CPCA reports that Chery plans to begin vehicle validation of solid-state batteries in 2027, while a separate semi-solid version is planned for installation in vehicles in the fourth quarter of 2026. CPCA also reports that Chery says its dedicated solid-state cells have reached an energy density of 400 Wh/kg.
For a BYD Han owner in Europe, this is a signpost rather than a benefit arriving soon. CPCA’s report gives no vehicle range figure, charging-speed figure, production launch date, or retrofit path for cars already on the road.
When will Chery test solid-state batteries in cars?
CPCA reports that Chery plans to carry out vehicle validation of its solid-state battery in 2027. The publication says the plan was disclosed on 3 September at the 2026 World Power Battery Conference in Yibin, Sichuan.
That wording matters. Vehicle validation is not the same thing as a battery appearing in customer cars at scale. CPCA reports a planned validation date, not a launch date for a finished production EV.
For someone looking at a replacement electric car rather than a laboratory announcement, 2027 is still a future checkpoint. It is useful because it puts a date beside a technology that has spent a long time being discussed mostly without dates.
How does Chery’s semi-solid battery plan compare with its solid-state plan?
CPCA reports two separate battery paths: a semi-solid version planned for vehicle installation in late 2026, and solid-state battery validation planned for 2027.
| Battery path reported by CPCA | What CPCA says is planned | Timing stated by CPCA |
|---|---|---|
| Semi-solid version | Planned to be installed in vehicles first | Fourth quarter of 2026 |
| Solid-state battery | Planned for vehicle validation | 2027 |
| Dedicated solid-state cell | Energy density has reached 400 Wh/kg | No production timing stated |
That is a much more useful distinction than treating every battery called “solid-state” as the same thing. CPCA describes a semi-solid version going into vehicles before the full solid-state programme reaches its validation stage.
Does a 400 Wh/kg battery mean more real-world range?
CPCA reports that Chery’s dedicated solid-state battery cells have reached an energy density of 400 Wh/kg. CPCA does not state what range that would produce in a particular vehicle, at a particular speed, in a particular temperature, or with a particular battery size.
So no, 400 Wh/kg is not a motorway-range number. It is a cell energy-density figure.
That distinction is worth keeping very clear. A car can have an impressive battery headline and still give a different answer on a motorway, where speed and conditions matter more than brochure language. I wrote about exactly that gap in my BYD Han motorway range experience.
The interesting part for future replacement cars is that higher cell energy density may give manufacturers more room to choose between a larger pack, a lighter pack, or some compromise between the two. That is an interpretation of the direction, not a performance promise from CPCA or Chery.
Is Chery saying solid-state batteries are ready now?
No. CPCA reports that Chery plans vehicle validation in 2027, which means the company is still describing a future verification stage for the solid-state battery.
CPCA also reports that Chery follows a principle of advancing multiple battery solutions at the same time and not putting a battery into a vehicle unless it is sufficiently safe. That is Chery’s stated approach as reported by CPCA, not proof that a production solid-state battery is ready today.
There is a useful bit of restraint in that. Battery announcements tend to make every next-generation cell sound like next year’s normal equipment. Here, the reported schedule separates the near-term semi-solid installation plan from the later solid-state validation plan.
Will Chery’s battery plan improve charging for current BYD owners?
CPCA’s report does not give a charging-rate claim for either the semi-solid or solid-state battery programme. It also does not describe an upgrade path for existing cars, including a BYD Han already driving in Europe.
So this is not a reason to expect a software update, a replacement pack, or faster charging on a current car. Nothing in the CPCA item says that.
It is still relevant to owners because battery technology changes the choice available when the time comes to replace a car. Range, pack weight, safety requirements and charging behaviour are not separate things in real ownership, even if this particular announcement only gives a number for energy density and dates for Chery’s plans.
How much is Chery investing in solid-state battery research?
CPCA reports that Chery plans to expand its dedicated solid-state battery team to more than 1,200 people over the next two years. CPCA also reports planned cumulative dedicated research and development spending of more than 10 billion yuan.
Those are Chery’s reported plans, not completed results. Still, they show that this is being treated as a serious development programme rather than one experimental cell shown at an event.
The boring answer is probably the honest one: Chery’s 2027 validation plan does not change the car parked outside today. But it does make solid-state batteries feel slightly less like a permanent “maybe next decade” story.
FAQ
What did Chery announce about solid-state batteries?
CPCA reports that Chery plans to begin vehicle validation of its solid-state battery in 2027. The CPCA item says the plan was disclosed at a battery industry conference on 3 September 2026.
When will Chery put a semi-solid battery into a vehicle?
CPCA reports that Chery plans to install its semi-solid version in a vehicle first in the fourth quarter of 2026.
What energy density did Chery report for its solid-state battery cell?
CPCA reports that Chery’s dedicated solid-state battery cell has reached an energy density of 400 Wh/kg. CPCA does not give a vehicle range figure alongside that number.
Does Chery’s announcement promise faster charging?
No charging-speed figure appears in CPCA’s report. CPCA reports the planned validation date, the semi-solid installation plan, the 400 Wh/kg energy-density figure, and Chery’s planned research expansion.
Will this upgrade an existing BYD Han in Europe?
Nothing in CPCA’s report describes retrofitting existing vehicles or upgrading a BYD Han in Europe. The item concerns Chery’s planned future battery development and vehicle validation.
How many people does Chery plan to put on solid-state battery research?
CPCA reports that Chery plans to expand its dedicated solid-state battery team to more than 1,200 people over the next two years, with cumulative dedicated research and development spending planned to exceed 10 billion yuan.
