What are the safety protection functions of intelligent charging and swapping cabinets reflected in?

Due to the convenience of using two wheeled bicycles for travel, more and more people are choosing to use them for free travel, and as a result, charging two wheeled electric vehicles has become more common. Traditional charging methods, such as privately pulling wires for charging, do not have safety guarantees for a long time and are prone to accidents. With the development of information technology and the increasing demand for charging, smart charging and swapping cabinets have gradually entered people's vision. Smart charging and swapping cabinets can centrally charge and swap electricity, prevent charging accidents, and ensure safety. So, what are the specific aspects of the protection function of the intelligent charging and swapping cabinet?

Protection function of intelligent charging and swapping cabinet
1. Equipped with overvoltage protection, undervoltage protection, and output overvoltage protection on the input side of the power supply.
2. It has over temperature protection, and when the internal temperature reaches the protection threshold, it will reduce power or stop output.
When starting the charging process, the cabinet detects the battery voltage. When there is a misconnection or poor contact of the battery, the charging process stops and an alarm signal is issued.
Other functions
1. Charging control function. Equipped with automatic charging control function, clear operation prompt information, and the ability for personnel to debug or maintain the charging cabinet and supporting equipment under special circumstances.
2. Communication function. The charging cabinet has communication function, which determines whether each charging unit in the charging cabinet is correctly connected to the electric bicycle battery, and obtains charging parameters and real-time charging data. The charging cabinet should have the function of communicating with the higher-level monitoring system or operation management system.
3. Short circuit detection function for DC output circuit. The charging cabinet has the function of short circuit detection for the DC output circuit. The short circuit detection of the charging cabinet is carried out during the insulation detection stage. When a short circuit fault occurs in the DC output circuit, the charging process should be stopped and a background alarm prompt should be provided.
4. Human computer interaction function. Display function: Operation status indication of charging cabinet: standby, charging, and the background should have alarm prompts; Chargers with manual charging control function should display manually inputted information. The charging cabinet should display the following information: current state of charge of the battery, charging voltage, charging current, and charging power; Charged time, charged power, and charged amount. Input function: The charging cabinet should have manual input and control functions. Emergency stop function: The charging cabinet should be equipped with an emergency stop device. When the emergency stop device is activated, the charging cabinet should simultaneously cut off the power input and DC output.
These protective functions enhance the safety of intelligent charging and swapping cabinets, avoid charging hazards, and provide a guarantee for the safe use of electricity by car owners.
