Classification by Battery Orientation
Vertical: Batteries are placed upright; this minimizes the footprint on the baseplate and suits products with limited bottom-side space.
Horizontal: Batteries are laid flat; this lowers the center of gravity and is commonly used in large-scale equipment.
Handheld/Remote-Operated: Separated from the main unit and connected via a long cable, allowing for convenient handheld control of start/stop functions.
Classification by New Energy Vehicle (NEV) Structure
Frame-based: A metal frame secures groups of battery cells; this facilitates maintenance but results in lower energy density.
Modular: Integrates standardized modules to balance safety and energy density; currently the mainstream solution.
Integrated (Cell-to-Pack): Eliminates independent modules in favor of a compact cell arrangement; increases volumetric efficiency by over 20% and is often used in high-end models.
Classification by Application Scenario
Energy Storage Battery Enclosures: Prioritize high capacity and long cycle life; suitable for photovoltaic power plants and grid peak-shaving applications.
Explosion-proof Battery Enclosures: Feature reinforced sealing and flame-retardant designs; suitable for environments with flammable or explosive hazards, such as mines and chemical plants.
Custom/Non-standard Battery Enclosures: Developed for unique spatial constraints or extreme temperature and humidity conditions to meet specific installation requirements.
Classification by Material
Steel: High strength and low cost, but relatively poor corrosion resistance.
Aluminum Alloy: Lightweight and corrosion-resistant; widely used in new energy vehicles.
Fiberglass (FRP): Offers excellent thermal insulation and corrosion resistance, though the enclosure itself is relatively heavy.
