Abstract

The invention discloses a battery pack, a packing method of the battery pack and an electric vehicle. In the invention, the battery pack comprises more than two single batteries and also comprises electrode connecting parts, a signal processing circuit board and a central management unit, wherein the electrode connecting parts are connected between post terminals of single batteries; the signal processing circuit board is arranged at the positions of the more than two single batteries and connected with the electrode connecting parts; and the central management unit is connected with the signal processing circuit board. According to the invention, the structure of the battery pack can be more compact.

Description

technical field [0001] The invention relates to a battery pack, a method for forming the battery pack, and an electric vehicle. Background technique [0002] The power battery pack is the core component of an electric vehicle, which provides electric energy for the electric vehicle to drive the vehicle. Since the power batteries used in vehicles generally require a higher voltage level, it is often necessary to connect dozens or hundreds of battery cells in series. When the monomer capacity is small, multiple monomers need to be connected in parallel and then connected in series. In order to ensure the safe use of batteries and improve the life of battery packs, a battery management system is required to collect information such as voltage, current, and temperature of battery cells through relevant sensors, and perform state detection, safety protection, and charge and discharge control on battery cells. In addition, it is generally necessary to balance the battery cells, ...
