Standby power supply circuit in electric vehicle battery replacing system

Abstract

The invention relates to the technical field of electric vehicle battery replacement, and particularly relates to a standby power supply circuit in an electric vehicle battery replacing system. Multi-channel power supply input, mutual switching between channels and safe isolation of the channels are realized. The technical scheme is summarized as follows: the standby power supply circuit comprisesa communication circuit, a processor circuit and a multi-channel battery isolation switching circuit. the multi-channel battery isolation switching circuit comprises a power supply output end and atleast one power supply input end, the communication circuit is connected with the processor circuit, the processor circuit is connected with the multi-channel battery isolation switching circuit, thepower output end of the multi-channel battery isolation switching circuit is used for being connected with the power supply input end of the battery replacing system, the power input ends of the multi-channel battery isolation switching circuit are used for being connected with storage batteries in a battery replacing bin of the battery replacing system in a one-to-one correspondence mode, and themulti-channel battery isolation switching circuit can switch the power input ends communicated with the power output end, and is suitable for the standby power circuit in the battery replacing systemof the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of battery replacement for electric vehicles, in particular to a backup power supply circuit in a battery replacement system for electric vehicles. Background technique [0002] With the continuous development of various express delivery related service industries, a large number of electric automatic vehicles and electric tricycles are used as transportation and transportation tools in these industries. Moreover, the electric vehicles used in these industries have a single model, high power requirements, and frequent charging. Therefore, due to actual needs in the past few years, a large number of battery replacement systems have appeared specifically for electric vehicles used in express delivery related industries. The power system is arranged according to the region. When there is a power outage in a certain area, even if all the batteries in the power swap system are fully charged, the power swap servic...

Moreover, the electric vehicles used in these industries have a single model, high power requirements, and frequent charging. Therefore, due to actual needs in the past few years, a large number of battery replacement systems have appeared specifically for electric vehicles used in express delivery related industries. The power system is arranged according to the area. When there is a power outage in a certain area, even if all the batteries in the power exchange system are fully charged, the power exchange business cannot be performed. Therefore, the backup power supply for the above power exchange system is very necessary.

[0003] The backup power supply in the prior art needs to use an independent backup battery to provide power, or use a gasoline generator or a diesel generator to provide power. The existing technical solutions all need to use an independent external backup power supply, which requires frequent maintenance, high cost, and input The source is single, the safety is not high, and it is difficult to realize the seamless switching of the backup power at the first time of power failure
