Understand the Chedi winter test charging compatibility issues can be considered as a test item

Mondo Technology Updated on 2024-01-30

The 2023 winter test of Chedi is underway, and it can be seen from the released low-temperature charging test list that AVATR with 800V system, Zhiji and Xpeng have obvious advantages in low-temperature chargingThe Audi RS, which is also an 800V platform, should be the first on paper, but it is indeed incompatible with the liquid-cooled supercharging terminal on site, and cannot achieve high-voltage fast charging, and the results are lagging behind.

With the continuous maturity of 800V platform technology and the reduction of costs, it is expected that more new energy vehicle manufacturers will adopt 800V platforms in the future. Both the battery life and the charging speed are huge improvements. So, do ordinary users need to consider the compatibility of high-power charging when buying electric vehicles?

The charging terminal of electric vehicles is divided into overcharging and slow charging, and the overcharging terminal generally adopts a high-voltage and high-current method, which can replenish the power of the electric vehicle in a relatively short timeOrdinary slow charging, on the other hand, uses a lower voltage and current, and the charging time is relatively long. For ordinary users, if the purchased electric vehicle can only be charged at a specific charging station with high voltage and high current, the charging efficiency will be greatly limited during the journey.

According to the latest data released by the Charging Alliance, as of November 2023, members of the Alliance have reported a total of 262 public charging piles60,000 units, car company brand stations are still very rare. In the field of public mobility, charging mainly relies on the public fast charging stations of charging operators. It is very important to support the compatibility of super-fast charging vehicles with charging stations of leading operators.

According to public data, there are two companies that have built a supercharging network, Telai and Tesla.

Special call charging station.

As a leader in the charging industry, Telai is also the first company in China to release high-power liquid-cooled supercharging technology, with a charging power of up to 600kwThe charging terminal of Telai supports a wide voltage range of 200V-1000V, which can meet the charging voltage needs of almost all electric vehicles. At the same time, the charging terminals of Telai have achieved interconnection with different car brands, supporting a variety of different fast charging protocols and standards, so that different brands of electric vehicles can enjoy supercharging services in their charging stations.

Tesla Supercharge.

The charging power of the Tesla V3 Supercharger has reached 250kW. Although the voltage and current output can be adjusted according to different models, the maximum output voltage is 400V, which is different from the current route of 800V high voltage and low current to increase charging power. Tesla Supercharge also announced that it is open to charging, and as an emergency charge, it is also optional.

Here I also put forward a suggestion for the test of understanding Che Didong, and set up some more links for the charging test. For example, the charging compatibility list of public charging stations, the measured power list, the maximum charging power duration, the one-time charging success rate, etc. After all, after an electric car buys an electric car, the charging problems are more frequent than acceleration and climbing.
