Is your electric charger safe? Do you know how to choose a safe charger?

At the peak of each traffic jam, there will always be a group of electric car teams unimpeded, all the way green light, suddenly gave birth to inexplicable envy, 

Although the electric car is very convenient, charging is a very important part. The choice of charger is also required. Let's see. Did you get it right?

1. Determine battery capacity and output current

First determine the battery capacity of the electric car battery AH, or the output current of the original charger. Look at the original charger judging capacity: the original charger output current is 1.8 A of the indicated battery is 12 AH.

Second, look at the battery voltage: The batteries in the general battery box have written models, such as 6-DZM-12, 12 indicates that it is a 12AH battery, 6-DZM-20, and 20 indicates that it is a 20AH battery.

The third is based on the mileage of a charging run: In general, a battery of about one year, full of 25-40 kilometers at a time, 12AH charger is more suitable. Run 45-60 kilometers, 20AH's more appropriate.

2. Determine Charger Positive and Negative

Determine suitable for electric vehicle charger interface shape positive and negative pole. The more common interfaces in the market are T-type product prefixes, three vertical product prefixes, and round heads. Some character plugs may be positive or negative.

You can take the multimeter electric vehicle battery charging interface to find out the positive and negative poles. The charger output purchased is consistent with the charging socket. The negative pole of the charger will damage the charger and the battery.

3. Determine charger quality

A good electric vehicle charger adopts positive and negative pulse technology, which can effectively prevent, suppress, and eliminate the vulcanization and polarization of the battery. The new battery capacity can be kept stable for a long time; The old battery capacity that has been polarized and its capacity has been reduced has been restored, and the useful life of the battery has been effectively extended by 2 to 3 times. It has intelligent timing protection function, automatic temperature compensation function, instantaneous impact protection of the power grid, Super moisture prevention and corrosion prevention function.

4. Choose a brand

In general, there are four reasons for battery damage: water loss, vulcanization, imbalance, and thermal runaway(filling). We must choose products with great brand reputation and a good reputation. Many inferior chargers on the market are very easy to produce overcharge, undercharge, water loss, vulcanization, and other phenomena. It is a great danger to consumers 'personal and property safety.

Large brand charger products have designed a lot of charging protection functions, greatly increase the safety and efficiency of charging.

Charger choice is good, charging time is also need to pay attention to ha, must find a special place to provide electric car charging, but do not buy a socket to charge Ha, so the security system is not guaranteed.
