A User's Guide to Electric Vehicle Charging

If you are an electric vehicle owner and are interested in learning about your electric vehicle charging knowledge, this guide is suitable for you! This blog will cover the charging methods and charging modes of the charging station and portable EV charger, so as to increase your understanding of electric vehicle charging knowledge, and maximize efficiency while minimizing costs!

Advantages and disadvantages of three charging methods

1. Slow charging: use a lower current to charge the vehicle power battery, and the charging time is generally more than 3 hours. The advantage of this charging method is that it has less impact on the battery life and the impact on the power grid. But this method takes a long time to charge, and the time cost is high

2. Fast charging: also known as emergency charging, the charging time is within 20 minutes to 2 hours, it saves time and effort, but it puts forward higher requirements on the voltage resistance and protection of the power battery pack, which will reduce the cycle life of the power battery pack and generally cannot be fully charged when charging. Fast charging is not suitable for medium and large electric vehicles due to the high power requirements and the relatively high cost of battery packs.

3. Battery replacement: directly replace the exhausted battery pack with a fully charged battery pack. The time required for replacement is about 10 minutes, which makes up for the shortcomings of short driving range and long charging time of electric vehicles. At the same time, users can rent storage batteries, which reduces charging costs. However, there are high requirements for the circulation management of standardized batteries, the quality of operating personnel and professional processes.

Four charging modes – MODE 1, MODE 2, MODE 3 and MODE 4

· Mode 1

There is no adapter on the charging gun. When the car is charging, it is directly plugged into the household AC socket through the cable of the charging gun for charging. Mode 1 is no longer recommended due to poor security.

· Mode 2

This is the main charging mode of portable charging guns currently on the market. The difference from mode 1 is that an adapter is added as a protection device, which not only retains the convenience of charging, but also ensures the safety and standardization of charging for new energy vehicles. Four E's Automotive offers two type of portable EV charger to meet your various demands.

· Mode 3

Mode 3 is connected to an AC charging pile. There's no adapter, but the AC charger itself does the job of protection. It can not only ensure the safety of charging, but also improve the charging speed to a certain extent. Four E's Automotive provides four type of AC charging plugs, allowing a steady and powerful current of up to 48 amps with a maximum voltage of 250 volts.

· Mode 4

The difference between mode 4 and mode 3 is that the charging gun is connected to a DC charging pile, which is generally not for household use, but is specially installed at a fast charging charging station. Mode 4 has a large charging current and the fastest charging speed. Four E's Automotive offers a wide selection of DC charging plug that is compitable with common electric vehicles, with rated current of 80A, 125A, 150A, 200A.

Mode 1 and Mode 2 are portable EV charger, they Belong to slow charging method, while Mode 3 and Mode 4 are charging stations, they're fast charging method.

Tips for charging electric vehicles:

1. When charging on rainy days, it is important to keep the interface dry to reduce the risk of electric shock.

2. When charging, it is necessary to turn off the equipment in the car. The activation of the equipment in the car increases the charge load on the on-board battery and reduces its service life.
