[0028] The controller is a master device for starting, speed regulation, braking and reversing of the motor. The controller mainly includes a filter assembly, a capacitor and an IGBT module, which cooperate with each other to convert the direct current of the battery into alternating current and transmit it to the motor. However, in the existing controller, two copper bars are usually needed to be arranged between the fast charging bus and the filter assembly to transmit positive and negative electric signals, and two copper bars are also needed to be arranged between the filter assembly and the IGBT module to transmit positive and negative electric signals, which occupies more space in the controller.
[0029] To solve the above technical problems, the present application provides a controller, as shown in Figures 1 to 3 The controller includes a filter assembly 10, a fast charging bus 30 and a capacitor 40. The fast charging bus 30 includes a fast charging negative bus 32. The capacitor 40 includes an insulating shell 41, a negative copper bar 42, a first terminal 43 and a second terminal 44. The negative copper bar 42 is arranged in the insulating shell 41. The first terminal 43 and the second terminal 44 are electrically connected to both sides of the negative copper bar 42, and extend out of the insulating shell 41. The first terminal 43 is connected to the fast charging negative bus 32, and the second terminal 44 is connected to the negative electrode of the filter assembly 10. On the one hand, when charging, the negative electric signal is transmitted to the battery through the fast charging negative bus 32, the first terminal 43, the negative copper bar 42, the second terminal 44 and the negative electrode of the filter assembly 10 in sequence. On the other hand, when discharging, the negative electric signal is transmitted to the IGBT module 70 through the battery, the filter assembly 10, the second terminal 44 and the negative copper bar 42 in sequence. Thus, the negative copper bar 42 arranged in the insulating shell 41 plays a protective and insulating role for the negative copper bar 42. The first terminal 43 and the second terminal 44 are electrically connected to both sides of the negative copper bar 42 and extend out of the insulating shell 41. The first terminal 43 is connected to the fast charging negative bus 32, and the second terminal 44 is connected to the negative electrode of the filter assembly 10. The negative copper bar arranged outside the capacitor 40 in the prior art is reused as the negative copper bar 42 in the insulating shell 41 of the capacitor 40, so that the filter assembly 10 and the IGBT module 70 can reuse the negative copper bar 42 in the capacitor 40 to transmit the negative electric signal, thereby reducing the number of negative copper bars 42, increasing the integration of the controller, and saving the space inside the controller.
[0030] In some embodiments, referring to Figure 1 and Figure 2As shown, the controller further comprises a first positive copper bar 20; the fast charging bus 30 further comprises a fast charging positive bus 31; the capacitor 40 further comprises a third terminal 45, the third terminal 45 is arranged outside the insulating shell 41, the third terminal 45 is connected to the fast charging positive bus 31 and the first positive copper bar 20 at the same time, and the side of the first positive copper bar 20 away from the fast charging positive bus 31 is connected to the positive electrode of the filter assembly 10.

During charging, the positive electrode signal is transmitted to the battery through the fast charging positive bus 31, the first positive copper bar 20 and the filter assembly 10 in turn. Such a design saves the space for arranging the terminal on other structural members due to the integration of the third terminal 45 on the shell, and the first positive copper bar 20 and the fast charging positive bus 31 are well supported.
[0031] In some embodiments, referring to Figures 1 to 3 As shown, the capacitor 40 further comprises a second positive copper bar 46, the second positive copper bar 46 is arranged inside the insulating shell 41, and the second positive copper bar 46 is arranged in insulation with the negative copper bar 42. In this way, the second positive copper bar 46 transmits the positive electrode signal in the capacitor 40. Specifically, the capacitor 40 further comprises a fourth terminal 47, the fourth terminal 47 extends outside the insulating shell 41, the fourth terminal 47 is connected to the second positive copper bar 46, and the fourth terminal 47 is connected to the positive electrode of the filter assembly 10. The fourth terminal 47 is integrated on the insulating shell 41, and the second positive copper bar 46 and the positive electrode of the filter assembly 10 can be electrically connected through the fourth terminal 47. During discharging, the positive electrode signal is transmitted to the IGBT module 70 through the battery, the filter assembly 10 and the second positive copper bar 46 in turn. Such a design can discharge through the second positive copper bar 46 inside the capacitor 40 due to the integration of the fourth terminal 47 on the shell.

The fourth terminal 47 can simultaneously transmit the positive electrode signal during charging and the negative electrode signal during discharging. Since the charging and discharging of the vehicle are alternately performed, i.e., the vehicle stops discharging when charging and stops charging when discharging, the positive electrode signal during charging is transmitted to the battery in sequence through the fast-charging positive bus 31, the first positive copper bar 20, the first relay terminal 51, the second relay terminal 52, the filtered positive copper bar 60, and the filter assembly 10, and the positive electrode signal during discharging is transmitted to the IGBT module 70 in sequence through the battery, the filter assembly 10, the filtered positive copper bar 60, the fourth terminal 47, and the second positive copper bar 46.

Thus, the partition plate 401 and the insulating shell 41 can be formed into an integral structure through a process such as injection molding, the partition plate 401 being located between each positive output terminal 48 and each negative output terminal 49, which can reduce the electrical signal interference between the positive output terminal 48 and the negative output terminal 49, and can also reduce the risk of positive and negative short circuit.
