Analysis Report: Charging New Energy Vehicles Using Charging Piles in Extremely Cold Weather

I. Analysis of the industry situation

 

The new energy vehicle industry has been developing rapidly in recent years, with the global sales of new energy vehicles continuing to grow, and policy promotion and technological advances have also played an important role in boosting the industry. In the field of new energy vehicle charging facilities, the construction of charging piles is also accelerating, including public charging piles, specialized charging piles and family charging piles.

However, in extremely cold regions, using charging piles to charge new energy vehicles can be challenging due to falling temperatures. According to statistics, extreme cold temperatures can negatively affect the charging effect of electric vehicle batteries, slowing down charging and possibly even leading to charging interruptions. Therefore, targeted technical solutions and product innovations are needed to meet the demand for charging new energy vehicles with charging piles in extremely cold areas.

 

II. Leading Technologies

 

As of August 2023, the following leading technologies have achieved significant results for the use of charging piles to charge new energy vehicles in extremely cold weather:

1. Heating cable technology: This technology preheats the charging pile at low temperatures by using a heating cable inside the charging pile to ensure that the charging facility operates at close to room temperature. This effectively improves charging efficiency and reduces the impact of low temperatures on battery performance.

2. Intelligent heating film technology: This technology realizes accurate heating of the charging facility in a low-temperature environment by laying an intelligent heating film on the surface of the charging facility. This heating method has the advantages of high efficiency and energy saving, and can effectively prevent overheating.

3. Heat Insulation Material Technology: By using advanced heat insulation materials, such as phase change materials (PCM), in key parts of the charging facility, it can effectively slow down heat dissipation and improve the heat preservation performance of the equipment.

4. Preheating Battery Technology: This technology improves the performance of batteries in low-temperature environments by preheating them. Among other things, the use of electric heating elements and heat pump technology for battery preheating has been shown to have significant effects in improving battery charging efficiency and extending battery life.

5. Optimized charging protocol technology: Researchers are working to optimize charging protocols to adapt to charging needs at different temperatures. For example, technologies such as pulse current charging and multi-stage charging can be used to effectively adapt to low-temperature environments and improve charging efficiency.

6. Composite material technology: Charging pile shells made with composite materials have excellent thermal insulation properties, which can effectively reduce the impact of external ambient temperature on internal equipment.

7. Energy storage technology: combining renewable energy (such as solar energy, wind energy, etc.) with energy storage equipment, energy can be stored in advance during the day when there is enough sunlight or wind, and then use the stored energy to charge the new energy vehicles when there is no sunlight or wind at night in the extreme cold, to ensure the continuous supply of energy.

8. Wireless charging technology: Wireless charging technology can be used to charge new energy vehicles without directly connecting to charging piles. This technology reduces energy loss during charging and improves charging efficiency. In a low-temperature environment, wireless charging technology can reduce heat dissipation at the charging interface and improve charging efficiency.

III. Conclusion

 

Although extreme cold weather poses a challenge to the charging of new energy vehicles, with the progress of technology, we have found a series of effective solutions. These technologies not only improve charging efficiency, but also reduce the impact of low temperature on battery performance. Therefore, investors should pay attention to these leading technological solutions when investing in new energy vehicle charging facilities to get a better return on investment.
