At present, electric vehicle coin-operated charging stations are very popular in cities, especially electric vehicle repair shops, and convenience stores are more widely used. However, there is no formal after-sales system for coin-operated charging stations. If the machine is broken, it will be handled by the factory, or the equipment will be repurchased, which is time-consuming and expensive. It has added a lot of costs to users, so today Xiaogang will tell you about the common faults and solutions of coin-operated charging stations.
The common problems and solutions of the charging station are as follows
One, the charging station cannot accept coins
Two, the charging station is plugged in The electric vehicle has no voltage
3. The display of the charging station does not light up
4. The connecting wire of the charging station is disconnected
5. The charging station cannot be charged

Six, the voice of the charging station is indiscriminate
One, the charging station cannot accept coins into two phenomena
1. Plug in the electric car If there is voltage and there is a voice prompt, please insert the coin. If there is voltage and the coin cannot be inserted, generally the coin-operator itself is faulty, there is dirt in the coin-operator, and there is a gap in the middle of the coin-operator. The service switch is out of order, or a factory reset is required.
2. There is no voltage and no voice prompt when plugged in the electric vehicle, and there is no voltage when the electric vehicle is plugged in, and the coin cannot be put in. This problem is usually caused by a circuit failure. Because the premise of the coin-operated coin is to have a voice prompt and display the voltage of the electric vehicle. Please see “2” below for this question.
Second, the charging station is plugged into the electric vehicle without voltage
1, first check that the plug of the charging cable has There is no bad contact or disconnection. If there is no multimeter measurement, you can change a new line, or you can switch the charging line left and right to find out the fault.
2. Check whether the output fuse of the motherboard is disconnected (some motherboards do not need this operation if they do not use output fuses).
3. The main board relay is burnt. Generally, except for the wire and the fuse, the relay is the most easily damaged component. The machine vibrates, falls, and the non-stop charging for a long time will cause the relay to be damaged, or the contacts will stick and burn. Bad fuse. If the relay is burned out, it is usually returned to the company for processing. If the wire and fuse are damaged, the user can solve it by himself without returning to the factory.
Third, the screen of the charging station does not light up, common problems and solutions
1. Check the power cord first, if the screens on both sides are not bright , you can check whether the power cord of the socket and the charging station is disconnected. If one side does not light up, it can prove that the socket and power cord are good.
2, and then check the motherboard, you can first check the power fuse, whether there is black burning, such as burning black, it proves that there is a short circuit in the switching power supply of the motherboard , To return to the company, if the fuse has no black burn marks, but the black wire is broken, you can replace the fuse of the same type and try the machine again.
3, the display board problem, if the main board has power, the display light is not On, you can use the swap method to determine where the problem is, and replace the good display board with the bad display board to test the machine. If the display light will be on at this time, it proves that the original display board is broken. Prove that the original motherboard is broken. Bad parts can be returned to the factory after a problem is diagnosed.
4. Warm reminder, the display does not light up after the new machine is received, usually it is oscillated or dropped on the courier road, causing the motherboard to vibrate and disconnect or desolder.
Fourth, the connecting wire of the charging station falls off
1. The connecting wire connecting the battery is broken, and the local contact is poor, usually in the plug It is easier to break at the branch or at the branch port, you can change the plug again, or try the whole line again.
2. If there is a problem with the main board, please check whether the wiring terminals of the main board are tightened, and see if the fuse is loose. You can tighten or replace a fuse, and try the machine again. If the above has been replaced or not, it is the main board circuit. The problem needs to be returned to the factory for repair.
3. If the connection line occasionally falls off, it is due to the serious undervoltage of the guest’s electric vehicle battery. It is normal for the cable to fall off when no power is supplied.
Fifth, the charging station cannot be charged
1. If the coin is normal, the time can be completed normally, except that the line contact may not be good. In addition, it is usually the motherboard problem. During the charging process, press the “Inquiry” button to see if there is a current number. If the display shows “A0.00”, it means that the motherboard is broken, please return to the factory for repair.
Six, the voice of the charging station is indiscriminately reported
1, the speaker problem, the two positive and negative electrodes of the speaker touch the chassis, resulting in leakage If the voice is noisy, you can take out the speaker and adjust the position so that the contacts do not touch the chassis iron case.
2. There is a problem with the voice board. If the speaker is normal and it still screams, please check first whether the connection line between the main board and the voice board is loose. You can re-clamp it and insert it back into the test machine. The left and right display boards, for the debugging machine, if they have been exchanged, the ones that are screaming will not be called, which proves that the voice board is broken. If it still screams, it proves that the motherboard is broken, and the bad parts can be sent to the factory. Generally, the probability of the motherboard being broken is very rare. Basically, the voice display board is broken. Dear parents, please check carefully.
