Yes: 1. Positive port: Connects the positive terminal of a battery. 2. Negative interface: The interface connecting the negative electrode of the battery; 3. Control contact: the contact that controls the battery charging state; 4. Detail interface: It is generally a data transmission or heating control interface, which varies according to different brands and models of slow charging guns.
The charging principle of the slow charger is: by controlling the charging current and voltage, the battery is charged slowly and safely.
When charging, the positive and negative terminals contact the positive and negative terminals of the battery respectively, and the control contact achieves the control and monitoring of the charging state through the internal control chip. The detail interface is generally used to control the detailed parameters during the charging process, such as protecting the battery from overheating and short circuit. It should be noted that the interface of different brands and models of slow charging guns may not be exactly the same, and it is best to consult the relevant manufacturer or dealer before purchase to obtain detailed interface information.
1. Positive and negative level lines (\/-) are used to connect the power supply, positive level lines are connected to the positive terminal, negative level lines are connected to the negative terminal; 2. CAN line, used to transmit the communication signal between the charger and the electric vehicle, to ensure the safety and stability of charging; 3. The temperature sensor line is used to detect the battery temperature and return the charger by transmitting data in order to control the size of the charging current; 4. Control line, responsible for controlling the switch of the slow charging gun, fault detection and fault tolerance processing and other functions.
The above four pins are the basic definition of the slow charge gun, and they work together to achieve the charging function of the electric vehicle.
At the same time, in practical applications, there are some other pin definitions that vary according to different charging needs.
For example, for charging stations with fast charging functions, it is also necessary to define separate fast charging lines for the transmission of higher power.
Each pin of the recharging gun is defined.
Slow charge gun refers to a gun-shaped charger used for charging.
The number of pins and the definition are different from other chargers, because the definition of the pin of a slow charge gun may vary from manufacturer to manufacturer. Generally speaking, the slow charge gun has AC power plug (AC), power FUSE (FUSE), control signal line (CP), DC power line (DC, DC-) and other pins. The charging speed of slow charging gun is slower than that of fast charging gun, but the charging safety is higher, and the charging cost is generally cheaper, so in some occasions where charging time is sufficient, slow charging gun is widely used in electric vehicle charging and other fields.
Believe refers to the definition of the various ports of the electric vehicle slow charge gun.
Slow charge gun is usually the use of J1772 international standard connector, its specific definition is as follows: 1. L1 phase pin: used to transmit single-phase power voltage level; 2. L2 phase pin: same as above; 3. L3 phase pin: same as above; 4. PP pin: used for grounding of transmission power; 5. CP pin: used to transmit the start signal (CP pin and PP pin short, slow charging gun will start to work); 6. CP PE pin: Used to transmit fault signals (if the fast charge device fails, the CP PE pin is raised).
By the above pin definition, the slow charge gun can achieve effective power transmission and fault signal transmission.
