Battery Thermal Management System (BTMS)

Thermal management systems for electric vehicle (EV) and hybrid battery packs

Saiensi specializes in the production of vehicle thermal safety management systems, supported by a CNAS-certified laboratory and an 80% in-house manufacturing rate. We maintain strict control over materials, cost management, delivery, and quality.

Saiensi’s battery thermal management system (BTMS) ensures that vehicle batteries operate within the optimal temperature range during charging and discharging, enabling safe, efficient, and long service life performance.

• High-temperature rapid cooling: Effectively dissipates heat when the lithium battery temperature rises, preventing or delaying thermal propagation that could cause fire or explosion during charging, and reducing the risk of thermal runaway.
• Low-temperature rapid heating: Preheats the battery under low-temperature conditions to ensure safe and efficient charging and discharging in cold climates, eliminating winter driving range anxiety for new energy vehicles.
• Forced circulation cooling: Minimizes internal temperature differences within the battery pack, preventing localized overheating and uneven aging, thereby extending overall battery life.
• Automatic control: Integrates real-time battery monitoring and intelligent control. The system automatically switches between shutdown, cooling, heating, and self-circulation modes based on operational data and battery status.
• All-climate operation: Designed to perform reliably across diverse climates and driving conditions of new energy vehicles.
• High compatibility: Supports online programming, firmware updates, and remote diagnostics.
