With the rapid growth of the new energy sector, charging methods have become a key focus for many vehicle owners and operators. Battery swapping stations, as an efficient and convenient charging solution, are gradually coming into the public eye. Among these, under-chassis and overhead battery swapping stations are the two mainstream types, each with its own unique operating principles and suitable applications. Today, we will take a detailed look at these two types of swapping stations from the perspective of their operating principles and processes, to help you identify the solution that best meets your needs.

Chassis-mounted Battery Swap Stations: The ‘Efficiency Choice’ for Passenger Cars and Light Commercial Vehicles

Chassis-based battery swapping, as the name suggests, involves removing the original battery from beneath the vehicle’s chassis and replacing it with a fully charged one. The operating principle is ingenious: as the vehicle slowly drives into the swapping station, a series of automated devices begin to work in concert.The RGV robot moves nimbly along the tracks like a precise dancer, positioning itself accurately beneath the vehicle; specialised unlocking and removal equipment then swiftly springs into action, unlocking and removing the original battery, before immediately installing the fully charged battery, completing the locking and inspection process. The entire procedure requires no manual intervention and can be completed in 2–3 minutes, with efficiency comparable to refuelling a petrol vehicle.

The greatest advantage of the underfloor battery swap station lies in its high compatibility and relatively compact footprint, making it suitable for over 95% of passenger cars and light commercial vehicles, including saloons, SUVs, MPVs and light delivery vans. Its automated operation not only boosts efficiency but also enables centralised battery management and maintenance through the ‘separation of vehicle and battery’, extending battery life whilst reducing the vehicle purchase cost for users.

In practical application, for urban commuters, time is of the essence. The rapid and convenient battery swapping service offered by chassis-mounted stations can significantly reduce recharging time, making journeys smoother. For operators of light commercial vehicles, efficient battery swapping translates to higher transport efficiency and lower operating costs, enabling them to gain a competitive edge in a fiercely competitive market.

Overhead-mounted battery swap stations: the ultimate solution for heavy-duty vehicles such as lorries

The core feature of overhead battery swap stations lies in their unique operating method. Unlike chassis-mounted stations, overhead stations employ a ‘top-down’ approach, utilising mechanical devices such as gantry robots positioned above the vehicle to perform battery retrieval, replacement and storage operations.When heavy-duty vehicles such as heavy-duty lorries or mining trucks enter the swapping station, the gantry robot acts like a giant of immense strength, steadily extending its ‘arm’ to precisely grasp the battery above the vehicle and replace it with a fully charged one. Designed specifically for the structural characteristics and operational scenarios of heavy-duty vehicles, it is essential equipment for long-haul logistics and enclosed environments.

The core component of the overhead battery swap station is the gantry robot positioned above the vehicle. This mechanical device possesses a formidable load-bearing capacity, enabling it to precisely grasp the large battery packs found in heavy-duty trucks and mining trucks.During operation, once the vehicle has come to a complete stop, the system automatically identifies the battery’s position. The gantry robot then uses intelligent navigation to grasp and transfer the battery, moving the depleted unit to the charging area whilst simultaneously hoisting the fully charged battery into the vehicle’s battery compartment and securing it in place. The entire process can be completed within five minutes, meeting the operational requirements of heavy-duty vehicles for ‘short stops and long runs’.The advantages of the overhead hoist-type battery swap station lie in two key areas: ‘heavy-duty compatibility’ and ‘environmental resilience’. Its mechanical structure can support the immense weight of heavy-duty truck batteries, whilst its high protection rating ensures stable operation in dusty, bumpy and enclosed environments such as ports, mines and long-haul logistics routes.
