Indonesia’s national electrification roadmap plans to replace thousands of fuel heavy trucks for inter-island freight with zero-emission electric models before 2030. These electric heavy trucks carry agricultural products, aquatic goods and industrial supplies across islands, operating under year-round high temperature and high humidity marine climate. The closed and humid vehicle cabin accelerates uneven heat accumulation of lithium battery packs, triggering frequent overheating alarms and shortening vehicle driving range, which becomes the core bottleneck restricting large-scale promotion of electric heavy trucks in Indonesia. Newbase launches archipelagic climate optimized Humidity Adapted BTMS to solve the battery thermal management pain point of local electric heavy-duty fleets.
Ordinary liquid cooling BTMS cannot discharge condensed water generated by high-humidity air inside the cooling pipeline, easily causing pipeline blockage and reducing heat dissipation efficiency. The exclusive Archipelagic Liquid Cooling circulation system of Humidity Adapted BTMS adds automatic condensate drainage structure, adapting to the humid air environment of all Indonesian islands. The built-in close-fitting Truck Battery Cooler covers the bottom and side of heavy truck battery packs, transferring accumulated heat to coolant rapidly even when vehicles run continuously under 42℃ tropical ambient temperature. Local electric truck test fleets in Sumatra verified that installing Humidity Adapted BTMS extends single-charge driving range by 18%, and reduces battery failure rate caused by high humidity heat accumulation by nearly 45%.
For Indonesian local heavy-duty electric vehicle assembly factories with independent chassis R&D capability, Newbase provides fully configurable Custom BTMS Set. Clients can adjust the coolant flow rate of Archipelagic Liquid Cooling, modify the layout of Truck Battery Cooler and select different power grades of power conversion components according to battery pack capacity and vehicle load tonnage. The split modular design of Custom BTMS Set avoids clients’ high cost of re-opening molds for small-batch prototype testing, lowering the R&D threshold for emerging Indonesian electric heavy truck brands.
The power conversion equipment supporting the liquid cooling circulation system needs to output stable high current for heavy truck large-capacity battery packs, so Newbase matches each set of Humidity Adapted BTMS with self-produced High Flow DC Converter. This converter supports high-current continuous output, and adds waterproof and moisture-proof circuit protection to adapt to rainy and humid island driving conditions. Stable power output ensures the long-term continuous operation of the whole set of Archipelagic Liquid Cooling circulation system during cross-island multi-day freight transportation.
Newbase’s Southeast Asian regional technical team provides remote parameter debugging service for clients purchasing batches of Custom BTMS Set. When local vehicle manufacturers assemble electric heavy trucks, engineers can adjust the operating logic of Truck Battery Cooler and the output power of High Flow DC Converter according to the humidity and temperature characteristics of different Indonesian islands, realizing fast product adaptation without long offline cycle testing. A major electric heavy truck OEM factory in Surabaya has reached long-term bulk supply cooperation with Newbase, purchasing large quantities of integrated liquid cooling kits including standard Humidity Adapted BTMS and matched High Flow DC Converter.
Market forecast shows Indonesia’s heavy-duty commercial vehicle BTMS market will maintain a CAGR of 13.5% in the next five years, driven by the government’s electric freight vehicle replacement policy. Newbase will further upgrade the condensate drainage structure of Archipelagic Liquid Cooling, optimize the heat exchange efficiency of Truck Battery Cooler, and enrich the power specification spectrum of High Flow DC Converter, continuously supplying mature and reliable Humidity Adapted BTMS and personalized Custom BTMS Set for Indonesian electric heavy truck manufacturers and logistics fleets.
