Physix FrontierGeely Galaxy TT's 'Triple High-Voltage' Naming Reveals More Than Just 800V Architecture
I've seen this kind of "make-do" approach in quite a few reviews. Some so-called 800V vehicles have chargers that support 800V, but the in-car AC compressor and DCDC converter are still 400V, leading to reduced actual efficiency. Geely specifically emphasized "full-domain" this time, adding "three high-voltages," which is somewhat hinting at their higher system integration level. But then again, you can package technical terms however you like; real-world implementation is what counts. I've seen too many "full-domain" concepts where the user experience didn't differ much in the end.
Regarding the actual value of 800V, as an independent developer, I care more about its marginal benefit in real scenarios. The AWD version with a peak power of 425kW theoretically charges very fast, but the question is: how many ultra-fast charging piles in China can handle this power? Currently, most third-party fast-charging piles still have a peak power around 250kW, and many are only 120kW. The true advantage of the 800V platform is actually maintaining high-power charging for a longer duration when the battery is low, rather than just looking at the peak numbers. Geely didn't explicitly say this, but I guess their technical documentation should have relevant curves.
Additionally, parameters like 245kW for a single motor and 425kW for dual motors aren't aggressive in the 2025 market. The XPeng G6, NIO ET5, and Tesla Model 3 Performance are all roughly in this range. But Geely making "Qianli Haohan Assisted Driving H7" a main selling point did surprise me a bit. This "H7" naming sounds like a hardware-level solution classification. I guess it might be based on a smart driving platform using 7nm chips, or perhaps a configuration with 7 cameras. It's unlikely to be a pure vision solution because the brand name "Qianli Haohan" was previously promoted by Geely for commercial vehicles, focusing on multi-sensor fusion.
From a developer's perspective, implementing assisted driving solutions is more challenging than hardware specs. I've written some small image processing tools myself and deeply understand that algorithm robustness is harder to achieve than raw computing power. Even if the H7 solution uses LiDAR + HD maps, if software iteration doesn't keep up, users will find it turns from "adding wings to a tiger" into "gilding the lily." Geely's biggest problem right now isn't technical reserves, but how to convert tech stacking into experiences users can perceive. For example, with 800V, users care more about "how long does it take to charge once on the highway" or "will turning on AC cooling affect range," rather than terms like "full-domain three high-voltages."
Layer by layer, I want to make a core point: Geely Galaxy TT's technical launch this time is essentially a "defensive offense." At this point in 2025, 800V and smart driving are already standard features for models over 200k RMB, so Geely must keep up. But its differentiation lies in the system integration of "three high-voltages" and the branded smart driving system "Qianli Haohan." This is a bit like independent developers building products: instead of adding features, it's better to subtract inefficiencies in the system. If Geely can reduce energy consumption by 10% with 800V, or achieve 99% compatibility with charging piles, that's more valuable than simply stacking power.
Finally, my trend prediction is: In the next two years, the 800V platform will shift from a "selling point" to a "standard feature," and what truly determines user experience will be automakers' investment in charging infrastructure and the frequency of smart driving software iterations. If Geely Galaxy TT can publish actual data on how "three high-voltages" improves charging efficiency, such as 10%-80% charging time and cold-weather charging speed, that would be what truly moves users. Otherwise, this is just another "spec sheet launch event," and users will just say after seeing it: "Oh, another 800V, so what?"
