Under high-frequency battery swapping and complex operating conditions, a power battery must not only “run steadily,” but also “last longer.” As a national high-tech enterprise with over a decade of expertise in lithium batteries, Hailei New Energy delivers end-to-end capabilities across R&D, design, manufacturing, and delivery. From raw material selection and active BMS balancing to coordinated PACK structural optimization, we have built a closed-loop engineering system.

This structural upgrade combines a die-cast upper cover + one-piece deep-drawn lower housing + dual-shell buffering to enhance strength and vibration resistance. Together with a hardware-based thermal conduction path and a dedicated BMS cooling module for rapid temperature reduction, it helps mitigate thermal aging—delivering a power battery solution that is safer, more stable, and longer-lasting.

Structural Upgrade: Stronger, More Stable

· Die-cast aluminum alloy upper cover: High strength, corrosion resistance, and improved deformation resistance

· One-piece deep-drawn lower housing: Seamless forming for higher impact resistance and crack prevention

· Dual-shell buffered structure: Dual-layer protection to significantly enhance module structural strength

Thermal Management: Faster Cooling, Slower Aging

· Balanced heat distribution: Semiconductor thermal material integrated at the bottom helps equalize cell heat

· Efficient BMS cooling: Flat MOS heat sink + thermally conductive silicone pads enable rapid temperature reduction through the cooling module

Safety is built into the structure, and longevity is driven by thermal control. From battery swapping operations to two-wheeler applications, Hailei New Energy safeguards every journey—every time you set off.
