No verified evidence in the reviewed company material shows Chery has a 2026 production EV that travels more than 600 miles on a charge in Arctic temperatures. Chery has reported ambitious figures for its Rhino S solid-state battery module, but the company’s filing describes vehicle integration testing as planned for 2027. Toyota’s 2026 range target is for a separate next-generation battery program; Toyota’s all-solid-state BEV target is 2027–2028.
What Chery has actually announced
Chery’s 2026 annual-report filing says the company unveiled its Rhino S solid-state battery module at its Global Innovation Conference on October 18, 2025. The filing reports a cell energy density of 600 Wh/kg and projects that a vehicle using the module could achieve 1,200–1,300 km of range—about 746–808 miles. Chery said initial vehicle integration testing was planned for 2027.
Those are company-reported specifications and a projected vehicle range, not the result of an identified independent road test. The filing does not identify a retail 2026 model, name a range-testing cycle, or report an Arctic-temperature vehicle test. In particular, the 600 Wh/kg figure is cell-level energy density; it is not a measure of miles driven per charge.
What the cold-weather examples do—and do not—show
Chery’s published material includes cold-weather claims for other technologies and vehicles, but they cannot establish Rhino S performance. A separate Chery technical page gives an operating-temperature range of −35°C to 60°C in a hybrid-powertrain context. Chery’s Fulwin A9 page advertises more than 700 km of measured range and 90% capacity retention at −30°C for a production model with an LFP battery. Neither claim concerns a Rhino S solid-state EV.

Chery’s 2024 ESG report describes multiple battery development paths and says the company had launched solid-state battery R&D. Its range figures apply to different battery types, so they should not be attributed to Rhino S.
What Toyota’s 2026 range target means
Toyota’s June 2023 battery roadmap sets a 1,000 km (about 621-mile) cruising-range target for a next-generation BEV planned for 2026. Toyota ties that target to its next-generation performance-version battery and vehicle-efficiency improvements—not to an all-solid-state vehicle. In September 2024, Toyota separately said gradual production of next-generation performance batteries was planned to begin in 2026.

Toyota’s all-solid-state BEV plans have a later target. Toyota’s June 2023 roadmap and its October 2023 announcement with Idemitsu Kosan describe a 2027–2028 goal for commercialization or market launch. The October announcement focuses on sulfide solid electrolytes, production methods and a supply chain; it also identifies durability as a technical challenge. Toyota CEO Koji Sato said a solid electrolyte could allow ions to move faster, enabling shorter charging times, greater cruising range and higher power output. That is an explanation of the technology’s potential, not a published result from a comparative vehicle test.
Chery and Toyota’s claims side by side
| Claim | What the company says | What it establishes |
|---|---|---|
| Chery Rhino S | 600 Wh/kg cell energy density; projected 1,200–1,300 km vehicle range, in Chery’s 2026 filing describing its October 2025 module announcement. | A company-reported cell figure and projected range. The filing planned initial vehicle integration testing for 2027; it does not establish a 2026 retail vehicle or Arctic-range test. |
| Toyota next-generation BEV | 1,000 km target for a BEV planned for 2026, in Toyota’s 2023 roadmap. | A target for a next-generation performance battery and vehicle-efficiency work, not Toyota’s all-solid-state BEV. |
| Toyota all-solid-state BEV | 2027–2028 commercialization or market-launch target, in Toyota and Idemitsu’s 2023 plans. | A roadmap target, not confirmation of retail availability or a measured vehicle range. |
These figures are not a like-for-like comparison. One is Chery’s projected range for a vehicle using a module still awaiting planned integration testing; another is Toyota’s target for a different battery program. Neither set of reviewed primary sources supplies comparable production-car results under the same range cycle or temperature conditions.

What would prove a 600-mile Arctic-range claim?
A credible comparison needs more than a battery specification or a company range projection. For each vehicle, readers would need to know:
- Vehicle and status: the exact model, whether it is a prototype or customer vehicle, and whether it is available to buy.
- Range method: the test cycle or route, and whether the figure is an official rating, a company projection or a measured result.
- Cold conditions: ambient temperature, battery preconditioning, route and speed, heating and defrost use, and the test procedure.
- Battery evidence: what the energy-density figure measures, along with charging conditions and durability data.
Without those details, a cell-level energy-density figure cannot be converted into real-world range, and a result for a different battery chemistry or vehicle cannot confirm Rhino S performance in the cold.
Is Chery “schooling” Toyota?
The available announcements do not support that conclusion. Chery has disclosed an ambitious solid-state module specification and projected vehicle range, while its filing places initial integration testing in 2027. Toyota’s all-solid-state target is later than its separate 2026 next-generation battery plan. Neither company’s cited roadmap or announcement provides a comparable, independently verified production-EV test showing the other has been beaten on range—especially in Arctic conditions.
