It may be that the battery loses a lot of power, the charging current is excessive and the heat is abnormal, and the battery is short of water in hot weather, and the heat is out of control to make the battery aging.

It may be the charger problem, the electric bicycle charging time is significantly faster or slower than the original that is the charger problem, because this will also lead to battery damage forcing the charging gas hot.

The hot charger may also be the cause of short circuit failure, which will make the battery aging or damage, it is recommended that you replace the new charger. Note: When charging, try to charge in the place where the ventilation effect is better, because if the ventilation effect is not good, the charger will be hot, you should know that the damage to the charger is great if the heat dissipation is not normal. Chargers emit a lot of heat when they charge, so most of them have fans. Maintenance method :1, visual capacitor: the more obvious feature is that the capacitor contains a certain solution, in the exceedance of the working environment, the capacitor will heat and explode to relieve the pressure that the body and mind can not bear. Resistance: After heating and overload, it will change color or smoke, of course, the resistance will also explode, explode or part of itself flies away. 2, the resistance method uses a digital multimeter to measure the suspected part of the circuit, generally use a diode file to measure, in the case of confirming that there is no plug, use tweezers to short circuit some capacitors, capacitors discharge will emit sparks and sound do not be afraid, and then the resistance value measurement. 3, substitution method substitution is to replace some devices, the replacement device may be new, or removed from a normal working charger, replacement is more suitable for specific devices such as: capacitors, integrated blocks and other devices that may be soft damage, for other hard devices, there is no need to consider replacing it.
Yes, Emma's electric car charger heats up. This is because the charger will produce a certain amount of energy loss during the working process, and the energy loss will be converted into heat energy, resulting in an increase in the surface temperature of the charger.
In order to ensure the normal operation and safe use of the charger, it is recommended that the charger should be placed in a well-ventilated position during the charging process, avoid long-term use or continuous rapid charging, in order to slow down the heat degree of the charger, and regularly check the working status of the charger, if there is an abnormal contact after-sales or maintenance personnel.
It may be because the battery and the charger do not match (voltage mismatch), the charging time is too long, the battery electrolyte is missing (internal resistance is too large, the conversion efficiency is low caused by hot), and the radiator of the charger is damaged.
At this time, the power should be unplugged and the charger should be replaced. The purchase of the charger should choose a regular manufacturer, and it is best to buy the original charger at the original after-sales point.
Emma electric car charger in the charging process will produce a certain amount of heat is a normal phenomenon. There are electronic components and transformers inside the charger, and there will be energy conversion and loss during work, resulting in certain heat. However, if the charger overheats or emits abnormal heat, it may be caused by the fault or improper use of the charger. It is recommended to stop the use in time and contact professional maintenance personnel for inspection and maintenance to ensure safe use. At the same time, the use of the charger should follow the instructions to avoid long-term continuous charging or use in a high temperature environment to reduce the risk of heat.
The main reason may be that a certain amount of heat generated when the charger is working cannot be dissipated in time. It is recommended that users pay attention to placing the charger in a well-ventilated environment and avoid long-term continuous charging.
If the charger is found to be seriously hot or abnormal, it should be stopped immediately and professional maintenance personnel should be consulted to avoid further aggravation of safety problems. In addition, it is also necessary to clean the heat dissipation hole of the charger regularly. Remember, the safe use of electric vehicle chargers is an important step to ensure the use of electric vehicles.
The answer is as follows: Emma electric car charger fever may be caused by the following reasons:
1. Charger overload: If the power supply voltage connected to the charger is too high or too many electric vehicles are connected at the same time during the use of the charger, the charger may heat up due to overload work.
2. Charger failure: If the electronic components inside the charger fail, such as short circuit board or heat sink blockage, it may cause the charger to heat up.
3. Charger aging: The charger used for a long time may cause heat due to the aging of internal components.
4. Charging environment problems: If the charger is used in a closed environment, or charged in a high temperature environment, it may also cause the charger to heat up.
If the Emma electric car charger is found to be hot, it is recommended to take the following measures:
1. Check whether the power supply voltage connected to the charger is normal to avoid too high or too low voltage.
2. Ensure that the use of the charger environment is well ventilated to avoid overheating.
3. If the charger is too hot, it is recommended to stop using it, and contact the after-sales service center or professionals of Emma electric vehicles to repair or replace the charger.
In short, the heat of the charger may be normal, but excessive heat may have security risks, and corresponding measures need to be taken in time.
I bought Emma's electric car charger at the outlet of the electric car. It may be that the charger is faulty. You can return the charger to Emma's electric car charger manufacturer for repair immediately
