Background
Electric tractors must maintain stable battery temperatures during field work, transport, charging, and seasonal climate changes. Compared with passenger EVs, agricultural machinery often works longer at lower speeds and under harsher contamination conditions, making thermal control consistency and packaging integration more critical.
Typical Challenges
- Battery temperature rises quickly during high-load field work in hot weather.
- Low-temperature startup and charging performance become unstable in cold seasons.
- Long continuous operation leads to thermal accumulation in the battery pack.
- Vehicle integration space is limited and requires compact system packaging.
