When charging an electric car, why does the TV interfere with snowflakes is there any solution to it

The best way to do electromagnetic interference when the transformer in the charger is working is not to charge it next to the TV.

EV charging tips.

1) Charge often.

Even if you don't have a long battery life and can last 2 to 3 days on a single charge, it is recommended that you charge it every day so that the battery is in a shallow cycle state and the battery life will be extended. Half of the electric vehicle power indication will be charged, and frequent discharge will have a greater impact on the life of the battery. Most chargers may charge the battery at 97 99 after the indicator light changes to indicate that the battery is fully charged.

Although only the power of undercharge 1 3 has almost negligible impact on the ability to continue, it will also form an undercharge accumulation, so it is also good to inhibit battery vulcanization by continuing to float charge as much as possible after the battery is fully charged and changing the lamp.

2) Charge frequently.

The vulcanization process begins after the battery is discharged, and within 12 hours, there is a noticeable vulcanization. If not charged in time, these vulcanization crystals will accumulate and gradually form coarse crystals, and the general charger is powerless against these coarse crystals, which will gradually form a decline in battery capacity and shorten the service life of the battery. Therefore, in addition to charging every day, it should also be noted that the electric vehicle should be charged as soon as possible after use, so that the battery is in a full state as much as possible.

3) Regular deep discharge.

It is also beneficial for the battery to undergo a deep discharge on a regular basis"Activation"battery, which can slightly increase the capacity of the battery. The general approach is to make a full discharge of the battery at regular intervals. The method of full discharge is to ride the bike to the first undervoltage protection under normal load conditions on a flat road.

Note that we place special emphasis on the first undervoltage protection. After the first under-voltage protection of the battery, after a period of time, the voltage of the battery will rise and return to the non-under-voltage state, at this time, if the battery is used again, the damage to the battery is great. After a full discharge, the battery is fully charged.

You will feel that the battery capacity has increased.

4) Pay attention to the charging environment.

The optimal ambient temperature for charging is 25 . Nowadays, most chargers do not have an automatic control system that adapts to the ambient temperature, so most chargers are designed according to the ambient temperature of 25, so it is better to charge under the condition of 25. Otherwise, it is inevitable that there will be problems of undercharging in winter and overcharging in summer.

The ambient temperature is really less when it is 25, so there will inevitably be the problem of overcharging in summer and undercharging in winter. Fortunately, most families now have indoor temperature control conditions, so when charging, it is best to arrange the battery and charger in a ventilated and temperature-controlled environment.

I'm an Epson Electric Vehicle Engineer. The reason is the electromagnetic interference that occurs when the transformer in the charger is working, and the best way is not to charge next to the TV.

Summary. EV charger interferes with TV solution:

1. Add a plug-in board to charge it farther away.

2. Time separation, you can't charge when watching TV, and don't watch TV when charging.

The charger is a high-frequency power supply technology, using advanced intelligent dynamic adjustment charging technology. The power frequency machine is designed based on the principle of traditional analog circuit, and the internal power devices (such as transformers, inductors, capacitors, etc.) of the machine are relatively large, and there is generally less noise when the load is large, but the model has strong resistance in the harsh power grid environmental conditions, and the reliability and stability are stronger than that of the high-frequency machine. ‍
