The On-board Charger model family is designed around a common charging platform, combining an optimized hardware platform with application-specific software tuning to support multiple equipment platforms. Configurable charging parameters help reduce charger variants and simplify product development, while efficient power conversion and CAN, UART, and BLE communication options support reliable performance and system integration.
The fully potted internal structure helps absorb vibration and protect critical electronic components during daily vehicle operation. Combined with the industrial-grade aluminum housing, the charger is designed to withstand vibration, dust, moisture, and demanding outdoor environments. The sealed structure also supports IP67 waterproof protection for enhanced durability and reliability.
The On-board Charger is designed for direct integration into electric vehicles and industrial equipment, combining flexible system interfaces, robust protection, and adaptable charging control for demanding applications.
LLC + SR architecture reduces switching and conduction losses, improving power conversion efficiency and supporting stable high-power operation.
An aluminum housing combined with balanced passive and active cooling improves heat dissipation and keeps surface temperature rise within 30°C.
A compact internal structure with optimized fan-assisted airflow enables high power output within a space-efficient design.
A common charger supports multiple vehicle and battery configurations, with communication automatically adjusting charging parameters for different charging requirements.
Review the key technical specifications and available configurations to evaluate the charger for your application requirements.

From product development to mass production, ST Charger supports your next charging project with reliable solutions and dedicated expertise.
Dust or debris may restrict the fan from rotating. The charger’s self-cleaning function helps remove accumulated dust and restore normal fan operation.
During customization, ST Charger’s software engineers work closely with the customer’s engineering team to define and implement the required communication protocol. Charging status can be displayed through the vehicle dashboard or other external interfaces.
Built-in protection logic and fault alerts enhance system safety, while intelligent adjustment of charging voltage and current helps the charger adapt to different system and battery requirements within its designed operating range.
Adequate airflow and clearance around the charger are required for proper heat dissipation. Keep the charger away from heat-sensitive wires, plastics, and other materials that could melt or cause a short circuit.
