle of the driving bridge arm required for the external energy storage isolation module to reach the target voltage value. The first duty cycle can also be the duty cycle of the driving bridge arm required for the voltage value U1 of the energy storage isolation device. Increase the duty cycle of the driving bridge arm to the first duty cycle within the preset time to avoid damage to the driving bridge arm of the compression device due to the sudden increase in the duty cycle of the driving bridge arm. The compressor controller controls the driving bridge arm to work at a switching frequency of 10-30K. This switching frequency can make the charging current fluctuation and ripple current of the charging circuit formed by the external battery, the driving bridge arm and the motor coil small, thereby improving the stability of charging.

[0023] In the eighth embodiment, on the basis of the first embodiment, when the compressor controller obtains the third instruction and the parameter of the motor coil is less than the preset value, the compressor controller executes the third mode function, and the external battery, the drive bridge arm and the motor coil form a motor drive circuit. The compressor controller matches different drive bridge arms and motor coil parameters when executing different mode functions. The compressor controller executes the first mode function, the parameters of the drive bridge arm and the motor coil are within the first preset parameter range, the compressor controller executes the second mode function, the parameters of the drive bridge arm and the motor coil are within the second preset parameter range, the compressor controller executes the third mode function, the parameters of the drive bridge arm and the motor coil are within the third preset parameter range, and the compressor controller executes the fourth mode function, the parameters of the drive bridge arm and the motor coil are within the fourth preset parameter range. The parameters of the drive bridge arm and the motor coil may include bus current voltage and motor coil VUW three-phase voltage. For example, after the compressor controller controls the drive bridge arm and the motor coil to execute the second mode function, the compressor controller controls the drive bridge arm and the motor coil to execute the third mode function, and it is necessary to detect whether the drive bridge arm and the motor coil match the corresponding parameters, that is, whether the parameters of the drive bridge arm and the motor coil are within the corresponding parameter range. The compressor controller performs different mode functions, driving the bridge arm and the motor coil to match the corresponding parameters, while expanding the compressor device and ensuring the performance and safety of the compressor device.

[0024] In the eighth embodiment, on the basis of the first embodiment, the compressor controller is further used to obtain a fourth instruction and when a fourth preset condition is met, the compressor controller executes a fourth mode function, and the motor coil, the drive bridge arm, the external energy storage isolation module and the external battery form a heating circuit to heat the external battery. The compressor controller is also used to obtain a fourth instruction and when a fourth preset condition is met, the compressor controller executes a fourth mode function, and the external battery, the drive bridge arm and the motor coil form a charging circuit to charge the external energy storage isolation module, and the external energy storage isolation module, the motor coil and the drive bridge arm form a heating circuit to heat the external battery. The heating of the external battery by the water heater is replaced by the heating of the external battery by the charging and discharging of the external energy storage isolation module, thereby reducing costs and weight.

[0025] In one embodiment, see Figure 3 , Figure 3 A schematic diagram of a third embodiment of a compressor device provided in the present application. The driving bridge arm 11 includes: a three-phase bridge arm formed by a first driving switch unit (Q1) and a second driving switch unit (Q2) connected in series, a third driving switch unit (Q3) and a fourth driving switch unit (Q4) connected in series, and a fifth driving switch unit (Q5) and a sixth driving switch unit (Q6) connected in series; the first end of the first driving switch unit (Q1), the first end of the third driving switch unit (Q3), and the first end of the fifth driving switch unit (Q5) are connected in series to form the positive end of the driving bridge arm 11, and the positive end of the driving bridge arm 11 is connected to the positive end of the battery 2; the second end of the second driving switch unit (Q2) is connected to the positive end of the fourth driving switch unit (Q4). The second end of the first drive switch unit (Q4) and the second end of the sixth drive switch unit (Q6) are connected together to form the negative end of the drive bridge arm 11, and the negative end of the drive bridge arm 11 is connected to the negative end of the battery 2; the connection point between the second end of the first drive switch unit (Q1) and the first end of the second drive switch unit (Q2) is connected to the first phase coil of the motor coil, the connection point between the second end of the third drive switch unit (Q3) and the first end of the fourth drive switch unit (Q4) is connected to the second phase coil of the motor coil, and the connection point between the second end of the fifth drive switch unit (Q5) and the first end of the sixth drive switch unit (Q6) is connected to the third phase coil of the motor coil.

[0026] Principle of boosting charging from charging pile to vehicle: see Figure 3, the driving bridge arm 11, the motor coil 41 and the external charging port form a first DC charging circuit to charge the external battery. Taking a group of upper and lower bridge arms, upper bridge Q1 and lower bridge Q2 as an example, during boost charging, Q1 is closed, Q2 is turned on, and the current of the charging port passes through the coil to Q2. Q2 is turned off, and the current of the first phase coil decays. At this time, Q2 is turned on, and the inductive reactance of the first phase coil boosts the current, and the current flows to battery 2 to charge battery 2. That is, during the boost charging process, a group of upper and lower bridge arms, upper bridge Q1, lower bridge Q2 and the first phase coil form a boost module to boost the charging port current to complete the external battery charging. During boost charging, multiple groups of upper and lower bridge arms and corresponding motor coils can form a boost module to boost the charging port current.

[0027] Battery heating principle: see Figure 3 , taking a set of upper bridge Q1 and lower bridge Q2 as an example, Q1 is turned on, Q2 is turned off, and battery 2 charges the external energy storage isolation module 3 through Q1 and the first coil. After the external energy storage isolation module is charged, Q2 is turned on, Q1 is turned off, and the external energy storage isolation module is discharged. At this time, Q1 is turned on, Q2 is turned off, and the first phase coil inductive reactance increases the discharge voltage of the external energy storage isolation module, and the current flows into the battery 2 module. Since battery 2 has internal resistance, when a large current flows in, the internal resistance heats up, and battery 2 heats up. Multiple sets of upper and lower bridge arms and corresponding motor coils can form a heating circuit to heat the external battery.

[0028] External energy storage isolation module charging principle; see Figure 3 Taking a set of upper and lower bridge arms, upper bridge Q1 and lower bridge Q2, as an example, Q1 is turned on, Q2 is turned off, and the battery 2 charges the external energy storage isolation module 3 through Q1 and the first coil. Multiple sets of upper and lower bridge arms and corresponding motor coils can form a charging circuit to charge the external energy storage isolation module.
