NEWBASE Launches Next-Generation Intelligent BTMS Water-Cooled Units for Commercial EV Battery Thermal Management

As 4C and 5C ultra-fast charging become the standard for new energy commercial vehicles — turning the promise of "10-minute charge, 400 km range" into everyday reality — battery thermal management systems are facing unprecedented challenges. Heat dissipation demands are growing exponentially, temperature control precision must shift from degree-level to sub-degree accuracy, and system response times need to leap from seconds to milliseconds.

Zhengzhou, China — NEWBASE (Zhengzhou NEWBASE Automotive Electronics Co., Ltd.), the only domestic company with full-stack self-developed underlying control technology for new energy thermal management systems, has officially released its next-generation intelligent BTMS (Battery Thermal Management System) water-cooled unit lineup. This is not a simple product iteration — it represents a paradigm shift from passive cooling to proactive intelligent control in commercial vehicle thermal management.

Three Manufacturing Bases, Full-Chain Capability

NEWBASE operates three R&D and production bases across Zhengzhou, Jiaozuo, and Huangshan, covering a total area of 40,000 square meters. The company has built a complete industrial chain for new energy thermal management systems — from research and development through manufacturing to after-sales service.

The dedicated BTMS production line adopts a flexible manufacturing model, supporting multi-variety, small-batch customized production. With an annual capacity of 100,000 units, NEWBASE serves the full spectrum of commercial vehicle applications including heavy trucks, light trucks, and construction machinery.

As a Ministry of Industry and Information Technology (MIIT) nationally recognized "Specialized, Refined, Differential, and Innovative" (Little Giant) enterprise, NEWBASE stands as the only company in China owning the complete proprietary control technology chain for new energy vehicle thermal management.

A Complete Product Portfolio for Every Application

The new BTMS lineup covers every commercial vehicle scenario:

The flagship BTMS-800 model delivers 8 kW of rated cooling capacity for battery packs ranging from 200 to 400 kWh, operates at DC 540V/800V, carries an IP67 protection rating, and weighs just 85 kg — all while communicating via CAN/J1939 protocols.

What This Means for the Industry

For OEMs, NEWBASE provides a complete chain of services from thermal management strategy development to calibration and validation, shortening new vehicle development cycles and reducing per-vehicle thermal management costs by 15–20% through integrated design.

For fleet operators, the benefits translate directly into operational efficiency: 50% shorter charging times in 4C fast-charging scenarios, a 30% increase in daily operating mileage, and AI-driven fault prediction that reduces unexpected downtime by 90%.

The global battery thermal management system market is projected to reach USD 13.2 billion by 2035, growing at a CAGR of 12.7%. NEWBASE is positioning itself at the forefront of this growth, particularly in the commercial vehicle segment which is expected to grow fastest due to the rapid electrification of buses, heavy-duty trucks, and delivery fleets.
