Vietnam’s urban last-mile delivery industry and the Philippines’ inter-island electric light truck fleets are expanding rapidly, with thousands of new electric vans and small commercial vehicles put into operation every month. The two countries’ coastal high-humidity environment leads to uneven heat accumulation inside lithium battery packs, accelerating capacity attenuation and shortening daily driving mileage, which becomes the biggest operational headache for logistics fleet operators. Newbase launches miniaturized Water Cooled BTMS optimized for light electric delivery vehicles, solving battery overheating and aging problems in coastal humid climate.
Air cooling systems commonly matched on low-cost electric vans cannot eliminate local high-temperature hot spots inside battery modules under long-time low-speed stop-and-go delivery working conditions. The closed liquid circulation loop of Water Cooled BTMS realizes uniform heat dissipation for the whole battery pack, with the built-in Van Battery Cooler closely fitting the bottom of each battery unit to transfer heat quickly. After three months of road test by a Manila coastal logistics fleet, vehicles equipped with Water Cooled BTMS gain 19% longer single-charge mileage, and the battery capacity attenuation speed slows down significantly compared with air-cooled matching schemes.
To facilitate one-stop procurement for local electric vehicle assembly factories, Newbase integrates BTMS host, cooling pipeline, temperature sensor and power conversion parts into complete packaged Coastal Thermal Kit. This integrated kit is pre-debugged before delivery, and assembly workers only need to fix the pipeline and connect the circuit to finish installation, greatly shortening the offline production cycle of electric vans. Every standard Coastal Thermal Kit contains a complete set of Water Cooled BTMS and supporting Van Battery Cooler, specially added anti-salt-fog coating to adapt to sea wind erosion in Philippine and Vietnamese coastal cities.
Many emerging local EV brands need to develop mini electric vans with different body sizes, requiring thermal management equipment to support size and power customization. Newbase provides split type Custom Cooling Module, allowing clients to freely combine cooling pipelines and heat exchange units according to battery pack layout. The R&D team can adjust the flow rate of coolant inside the Custom Cooling Module to match different battery capacities, without redesigning the whole set of Water Cooled BTMS. The flexible modular design greatly reduces the mold opening cost of small-batch prototype development for Southeast Asian vehicle manufacturers.
The power conversion unit connecting vehicle high-voltage battery and BTMS cooling system determines the overall energy utilization efficiency, so Newbase equips each set of liquid cooling equipment with self-produced Low Loss DC-DC. This converter adopts high-efficiency switching circuit design, controlling power conversion loss below 3%, far lower than ordinary DC-DC products on the market. Stable and low-loss power output ensures the continuous stable operation of Van Battery Cooler and the whole set of Custom Cooling Module even when electric vans work outdoors under high temperature and high humidity all day.
An electric vehicle OEM factory based in Hanoi has signed a long-term bulk purchase contract with Newbase, ordering large quantities of integrated Coastal Thermal Kit including standard Water Cooled BTMS and matched Low Loss DC-DC. The factory’s technical director pointed out that the detachable Custom Cooling Module can adapt to multiple battery pack layouts of their mini delivery van series, bringing great flexibility to new product development.
Market analysis predicts the Southeast Asian light commercial vehicle BTMS market will maintain high-speed growth in the next five years, as e-commerce last-mile delivery demand continuously rises in Vietnam, Thailand and the Philippines. Newbase will keep optimizing the heat exchange efficiency of Van Battery Cooler, reduce the production cost of Low Loss DC-DC, and upgrade the anti-humidity performance of the whole set of Coastal Thermal Kit, continuously supplying mature and reliable Water Cooled BTMS and customized Custom Cooling Module for regional electric vehicle manufacturers and logistics fleets.
