Bangladesh presents a unique electrification landscape characterized by high urban traffic density, expanding rural mobility, monsoon floods, and voltage instability. Our onboard chargers are custom-engineered to meet these specific operational demands.
Over 1.5 million electric 3-wheelers (Easy-bikes and Auto-rickshaws) operate as the primary feeder transit in Dhaka, Chittagong, Sylhet, and Rajshahi. Operating on 48V, 60V, and 72V platforms, these vehicles face frequent battery deep-discharges and harsh environmental exposure.
Our die-cast aluminum 3.3kW and 1.5kW OBCs feature potted electronics that withstand extreme road vibrations and standing water during Bangladesh’s severe monsoon season, ensuring daily operational uptime for fleet operators.
Major transit fleets operating Yutong, Kinglong, Higer, and Zhongtong electric buses across key corridors (Dhaka-Chittagong Expressway) require high-power OBCs (11kW to 22kW) combined with onboard passenger amenities.
Our integrated Buspad multi-port USB chargers (QC3.0/PD3.0) directly connect to auxiliary DC lines, providing fast cabin charging while our 800V PERSINO liquid-cooled OBC units ensure ultra-fast overnight depot charging.
From luxury resorts in Cox’s Bazar and golf clubs in Kurmitola to solar-powered ferry boats navigating the Barisal and Khulna riverine networks, salt-fog corrosion and tropical humidity quickly degrade standard battery chargers.
Our VOITATOP and Smart 12V 3-Bank Marine OBCs utilize IP67/IP68 fully sealed housings with anti-corrosion anodized coatings, optimizing LiFePO4 battery life in high-salinity coastal environments.
Understanding the micro-economic and electrical grid conditions in Bangladesh is crucial for sourcing reliable EV charging hardware. Here is how our engineering overcomes key regional challenges.
The electrical grid in semi-urban and rural areas of Bangladesh often suffers from severe voltage sags (dropping below 160V AC) and sudden load-shedding spikes. Standard Western or domestic Chinese chargers calibrated strictly for 220V AC frequently trip or suffer thermal breakdown under these conditions.
Our onboard chargers feature an ultra-wide AC input range of 85V AC to 264V AC with built-in Active Power Factor Correction (PFC > 0.99). This guarantees full rated power delivery even during severe grid sags and protects internal power MOSFETs against high-voltage spikes.
The Bangladeshi EV market is rapidly undergoing a structural shift from traditional heavy lead-acid battery packs to lightweight, high-energy-density Lithium Iron Phosphate (LiFePO4) chemistry. LiFePO4 requires precision multi-stage charging algorithms (Constant Current / Constant Voltage) and active CAN bus communication with the Battery Management System (BMS).
Our OBC lineup comes pre-programmed with customizable LiFePO4 charging profiles and offers isolated CAN 2.0B protocol handshakes, preventing cell overcharging and extending lithium pack cycle life beyond 3,500 cycles.
With summer ambient temperatures regularly exceeding 40°C in Bangladeshi urban centers and high seasonal monsoon rainfall causing waterlogging, thermal dissipation and moisture sealing are mandatory engineered features.
We utilize die-cast aluminum heat sinks filled with thermally conductive silicon potting resin. This design enables full load operation up to 60°C internal cabinet temperature without power derating, while maintaining complete IP67 dust and water immersion protection.

As a leading Chinese OEM/ODM manufacturer specializing in electric vehicle power electronics, our facilities combine decades of automotive-grade manufacturing experience with strict quality control.
Our manufacturing facility spans over 25,000 square meters equipped with high-speed Yamaha and Fuji Surface Mount Technology (SMT) lines, automated optical inspection (AOI), and robotic vacuum glue-potting machinery. This ensures every solder joint and silicon seal meets rigorous automotive reliability standards.
Before shipment to Bangladesh ports, 100% of our produced chargers undergo a 4-hour full-load burn-in cycle in environmental thermal chambers ranging from -40°C to +85°C. High-voltage insulation withstand tests (HIPOT) and vibration testing guarantee zero out-of-box failures.
Our R&D engineering team consists of over 70 power electronics and software engineers. We provide turnkey custom firmware engineering to seamlessly match local Bangladeshi BMS protocols, customized charging indicator displays, and specific CAN bus speed requirements (e.g., 250kbps / 500kbps).
Technical and logistical answers compiled for local EV assemblers, B2B distributors, and fleet procurement officers in Bangladesh.
Our onboard chargers feature an intelligent active Power Factor Correction (PFC) stage built around high-grade Infineon MOSFETs and STMicroelectronics microcontrollers. This wide input circuit operates smoothly from 85V AC to 264V AC. If grid voltage drops below safe thresholds or surges unexpectedly, the internal software automatically reduces current output or safely shuts down without damaging internal components, automatically restarting once voltage stabilizes.
We offer comprehensive customization including custom DC output voltage curves (calibrated for 48V, 60V, 72V, or high-voltage LiFePO4 packs), custom mounting brackets tailored to your chassis architecture, customized wiring harness lengths, IP67 waterproof connectors (Amphenol or local standard), and branded top cover silk-screen printing with your enterprise logo.
