Smart Extreme-Weather Protection

The first EV-grade full-tab cells deliver higher capacity with lower resistance, less heat, and longer-lasting performance. 25% More Efficient power flow (thanks to lower resistance: 1.5 mΩ vs. 2 mΩ) 25% Less Self-Heating

Perfectly matched cells ensure identical capacity, voltage, and resistance, minimizing wear and maximizing battery life. 24/7 Self-Maintenance: Automatic SOC balancing maximizes efficiency across the battery’s entire lifespan.

Local BMS – X-Guard® System: 44+ safeguards and comprehensive monitoring ensures all-around safety. Safeguards: overcharge/discharge, extreme temperatures, short circuits, component failures, and more Cloud BMS – Big Data Protection: 100+ anomaly detectors run 24/7, with instant alerts, local service response, and remote emergency support.

Power Protection: 1.2M circuit samples/sec, millisecond-level anomaly detection for inverter and battery. Connection Monitoring: Intelligent cable and interface safeguards track heat, recognize faults, and allow instant shutdown for total electrical security. Load Isolation: Continuous voltage/current monitoring with triple-layer isolation. Faulty devices are cut off automatically while critical loads stay powered.

Heats batteries in extreme cold for safe charging and longer runtime, while high-temp protection allows charging even at up to 45°C (113°F).
