Recently, our company officially launched a new generation of low-temperature lithium battery pack series. Designed specifically for extremely cold and harsh environments, these batteries maintain excellent charge–discharge efficiency and cycle life even under extreme low‑temperature conditions as low as –40°C. Paired with an intelligent BMS battery management system, they provide safe and reliable power solutions for specialized regions and equipment.

Conventional lithium batteries begin to experience performance degradation below 0°C; when the temperature drops below –20°C, their internal resistance rises sharply, leading to a substantial reduction in usable capacity and a marked increase in the risk of lithium plating during charging—potentially resulting in system failure. For traditional lithium batteries, capacity loss at temperatures below –30°C can range from 50% to 70%, severely limiting their applicability in extremely cold regions. Our company’s newly launched low‑temperature lithium battery pack, leveraging a high‑performance low‑temperature cell architecture and several proprietary core technologies, has comprehensively overcome this low‑temperature performance bottleneck.

Outstanding charge–discharge performance at −40°C, ensuring reliable operation even in extreme cold.

Our company’s low‑temperature lithium battery packs utilize brand‑new, A‑grade, low‑temperature‑specific cells, paired with an optimized low‑viscosity electrolyte system and low‑temperature additives. This significantly enhances the migration rate of lithium ions in extremely cold environments and effectively suppresses lithium plating under such conditions. The product supports normal discharge at –40°C, with a capacity retention of over 70%, and operates across a wide temperature range from –40°C to +60°C. An optional intelligent electric heating system is available, ensuring stable charge–discharge performance even in the harshest –40°C conditions. In terms of cycle life, the cells can exceed 3,000 cycles, meeting the demanding requirements of long‑term, continuous, maintenance‑free operation in polar scientific research and specialized monitoring equipment.

In terms of safety, the product features a reinforced diaphragm design that effectively prevents lithium dendrite penetration, ensuring excellent mechanical stability under thermal cycling conditions. The battery system incorporates multiple protection mechanisms, including overcharge, overdischarge, overcurrent, short-circuit, and temperature‑abnormality safeguards, which collectively prevent thermal runaway, ignition, and explosion even under extreme conditions.

Intelligent BMS with all‑round management and precise temperature control adapted to low‑temperature conditions.

The battery management system is the core enabler for the stable operation of low-temperature lithium‑ion battery packs. Our company’s independently developed BMS incorporates a low‑temperature adaptive algorithm that continuously monitors critical operating parameters such as cell voltage, current, and temperature, and intelligently adjusts charging and discharging strategies under low‑temperature conditions.

The BMS system’s key functions include: intelligent thermal management, which continuously monitors battery temperature and automatically determines whether to activate the heating module; low‑temperature charging protection, which forcibly limits the charging current below –30°C to prevent lithium metal deposition and dendrite formation; a multi‑stage heating strategy that intelligently applies staged heating based on the battery’s varying temperature zones, balancing energy consumption with heating speed; intelligent SOC/SOH correction, which provides dynamic compensation in cold environments to ensure accurate and reliable state‑of‑charge estimation; and post‑heating charging control, which ensures the battery pack switches to normal charging mode once its temperature reaches a safe threshold, thereby eliminating low‑temperature charging safety risks at the source.

Full‑solution customization, widely adaptable to the needs of specialized fields.

To meet the diverse needs of different application scenarios, our company offers end-to-end customized solutions—covering cell selection, BMS configuration, thermal management system design, as well as enclosure structure and communication interface.
