1000V high-voltage SIC platform, the second generation of "blade battery" BYD's new technology is coming
2023 is coming to an end, and the automobile market will also usher in a new round of "reshuffle". But when it is puzzling, there is no BYD among the car companies participating in the game, has BYD never thought about this aspect?
It is true that BYD did not release 800V high-voltage SIC technology this year, or even intelligent driving system, etc., but only brought the DM-o hybrid system and "Yi Sifang". But this does not mean that BYD will give up these two core technology competition points. A few days ago, a netizen shared that BYD will bring a series of new technologies such as the 1000V high-voltage SIC platform next year. The details are as follows:
Judging from the sharing of netizens, in addition to the 1000V high-voltage SIC platform that BYD will launch next year, it will also have a new DM5.0 super hybrid platform, as well as a second-generation "blade" battery with higher energy density and longer mileage.
Seeing this, there may be a guy version who will say, BYD has not even released 800V, is it possible to jump directly to 1000V? At first, we were puzzled when we saw this news, but with the review of the data, we found that the 800V high-voltage platform BYD had already been completed and put into use.
In 2015, BYD launched the 800V high-voltage platform for passenger cars for the first time, and was the first to install it on the Qin EV (2015 model), with a charging termination voltage of 752.4V, and the Tang DM (2015 model) charging termination voltage is as high as 820V. At that time, the market was full of low-voltage cars, and only BYD used high-voltage until after 2019, when Porsche was the first to catch up, four years later than BYD.
Having said that, as far as we know, BYD models such as the Qin PLUS EV and Han EV, which are currently in volume, have not shown strong competitiveness in terms of charging efficiency. In the case of the Han EV, the maximum charging power is only 120kW, which is more than double that of Porsche's 270kW.
In fact, this is also normal, after all, the rise of fast charging piles has also been in the past two years, and the current energy replenishment network in many places has not yet reached the mainstream 400V. Therefore, even if BYD models support 800V high voltage, they cannot maximize power due to the local energy supply network.
As for why later new forces such as Ideal and Xiaopeng can achieve 800V fast charging, the most critical time is that they are building their own energy replenishment networks. In this case, why doesn't BYD do energy supplemental network? I believe this is also a point that many car lovers are more concerned about, after all, BYD has a greater advantage in terms of strength and volume. The Travel Bureau believes that the key to BYD's non-self-built energy supplement network is that most of BYD's models are economic and mid-range products.
Their customer base is more price-sensitive, while the products of new forces such as Ideal are in the mid-to-high-end price range, and they pay more attention to the user's experience. In addition, although BYD has not built its own charging piles, many brands of charging piles on the market BYD have also participated in the formulation. In other words, compared with one-to-one to improve the user experience, BYD has chosen a "one-to-many" model with higher compatibility, that is, the car does not pick piles.
However, having said that, it is indeed time for BYD to improve the charging efficiency of vehicles, after all, this is also the direction of the current market development. At the same time, for consumers, energy anxiety is greater than mileage anxiety. Therefore, it is foreseeable that the launch of BYD's 1000V high-voltage SIC platform will also cause market changes, after all, from the advertised 5-8 minutes to supplement 500km, it is comparable to traditional fuel vehicles. So, can this technology make it happen?
