Learn More About Wuling Hongguang Charging Solutions: 96V 25A On-Board Charger (OBC) with CAN Communication
As Wuling Hongguang continues to innovate in the electric vehicle (EV) space, its charging solutions are designed to deliver reliability, efficiency, and seamless integration with modern powertrains. One key component in this ecosystem is the 96V 25A On-Board Charger (OBC), a critical system that enables convenient and intelligent AC charging for vehicles equipped with medium-voltage battery platforms. This article explores the features, technical integration, and performance of the 96V 25A OBC, with a focus on its CAN communication capability and how it supports the overall charging experience.
Overview of the 96V 25A OBC
The 96V 25A On-Board Charger is engineered to convert alternating current (AC) from standard grid power into direct current (DC) suitable for charging the vehicle’s high-voltage battery pack. With an input typically rated at 220V AC (single-phase), the OBC delivers a maximum output of 96 volts DC at 25 amps, translating to a charging power of approximately 2.4 kW. This makes it ideal for compact EVs used in urban logistics, last-mile delivery, and personal transportation—applications where Wuling Hongguang excels.
Designed for durability and efficiency, the OBC supports continuous charging with thermal management features to ensure stable performance under prolonged use. Its compact form factor and IP67-rated enclosure make it resistant to dust and water, suitable for harsh operating environments.
CAN Communication: Intelligent Charging Control
A standout feature of this OBC is its integration with CAN (Controller Area Network) communication, enabling real-time data exchange between the charger, battery management system (BMS), and vehicle control unit (VCU). This allows for:
- Smart Charging Management:The OBC receives charging profiles from the BMS, including voltage and current limits based on battery state of charge (SoC), temperature, and health.
- Fault Diagnosis and Reporting:Any anomalies—such as overvoltage, overtemperature, or communication errors—are logged and transmitted via CAN for diagnostics.
- Charging Status Monitoring:Real-time data such as charging current, voltage, SoC, and estimated time to full charge can be displayed on the dashboard or telematics system.
- Interlock and Safety Protocols:The OBC participates in vehicle-level safety routines, ensuring charging stops immediately in case of disconnection, insulation faults, or emergency shutdowns.
This level of integration ensures not only efficient charging but also enhances safety and system longevity.
Compatibility with 3-in-1 Powertrain Systems
While the provided 120kW 3-in-1 powertrain (Motor + Controller + Gearbox) operates at a higher voltage platform (385V DC), the 96V 25A OBC is typically used in lower-voltage variants of Wuling Hongguang EVs—such as those powered by LFP or lead-acid battery systems in light commercial models. These vehicles may use the OBC to charge a dedicated traction battery or support dual-battery architectures, where a smaller high-voltage pack powers auxiliary or specialized systems.
In such configurations, the OBC works in parallel with the main powertrain, ensuring the vehicle remains operational while maintaining energy efficiency. The CAN network unifies communication, allowing the OBC to coordinate charging cycles with driving readiness and energy recovery systems like regenerative braking.
