BATTERY FOR ELECTRIC VEHICLE WITH PARALLEL CONNECTION Russian patent published in 2023 - IPC H01M10/02 H01M50/298 H01M50/503 H01M50/509 H01M50/543 B60L50/60 

FIELD: electric vehicles.

SUBSTANCE: invention relates to a battery with a parallel connection for an electric vehicle. The battery pack is formed by connecting battery cells in parallel and in series. The block consists of batteries, which are the minimum unit for powering an electric vehicle, and a set of additionally connected batteries. The battery connected in parallel for an electric vehicle is designed to increase the overall capacity. A protective device is provided for each set of batteries. The safety device of all battery packs is a combination battery pack with parallel connection. The combo battery pack can be controlled by one common power management system (BMS). The number of common power management system (BMS) signal terminals installed in individual battery strings is m. When the maximum number of connected battery pack is n, for n×m signal terminals, connect to the first battery pack through the first signal cable. The remaining terminals of the connector not connected to the signal terminal of the first set of batteries are connected to the signal terminal of the second set of batteries through the second signal cable.

EFFECT: increase in safety is achieved with a parallel increase in battery capacity.
