Hongqi moves solid-state battery into real-vehicle testing with Tiangong 06, 2027 rollout planned
Hongqi announced on December 31 that its first independently developed solid-state battery pack had been successfully installed in a Hongqi Tiangong 06 prototype vehicle, according to Y-Auto. The prototype completed trial production and rolled off the line, marking the transition of Hongqi’s all-solid-state battery program from laboratory validation to real-vehicle testing. The development represents a vehicle-level integration milestone.
According to Hongqi, the battery pack was developed by its Research and Development Institute and is the first complete all-solid-state system the brand has installed in a production-intent vehicle. The company stated that this step formally initiates on-vehicle testing focused on system integration, operational stability, and safety performance under automotive conditions.
The Tiangong 06 serves as Hongqi’s dedicated electric SUV platform for advanced powertrain and battery testing. The model is a battery electric mid-size SUV built on the Hongqi Tiangong Architecture and is already offered in the Chinese market with conventional lithium-ion battery configurations. Existing versions are positioned in the mid- to high-end electric SUV segment and offer both rear-wheel-drive and all-wheel-drive layouts, making the model suitable for evaluating different drivetrain and battery system integrations.
Hongqi stated that the solid-state battery prototype followed a concentrated 470-day development program. During this period, research efforts focused on sulfide-based solid electrolytes, validation of 10 Ah cell performance, and 60 Ah cell manufacturing processes. The company reported multiple staged technical breakthroughs in these areas, but did not disclose energy density, charging performance, or durability metrics.
The company also confirmed progress in high-voltage-resistant battery module packaging and system-level lightweight integration. These areas are critical to adapting all-solid-state batteries to vehicle platforms, particularly for electrical insulation, structural integration, and packaging efficiency within existing electric vehicle architectures.
Previous reports indicate that FAW plans to introduce solid-state battery technology into Hongqi vehicles by 2027, beginning with limited deployment in selected flagship sedans and SUVs. The Tiangong 06 prototype aligns with this timeline by functioning as a validation platform for vehicle-level testing ahead of potential small-batch production.
FAW Hongqi did not announce pricing, production schedules, or specific market plans related to solid-state battery-equipped vehicles. The company stated that subsequent development phases will continue to focus on cell performance verification, module reliability, and system integration testing.
