200A Energy-Efficient Off-Board Charger

Our products feature IP41 protection, high-efficiency fast charging and lightweight design. They are widely applied in electric forklifts, pallet trucks, stackers and industrial cleaning equipment, with a charging efficiency of over 94%. Our products are exported worldwide and serve as a reliable partner for industrial charging solutions.

The 200A Energy-Efficient Off-Board Charger is a high-power independent charging device installed separately from the equipment. It converts three-phase AC power into stable DC power to deliver efficient, safe and fast charging for power batteries in electric forklifts, warehouse handling vehicles and other industrial machinery, acting as a professional “energy supply station” for industrial vehicles.

Adopting an intelligent charging algorithm, the charger accurately adjusts charging parameters to realize constant-current and constant-voltage (CC/CV) charging. It ensures high charging efficiency while effectively protecting battery lifespan, making it a core supporting device for modern logistics, warehousing and manufacturing industries.

Key Advantages

Adopting high-frequency soft-switching technology and active PFC design, the charger achieves a charging efficiency of ≥94% in high-frequency forklift operation. It reduces charging time by 30% compared with traditional chargers and saves more than 800 kWh of electricity per unit per year.

For complex working conditions such as outdoor cleaning equipment and port handling vehicles, the charger adopts an IP41 dustproof and waterproof structure to resist dust and rain erosion. The lightweight aluminum alloy body weighs only 60 kg, 15% lighter than similar products, making movement and installation more convenient.

With a wide operating temperature range of -20℃~50℃, it meets the demands of stackers and other equipment in extreme environments. Equipped with standard BMS communication, it matches battery status in real time, prevents overcharging, overvoltage and overheating, extends battery life by 30%, and combines energy saving and high reliability.
