Axiom Energy Conversion, a long-established leader in India’s EV power electronics sector, has announced the launch of its next-generation on-board charger (OBC) portfolio designed to support the expanding needs of electric two-wheelers, three-wheelers, and compact commercial EVs. The new lineup features four models, the ONB 080, ONB 150, ONB 200 and ONB 300, each engineered to deliver superior efficiency, rugged reliability, and seamless integration with modern EV platforms.
Axiom’s latest chargers mark a significant advancement in India’s on-board charging technology. Each model operates across a wide AC input range of 150 VAC to 270 VAC, enabling stable charging even under the fluctuating grid conditions that are common across several regions of the country. With peak efficiencies exceeding 93% and power factors approaching 0.98, the chargers are designed to minimize energy loss and reduce thermal stress on vehicle electronics.
All four chargers are powered by an advanced LLC resonant converter architecture combined with active power-factor correction. This allows soft-switching operation, reduced electromagnetic noise, and enhanced thermal performance. The ONB 300 series, Axiom’s flagship variant, comes in a fully sealed IP67 enclosure that protects against dust, water, and harsh environmental exposure. It is also capable of operating from –40°C to +60°C, making it suitable for real-world applications ranging from monsoon roads to high-temperature delivery cycles.
A major highlight of the new OBC platform is its CAN-based communication interface. This feature enables real-time interaction with the vehicle control system, allowing functions such as remote diagnostics, smart charging control, adaptive thermal management, and over-the-air firmware upgrades. The chargers also come with a comprehensive suite of protections, including over-voltage, over-current, under-voltage, short-circuit, reverse polarity, reverse current, and temperature-based shutdown with automatic recovery. All models comply with major automotive reliability standards, including ISO 16750, which covers vibration, thermal endurance, and electrical robustness.
The ONB 080, ONB 150, ONB 200, and ONB 300 series support a wide range of popular EV battery voltages, including 48 V, 60 V, 72 V and even higher-voltage platforms up to 110 V, depending on the model. With output currents ranging between 10 A and 40 A, these chargers are suitable for lightweight scooters, high-performance motorcycles, cargo three-wheelers, and compact LCV-class EVs.
Speaking on the launch, Mr. M. J. Purohit, CEO of Axiom Energy, said that the new OBC lineup represents years of continuous investment in R&D and a strong commitment to supporting India’s EV transition. “These chargers are not only efficient but are engineered from the ground up for Indian operating conditions. The combination of rugged design, sealed construction, and intelligent communication capabilities sets a new benchmark for reliability in the segment,” he said.
Mr. Vijay Patel, Director of Engineering, added that OEMs will particularly benefit from the modularity and integration flexibility offered by the new series. “We wanted to build a platform that is future-ready. Whether it is CAN communication, adaptive charging algorithms, or thermal resilience, every aspect of the design has been optimized for next-generation EV architectures,” he noted.
Axiom Energy operates two high-capacity manufacturing facilities in Hyderabad, including one dedicated to sealed IP67-rated chargers. With a production capability of several million units annually, the company supports large OEM programs and the rapidly scaling EV ecosystem in India. A well-established nationwide service and technical support infrastructure further strengthens Axiom’s value proposition for vehicle manufacturers and fleet operators.
