Abstract

The invention relates a battery module. The battery module comprises multiple single batteries, bases of the same quantity of the single batteries and a convergence circuit board, wherein each singlebattery comprises a positive electrode, a negative electrode opposite to the positive electrode, and a shell between the positive electrode and the negative electrode, the base is arranged on the convergence circuit board and each base is internally provided with an electric connecting piece, the convergence circuit board comprises multiple secondary unit boards, each secondary unit board comprises a positive convergence layer and a negative convergence layer, the positive convergence layer is provided with multiple elastic connecting pieces, the negative convergence layer is provided with through holes, the negative convergence layer of one of two adjacent secondary unit boards is superposed on the positive convergence layer of another secondary unit board, the elastic connecting pieces of two adjacent secondary unit boards are in one-to-one correspondence to the through holes, each single battery is sleeved outside one base correspondingly and the positive electrode is electrically connected with the elastic connecting piece, the shell is connected with a corresponding electric connecting piece in the base, and the electric connecting piece is further connected with the negativeconvergence layer.

Description

【Technical Field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a battery module. 【Background technique】 [0002] Under the pressure of the energy crisis and environmental pollution, safety, environmental protection, and energy saving have become the themes of today's automobile development. Electric vehicles have received great attention and support from the transportation and energy departments due to their advantages in energy saving, environmental protection and non-polluting. In recent years, The new energy automobile industry has ushered in explosive growth. The existing battery cell confluence mainly uses bolt connection and welding to fix the battery core on the copper plate, and realizes the series-parallel connection between the batteries through a large number of wiring harnesses and complex circuits. Such a confluence method has complicated circuit structure, excessive wiring harness, poor reliability, complicated installa...
