The invention relates to the technical field of vehicles, in particular to a battery monitoring unit, a battery pack and a vehicle, and aims to solve the problems that in the prior art, a battery monitoring unit is thick and can only be installed on the bottom wall of a box body, the structural space is not compact, large waste exists, and the energy density of the battery pack is low. In order to achieve the purpose, the battery monitoring unit comprises a first shell, a second shell and a circuit board, the first shell is fixedly connected with the second shell, the circuit board is fixed between the first shell and the second shell, a plurality of pits are formed in the surface of the first shell, and the second shell is fixedly connected with the circuit board. Structural adhesive is coated between the circuit board and the first shell. According to the battery monitoring unit, the concave pit is formed in the first shell, the bending rigidity of the first shell can be improved, the circuit board and the first shell are bonded through the structural adhesive, the connection between the circuit board and the first shell is enhanced, the overall strength of the battery monitoring unit can be improved, and therefore the whole battery monitoring unit can meet the mechanical property requirement.
本发明涉及车辆技术领域,具体提供一种电池监控单元、电池包及车辆,旨在解决现有技术中电池监控单元厚度较厚只能安装在箱体的底壁上,结构空间不紧凑存在较大的浪费,导致电池包能量密度低的问题。为此目的,本发明的电池监控单元包括第一壳体、第二壳体和电路板,所述第一壳体与所述第二壳体固定连接,所述电路板固定在所述第一壳体和所述第二壳体之间,所述第一壳体的表面上设有多个凹坑,所述电路板与第一壳体之间涂有结构胶。本发明在第一壳体上设置凹坑,有助于提高第一壳体的弯曲刚度,将电路板与第一壳体通过结构胶粘结,增强了电路板与第一壳体的连接,有利于提高电池监控单元的整体强度,从而使电池监控单元整体满足力学性能要求。
