Market Demand for High-Power Chargers with Aluminum Shells

The market demand for high-power chargers with aluminum shells has grown significantly in recent years, mainly driven by strong demand from new energy vehicles, energy storage systems, consumer electronics, and industrial automation.

Demand for On-Board Chargers (OBCs) is surging: With the continued rise in sales of new energy vehicles (estimated to reach 11.5 million units in 2026), each vehicle requires an average of 4-6 aluminum-cased transformers or charging modules, creating a market exceeding 10 billion yuan in demand alone.

The 800V high-voltage architecture is rapidly penetrating the market: Sales of new vehicles equipped with 800V platforms reached 3.174 million units in 2025, driving demand for high-power, high-efficiency chargers. Aluminum casings, due to their lightweight and high thermal conductivity, have become the preferred packaging material.

The construction of public charging stations is accelerating: The National Energy Administration plans to build over 200,000 public charging stations by 2026, leading to a surge in demand for commercial-grade high-power liquid-cooled charging module casings, with a unit price 3.8 times that of ordinary household casings.

Intelligent equipment such as AGVs and inspection robots: High-power wireless charging devices supporting a 30mm wireless charging distance are already used in logistics robots and service robots. Their transmitters generally use aluminum alloy shells for both heat dissipation and protection.

Medium and heavy-duty vehicles such as electric tricycles, sanitation vehicles, and forklifts: Manufacturers such as Hengjunfeng Technology have launched 48V~84V series aluminum-shell high-power fast charging chargers, featuring waterproofing, pulse repair, and automatic shutdown upon full charge.

Power systems and industrial equipment: The IIT2000 series industrial battery chargers are widely used in electric motorcycles, electric yachts, and aerial work platforms. They use die-cast aluminum shells with an IP67 protection rating, adapting to complex environments.
