24 V100Ah truck start/park integrated sodium-ion battery

Exceptional Low-Temperature Operation: Designed to perform reliably in extreme cold, operating down to -40°C and delivering 75-80% of its rated capacity at this temperature without requiring pre-heating.

High Power Output for Demanding Applications: Provides a massive 1600A instantaneous pulse current (0.1S at -20°C) for cold cranking large truck engines and a continuous discharge current of 150A for parking AC systems.

Advanced BMS with Automatic Cold Charging: The smart BMS features an automatic heating function when charging below 0°C, enabling safe charging in sub-zero environments down to -40°C.

Superior Longevity & Cycle Life: Constructed with high-grade sodium-ion cells from Zhongke Haina, offering an extended cycle life of up to 5000 cycles and a design life exceeding 10 years.

Robust & Protected Construction: Housed in a rugged galvanized steel case with IP65 waterproof and dustproof rating, internal sealing, and insulation for maximum durability in vehicle and outdoor environments.

Comprehensive Safety Protections: The BMS includes overcharge, over-discharge, over-current, and short-circuit protection. Cells themselves are exceptionally safe, passing nail penetration, crush, and impact tests without fire or explosion.

High Efficiency & Minimal Self-Discharge: Achieves charge/discharge efficiency of ≥90% at 25°C, ensuring effective energy use and longer runtime for applications like parking air conditioning.

Wide Operating Temperature Range: Can be discharged across a wide range from -40°C to 60°C and stored from -30°C to 60°C, offering great flexibility for various climates and conditions.

Maintenance-Free & Excellent Storage: Requires no maintenance and can be stored for long periods with minimal capacity loss, significantly reducing the total cost of ownership.

Compliance with Safety Standards: The battery pack is designed and tested in accordance with stringent international safety standards, including GB38031 (equivalent to UN ECE R100 for EVs), ensuring reliability and safety.
