Battery swapping method for electric vehicles that reduces the size and complexity of battery swap stations by avoiding the need to rotate the battery packs. The method involves using a specialized overturning mechanism to move the battery packs between the vehicle and charging compartment without rotating them. The mechanism has two perpendicular sections that hold the packs at different positions. The packs are moved between the sections without flipping. This allows vertical transfer of packs without requiring a large rotating area.

Shared battery swapping method for electric vehicles that allows efficient and safe battery replacement in public charging infrastructure. The method involves a shared battery swapping device that matches users' batteries with suppliers based on data. When a user inserts a battery, the device sends the info to the corresponding supplier. The supplier then sends back charging or swapping instructions. The device follows the instructions to charge or swap the battery. After completion, charging/swapping data is fed back to the supplier. This allows suppliers to manage and maintain batteries based on usage.

Improving electric vehicle range, charging time, and station availability by using modular batteries that can be easily swapped out like in a vending machine. The electric vehicle has a removable battery module system accessible through an exterior panel. When the battery charge gets low, the vehicle goes to a vending station to swap out the depleted module for a charged one. The vending station has a robotic arm to automate the process. This allows quick, convenient charging without waiting for slow charging times or finding an open station. The modular design enables using existing engine compartments for battery storage. The vehicle body has a support structure to hold the modules. They can slide in and out for replacement.

Modular battery exchange system that allows scaling of battery replacement capacity at a battery exchange station after initial deployment. The system uses detachable, modular battery charging modules that can be added or removed from a station as demand changes. Each module has a tray to guide and hold a battery, a power terminal to charge it, a communication terminal for battery management, and an indicator to show charge level. The modules are detachable and can be easily swapped to expand or contract the number of batteries in a station without replacing the entire unit.

Hot-swap battery module that can be inserted into a battery pack without worrying about voltage mismatch. The module has switches, transistors, and circuitry to manage charging, discharging, and voltage levels. When a new module is inserted, it starts in a low-current discharge mode to prevent reverse charging. If the pack voltage is normal, it soft starts charging. If the pack voltage is low, it provides a controlled discharge to match pack voltage. If the pack voltage is very low, it disconnects. This allows hot-swapping without voltage mismatch issues.
