NB100 Series All-in-One Integrated EV Power System | Smart 4-in-1 & 2-in-1 Controllers for Electric Buses, HVAC & Energy Storage

Product Overview

The NB100 Series All-in-One Integrated Power System represents the next generation of electrification solutions for new energy commercial vehicles, electric buses, and industrial water-cooled units. Engineered by Xinjiye Automotive Electronics, this product line consolidates multiple critical subsystems—DC-AC Inverters (VFD), Isolated DC-DC Converters, CCU (Central Control Units), and PTC Heaters—into a single, highly compact modular housing.

Available in versatile configurations including 4-in-1 Smart Control Systems (5.5kW VFD + 1.5kW DCDC + CCU + 24kW PTC) and high-power 2-in-1 Drive Solutions (15kW VFD + 3kW DCDC), the NB100 series is designed to drastically reduce wiring complexity, save installation space, and lower total system costs. With robust IP67 protection, natural convection cooling options for silent operation, and wide voltage input ranges (400V-850V), these units are the ideal choice for powering electric air conditioning compressors, traction motors, auxiliary batteries, and cabin heating systems in harsh global environments.

Key Features & Advantages

• Ultimate Integration (Up to 4-in-1): Seamlessly integrates DCDC conversion, AC motor driving (VFD), intelligent logic control (CCU), and high-power PTC heating. This reduces component count by up to 75% compared to discrete systems, simplifying vehicle architecture and maintenance.
• Advanced Modular Design: Built with independent functional modules (DCDC, Inverter, CCU, PTC) within a unified chassis. This ensures high reliability, efficient thermal management, and scalability for different power requirements (from 1.5kW to 15kW+).
• Silent Natural Cooling & IP67 Protection: Select models feature fan-less natural convection cooling, eliminating noise and mechanical failure points—perfect for urban electric buses and noise-sensitive applications. The IP67 rating guarantees dust-tight and water-immersion resistance for roof-mounted or under-chassis installations.
• Wide Voltage & High Efficiency: Supports a broad DC input range of 400V-850V (with full load capability from 450V), ensuring compatibility with various battery packs. High-efficiency conversion minimizes energy loss, extending vehicle range and reducing operating costs.
• Smart CAN Bus Communication: Equipped with integrated CCU and standard CAN 2.0B/J1939 protocols, enabling real-time data exchange with Vehicle BMS, remote diagnostics, and adaptive load management for smarter fleet operations.

Technical Specifications

Why Choose the NB100 All-in-One Series?

As the global demand for electric public transport and green logistics surges, manufacturers face increasing pressure to reduce vehicle weight, cost, and complexity. The NB100 All-in-One Series directly addresses these challenges by replacing multiple discrete boxes with a single, intelligent power hub.

• For HVAC Manufacturers: The 4-in-1 model (NB100-D-055-015-PC) is a game-changer, providing everything needed to drive the compressor, power the control system, and heat the cabin in one IP67-rated, silent unit. It is already benchmarked against industry leaders like Inovance (CV800) and validated by top-tier clients like Songz.
• For Vehicle OEMs: The 15kW 2-in-1 drives offer a robust solution for both synchronous and asynchronous motor applications, delivering high torque and efficiency while saving valuable chassis space.
• Reliability First: With modular architecture and rigorous testing (DVP validated), these units ensure maximum uptime even in extreme temperatures (-40°C to +85°C).

Whether you are developing electric city buses, intercity coaches, or stationary energy storage cooling systems, the NB100 Series provides the perfect balance of power density, intelligence, and environmental resilience.
