4 charging modes of electric car

4  modes of EV charger introduction: 

1. Mode 1

There is no adapter (or named control EV box,) on the charging cable. When the car is charging, it is directly plugged into the household AC socket through the cable of the charging cable for charging, and communication with the vehicle cannot be established. The maximum current strength and voltage cannot be confirmed during charging. The charging method of Mode 1 has basically been eliminated due to poor safety.

2. Mode 2

The main charging mode of portable EV charger currently on the market. The difference from mode 1 is  a protective device, an adapter is added. At the same time, communication is established with the vehicle through the control cable, and charging parameters can be exchanged between the vehicle and the charger. Portable EV charger generally adopts this mode, and the charging current is small,generally 8-16A.

3. Mode 3

The difference between Mode 3 and Mode 1 or 2 is that the charging plug is not connected to the household AC power grid, it is connected to a dedicated AC power supply device, that is, an AC charging pile. At this time, the charging plug can have no adapter, because the AC charging pile itself plays a protective role. Mode 3 can not only ensure the safety of charging, but also increase the charging speed to a certain extent (10/13/32/63A).AC charging station and EV wall box are both mode 3.

4. Mode 4

Mode 4 is a DC EV charging station, which charges electric vehicles in a short time. It has high-power and high-voltage working conditions. Generally, it is not for household use, but it is specially set up in fast charging charging stations. The charging current in mode 4 is large, and the current is generally DC 80/125/200/250A, so the natural charging speed is also the fastest. However, DC charging has very high installation requirements and costs, and long-term DC charging will affect the life of the battery.

AC charging point design suggestion

  AC charging point design suggestion The following considerations should be considered when designing an AC charging point:   1. Charging power: current and voltage information. 2. Communication protocol 3. Protection level: Whether the angle between the cable of the charging pile and the pile body and the angle of the hanging ev plug conform to the drainage principle. 4. Dimensions: The outline dimensions of the ev plug fully conform to the latest national standard dimensions. 5. The charging ev plug homing structure. 6. If there is no one to guard, the ev plug homing detection and ev plug locking device should also be considered, and cannot be touched at will. 7. The service life of the cable. 8. Whether the material of the ev plug can be used outdoors. 9. The outer diameter of the charging cable.   From the above precautions, we see that the material of the AC EV plug is required to be used outdoors, then the material is required to have the following characteristics: weather resis

Will high energy density of lithium batteries affect safety?

 Will high energy density of lithium batteries affect safety? What is battery energy density? Since energy density is called density, it is the same concept as our junior high school physics, which represents the amount of electricity stored in a battery per unit volume/mass. That is to say, if the energy density of the battery is high, in order to achieve the same capacity, it is possible to carry fewer batteries and reduce the weight of the battery; Alternatively, with the same weight, bring more batteries to increase the battery capacity. What is energy density related to? The energy density of a battery is basically determined by the positive and negative electrodes of the battery, but only the active materials of the positive and negative electrodes cannot guarantee that the battery can generate electricity. There must be many non active substances, such as conductive aids, adhesives between active powders, isolation films, foil for the negative and positive electrodes, insulation

Why does the capacity of lithium batteries decrease in low-temperature environments?

 Why does the capacity of lithium batteries decrease in low-temperature environments? According to reports, the discharge capacity of lithium-ion batteries at -20 ℃ is only about 31.5% of that at room temperature. The working temperature of traditional lithium batteries is between -20~+55 ℃. Among numerous environmental factors, temperature has the greatest impact on the performance of lithium batteries. The electrolyte used in lithium batteries, as an organic liquid, like grease, can become viscous or even coagulate at low temperatures. At this point, the activity of conductive lithium salts inside is greatly restricted, resulting in low charging efficiency, which can lead to slow charging, insufficient charging, and discharge of lithium batteries at low temperatures.Lithium batteries are limited in their use in low-temperature environments, as their discharge capacity may severely decline and they cannot be charged at low temperatures. During low-temperature charging, the insertion o
