The governments of India and Bangladesh have released successive policies to promote electric commercial vehicles to cut fuel import costs and carbon emissions. Thousands of electric heavy trucks for intercity freight and light electric delivery vans for urban distribution have been put into operation across the two countries. However, long-term high-temperature operation brings severe hidden dangers to lithium battery packs: uneven heat accumulation leads to shortened battery cycle life, reduced driving range and even thermal runaway risks. To solve this core pain point for South Asian EV manufacturers and fleet owners, Newbase launches the tailor-made High Temp BTMS for tropical high-temperature working scenarios.
Ordinary air-cooled battery cooling systems cannot balance temperature difference of battery modules under 42℃ continuous ambient temperature, while the core design of High Temp BTMS is full-surrounding Tropical Liquid Cooling circulation pipeline. Water-glycol coolant flows evenly through every battery unit, controlling the overall temperature fluctuation within ±2℃ during full-load driving. Multiple local test fleets in Mumbai and Dhaka fed back that installing High Temp BTMS extends the single-charge driving range of electric trucks by 17%, and reduces annual battery replacement cost by nearly 40%, greatly improving the total operation income of logistics companies.
For small-scale local EV assembly factories without independent thermal management R&D capability, Newbase provides modularized Custom BTMS Module with flexible parameter adjustment space. Clients can modify pipeline layout, cooling flow rate and communication protocol of the Custom BTMS Module to match self-developed truck and van chassis. The modular design avoids repeated mold opening costs for small batch prototype orders, lowering the R&D threshold for emerging South Asian EV brands. Every set of Custom BTMS Module is equipped with supporting EV Battery Cooler, which strengthens heat exchange efficiency for battery bottom plates under high-temperature exposure.
The power conversion link between vehicle power battery and BTMS cooling system directly affects overall energy consumption, so Newbase matches each set of liquid cooling equipment with self-produced Efficient DC Converter. This converter minimizes power loss during voltage conversion, and can stably operate under unstable grid voltage common in rural areas of Bangladesh and remote Indian towns. The stable output of Efficient DC Converter ensures continuous operation of the whole set of Tropical Liquid Cooling system even when vehicles are charged outdoors under blazing sun.
Newbase’s South Asian technical support team provides one-stop debugging service for clients purchasing High Temp BTMS and supporting accessories. When local EV manufacturers install batches of Custom BTMS Module, engineers can remotely adjust the operation logic of EV Battery Cooler and Efficient DC Converter according to local climate characteristics, realizing fast product adaptation without long offline testing cycles. A major electric truck OEM in New Delhi has reached long-term cooperation with Newbase, purchasing large quantities of integrated liquid cooling kits including High Temp BTMS and matched Efficient DC Converter for its 2027 new vehicle lineup.
Market research predicts that the South Asian electric commercial vehicle BTMS market will grow at a CAGR of 13.2% in the next five years, driven by large-scale electrification of urban delivery fleets and intercity heavy-duty freight vehicles. Newbase will further optimize the anti-high-temperature material of EV Battery Cooler, upgrade the circulation efficiency of Tropical Liquid Cooling, and continuously launch cost-effective Custom BTMS Module, consolidating its market share of professional High Temp BTMS supplier in India and Bangladesh.
