[0053] The input management module 1, the output management module 2 and the final load are connected through the input connection module 3, the output connection module 4, the internal circuit and the interface (including the wire harness cable), which is a typical series form, belongs to a single power management system, a single power supply, such as a DC / DC or battery output power supply, which can finally supply power to the load through the above-mentioned circuit. However, in actual use, such as insufficient output management module output lines or high-order intelligent driving control system requiring the use of redundant power supply, the input management module or the output management module needs to be connected in parallel more, and based on this, a parallel redundant power management system can be designed. Therefore, in some embodiments, n≥2, the input connection module 3 of the adjacent two power management units is connected correspondingly, the output connection module 4 of the adjacent two power management units is connected correspondingly, and the vehicle power management system is a multi-redundant power management system, such as Figure 13 The input management module 1, the output management module 2 and the final load are connected through the input connection module 3, the output connection module 4, the internal circuit and the interface (including the wire harness cable), which is a typical series form, belongs to a single power management system, a single power supply, such as a DC / DC or battery output power supply, which can finally supply power to the load through the above-mentioned circuit. However, in actual use, such as insufficient output management module output lines or high-order intelligent driving control system requiring the use of redundant power supply, the input management module or the output management module needs to be connected in parallel more, and based on this, a parallel redundant power management system can be designed. Therefore, in some embodiments, n≥2, the input connection module 3 of the adjacent two power management units is connected correspondingly, the output connection module 4 of the adjacent two power management units is connected correspondingly, and the vehicle power management system is a multi-redundant power management system, such as
[0054] Figure 13 There are 2 power management units, and each power management unit is composed of the same as above, and the difference is that the connection position of the jumper wire in each module is different, so as to realize different functions. The specific difference is:
[0055] The first jumper pin 19 is connected with the power input interface I 13 through a jumper, the controlled one end of the first controllable switch 17 is connected with the fourth jumper pin 112 through a jumper, the controlled other end of the first controllable switch 17 is connected with the third jumper pin 111 through a jumper, the controlled one end of the second controllable switch 18 is connected with the third jumper pin 111 through a jumper, the controlled other end of the second controllable switch 18 is connected with the second jumper pin 110 through a jumper, the fourth jumper pin 112 is connected with the redundant power interface 14 through a jumper, the fifth jumper pin 113 is connected with the cross interface 15 through a jumper, the sixth jumper pin 114 is connected with the power output interface I 16 through a jumper, the ninth jumper pin 317 is connected with the straight-through interface I 316 through a jumper, the eighth jumper pin 320 is connected with the cross connection interface II 311 through a jumper, the eleventh jumper pin 28 is connected with the power input interface II 23 through a jumper, the twelfth jumper pin 29 is connected with the redundant switch interface 24 through a jumper, the thirteenth jumper pin 416 is connected with the redundant switch connection interface II 49 through a jumper; the two communication connection interfaces II 313 are connected, the two redundant power connection interfaces II 312 are connected, the two cross connection interfaces II 311 are connected, the two communication connection interfaces VI 410 are connected, and the two redundant switch connection interfaces II 49 are connected, so as to form a dual-redundant vehicle-mounted power management system.
[0056] Figure 13The input management module 1 inputs a DC / DC power supply through an input connection interface I 31 of the input connection module 3, and inputs a battery power supply through a through interface I 316 of the input connection module 3, parallel connection of the DC / DC and the battery of each power management unit is realized, and the first controllable switch 17 and the second controllable switch 18 of the input management module 3 are controlled, the DC / DC and the battery are in parallel connection under the closed condition of the first controllable switch 17 and the second controllable switch 18, the battery can peak clipping and valley filling for the load, the DC / DC can charge the battery and simultaneously supply power for the load through the output management module 2. If the DC / DC of the first power management unit appears an overvoltage / undervoltage / overcurrent failure state, the second controllable switch 18 is disconnected, and the battery can continue to supply power to the rear end for a certain time. Similarly, the DC / DC and the battery of the second power management unit have the same function, so that the redundant power supply is designed for the two groups of loads requiring redundancy respectively. The output management module 2 connects the third controllable switch 26 for controlling the reserved redundant switch interface 24, so that the power supply of the input management module 1 of the second power management unit can enter the output management module 2 of the first power management unit, when the input management module 1 of the first power management unit fails, the DC / DC of the second power management unit can supply power for the output management module 2 and the load of the first power management unit, so that the power supply of the first power management unit is not limited to the power of the battery. Similarly, the same effect can be achieved when the input management module 1 of the second power management unit fails. The failure of the load is disconnected by the fourth controllable switch 27 of the output management module 2, and the influence on other parts of the power supply is reduced.
