Intelligent battery car online safety charging system

Abstract

The invention discloses an intelligent battery car online safety charging system which comprises more than two sets of field charging devices, wherein a single set of charging device comprises a field charging controller; a current sensor arranged in a low-voltage loop of a charging socket is connected with the controller in a 4-20mA analog signal form; a limit switch is arranged in a jack of the charging socket and is connected with the controller; a relay is arranged in the low-voltage loop of the charging socket and is connected with the controller; the controller is connected with a receipt printer in an RS485 form; controllers of all the charging devices are connected to a local area network in a centralized manner; a platform server for setting up a software platform is arranged in the local area network; the platform server is connected with an outer internet and communicates with mobile phones and computers of users; the low-voltage loop of the charging socket is used for user charging. According to the system, power can be intelligently cut off according to actual charging conditions, and a remote charging and power failure platform can be provided for the users, so that a charging loop can be automatically cut off in case that a user forgets to pull out the charger, and damage of a storage battery and accidents such as a fire are avoided.

Description

technical field [0001] The invention relates to a charging device, in particular to an online safe charging system for an intelligent battery car. Background technique [0002] With the development of society, the number of battery cars in cities is developing rapidly. At present, the charging of battery cars often causes damage to the batteries of battery cars due to the inability to grasp the time well. In serious cases, it may even cause accidents such as fires. Most of the custom delay sockets only use the method of delaying power off, which is simple, difficult to control, and cannot really realize the optimization of charging. [0003] Most of the charging of existing battery cars is to control the charging time artificially, and it is impossible to grasp the best timing of power failure. The coin-operated fast charging device is only counted by how many coins are inserted, so as to control the power-off time. Another custom delay socket also controls the charging ti...

AI Technical Summary

Problems solved by technology

The existing charging methods are not ideal. Artificial power failure is the worst way to guarantee the safety of the battery. There may be a situation of uninterrupted power supply for several days, which often leads to accidents. Coin-operated fast charging devices mostly use high current plus reverse pulse. The working principle is that it will damag...
