Guangzhou Auto Show Preview | Those models equipped with 4C and 5C rechargeable battery technology

"Charge for five minutes, talk for two hours". In the past, we could only see such a slogan in some mobile phone advertisements. With the continuous progress of battery technology in new energy vehicles, 4C and 5C batteries with "charge for ten minutes and battery life of 400 kilometers" will also meet us soon. As the Guangzhou Auto Show is about to open, this issue will take stock of the new models equipped with 4C and 5C battery technology.

So, what are 4C and 5C batteries? First, let’s find out the meaning of the letter "C". The current value required for the battery to discharge its rated capacity within a specified time can be expressed by the numerical value of the rated capacity (C), which is equal to the multiple of the rated capacity of the battery in data value, and the unit is ampere (A). For example, when the battery capacity of a car is 100Ah, the discharge current of 1C is 100 A; The discharge current of 2C is 200A, so 4C has reached 400A A.. Similarly, high discharge rate also means the improvement of battery charging ability, which is naturally of great concern to consumers. According to the calculation of power = current× voltage, on the basis of 800V high-voltage platform widely used in high-discharge rate battery models, if a battery with a capacity of 100Ah has a discharge rate of 4C, it can input a charging current of 100×4=400A, and then multiply it by 800V, which is the charging power of 320kW per hour. In other words, it only takes ten minutes to charge, and it can charge about 53.3 kWh, which brings considerable power.

Tucki X9 is Xpeng Motors’s new flagship MPV. He Xiaopeng once said that Xpeng Motors will use this model to open the "young" MPV market. Indeed, judging from the design of Tucki X9, the route taken by Tucki X9 is really different from other pure electric luxury MPVs, and the contour lines of the front and rear of the new car are more dynamic.

Coupled with Tucki’s proud advanced intelligent driving and rear wheel steering blessing, it seems that Tucki X9 will focus more on the main driving.

As for the battery, Tucki X9, like Tucki G9 and G6 before, is built by Tucki’s whirlwind architecture, and also adopts 800V high-voltage platform. The battery is ternary lithium-ion battery from Zhongchuang Singapore Airlines. According to speculation, the 4C battery technology provided by Tucki G9 should also appear on Tucki X9, and this 4C battery is still from Kirin 4C battery in Contemporary Amperex Technology Co., Limited. On the 2023 Tucki G9, the Kirin 4C battery appeared as an optional package. On the 2024 Tucki G9, the 4C battery option package disappeared. Generally speaking, whether Tucki X9′ s energy-supplementing efficiency can reach 4C still needs further information.

The ideal first pure electric MPV model-the ideal MEGA is quite hot, and the new car will also be booked at the Guangzhou Auto Show. It can be said that in addition to the appearance of a high-speed train locomotive, the concept of "5C" seems to be the beginning of the ideal MEGA. As the saying goes, "literature is no first, martial arts is no second". When it comes to 5C, people will think of the ideal MEGA first, and this label is even labeled. Of course, the ideal MEGA is not only popular in off the charts, but also has many mysteries. What we can know is that it is expected to be equipped with Contemporary Amperex Technology Co., Limited Kirin 5C battery for the first time, with a peak 5C charging rate, a peak charging current of 700A+ and a peak charging power of 520kW+. The official claim is that it has "brought the fastest charging speed of electric vehicles in the world-charging for 500 kilometers in 12 minutes".

Wubo HT: Haobo 5C Flash Rechargeable Battery

Haobo HT is the third model of Haobo brand. It is positioned as a medium and large pure electric SUV, and it was officially launched on November 15th, with a price of 213,900-329,900 yuan. The new car is built on the pure electric platform of AET3.0 and the electronic and electrical architecture of Spirit. The length, width and height of Haobo HT are 4935x1920x1700mm and the wheelbase is 2935mm, which really gives everyone a big surprise.

In addition, another killer configuration of Haobo HT is that it is equipped with an overcharged battery of up to 5C, which is officially called Haobo 5C flash charging technology. This is a set of closed-loop technology from recharging to battery. It is officially claimed that it can charge for 8 minutes and last for 400+ kilometers, and it will land earlier than the ideal MEGA.

Write at the end:

At the presentation conference of Zhijie S7, Yu Chengdong described the charging of Zhijie S7 as follows: charging for 5 minutes can last for 200+km, and charging for 15 minutes can last for 400+km. Take a closer look, that is to say, the approximate 4C charging power that Zhijie S7 can actually achieve may be 5 minutes in an ideal situation, and the charging power for the next 10 minutes will become 2C; For another example, the charging rate advertised by the ideal MEGA at first was not 5C, but 4C, but after it was changed to 5C, the heat of the ideal MEGA reached the second peak after its appearance was announced.

Higher fast charge rate is naturally the focus of current technical research, but from the consumer’s perspective, the actual experience of recharging is equally important. Only by the long-term word-of-mouth accumulation of users can we know more real feedback. I hope that the fast charging technology of "charging for 10 minutes and cruising for 400 kilometers" can be popularized on a large scale and really change people’s travel life.
