Automotive Battery Thermal Management System for Electric Vehicles
Product Overview
The automotive battery thermal management system (BTMS) is designed to provide effective heat control, thermal insulation, and safety protection for electric vehicle (EV) battery packs operating under varied and demanding conditions.
Developed by BSTFLEX, this system integrates radiant heat shields, high-temperature insulation materials, and protective barriers to maintain optimal battery temperature, reduce heat transfer, and support EV battery safety and durability.
The solution is suitable for passenger EVs, commercial EVs, trucks, buses, marine EV platforms, and automotive energy systems.
