NIO’test vehicle rushed out the third floor of building,2 test drivers died

At about 17:22 on June 22, 2022, a NIO test vehicle rushed out of the third floor of Building 8 of Shanghai Automotive Innovation Port and fell to the ground. The accident resulted in the death of two test drivers.

On June 23, NIO's official Weibo responded to the accident, saying that among the two victims, one was a company colleague and the other was a partner employee. The company has set up a special team to help family members deal with the aftermath.

According to the live video of Dahe Daily, the car rolled over and was seriously damaged. Several people tried to lift the car together. Five firefighters dismantled the car and broke the window to rescue. Some glass pieces and white cement wall blocks were scattered around.

According to the surging news report, after the accident, the reporter learned from relevant departments that this time a NIO test car fell from a height, causing two test drivers to be injured. Rescue. One of the test drivers died due to ineffective rescue, and the other was declared dead in the early morning of the 23rd after the hospital's operation was ineffective.

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

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

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
