Description

technical field [0001] The invention relates to a vehicle-mounted power supply, which belongs to the technical field of vehicle-mounted power supplies. Background technique [0002] In the process of power inspection, in order to ensure the efficiency and reliability of the power operation process, electric power workers usually use electronic devices such as inspection instruments and power mobile operation terminals to record the on-site conditions during the inspection process, and through electronic equipment Perform data transmission with the power background server to solve various problems in the operation process in a timely manner; then, during the above operation process, because the operation environment is mostly a wild uninhabited area, it usually occurs that the on-site data collection cannot be performed due to the low power of the electronic equipment The problem has greatly hindered the work efficiency of the operators. [0003] In order to solve the proble...

[0002] In the process of power inspection, in order to ensure the efficiency and reliability of the power operation process, electric power workers usually use electronic devices such as inspection instruments and power mobile operation terminals to record the on-site conditions during the inspection process, and through electronic equipment Perform data transmission with the power background server to solve various problems in the operation process in a timely manner; then, during the above operation process, because the operation environment is mostly a wild uninhabited area, it usually occurs that the on-site data collection cannot be performed due to the low power of the electronic equipment problems, greatly hampering the work efficiency of operators

[0003] In order to solve the problem that the electronic equipment is low in power and unable to work, power companies usually use the vehicle power supply to charge the electronic equipment. However, the current vehicle power supply is generally connected to the car cigarette lighter or battery through the power input interface of the vehicle power supply. Obtain power; the problem with this method is that in order to ensure the normal driving of the car when the voltage of the car battery is low, the power consumption of the external load device must be interrupted, making it impossible to provide power for the electronic devices that must be used during the power operation. Power supply, causing inconvenience to on-site workers
