Geely has introduced a new electric drive system called “Thunder” that integrates multiple components into a single unit. This compact and lightweight system aims to improve efficiency and reduce weight in electric vehicles.
Innovative All-in-One Design
The Thunder system combines 12 hardware components into one enclosure, including the motor, motor controller, DC-to-DC converter, onboard charger, and battery management systems. This integration reduces the need for extensive wiring and extra parts.
- 30% less high-voltage wiring
- 15% less low-voltage wiring
- Eliminates over 180 components compared to conventional setups
- Compact housing made from magnesium, only 12.8 inches (325 mm) tall
Impressive Performance and Efficiency
The electric drive weighs just 75 kg (165 pounds) and delivers 328 horsepower in its single-motor version. Geely claims a record production-level efficiency of 93.8%, attributed to the system’s tight integration and smart design.
- Power density of 11.8 kW/kg
- Compact size frees up to 28 liters of trunk space
- First application in the Geely Galaxy TT electric sports sedan
Geely Galaxy TT Sports EV
The first car to use the Thunder drive system is the new Galaxy TT electric sedan. It offers a single-motor version with 328 hp and a dual-motor all-wheel-drive option producing 570 hp. The vehicle uses an 800-volt architecture and offers three battery sizes:
- 52.4 kWh
- 63.8 kWh
- 75.2 kWh
It can achieve an estimated maximum range of up to 725 km (450 miles) under the CLTL standard.
Why It Matters
Geely’s Thunder electric drive system shows how integrating key components can enhance efficiency, reduce weight, and save space in EVs. This approach could help engineers push EV performance and packaging forward without increasing costs or complexity. The Galaxy TT will be an interesting model to watch when it launches with this new technology.
