Embodiment Construction

[0016] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0017] figure 1 The shown monitorable lithium-ion battery module includes a housing 1 , a sensor 2 , a battery cell 3 , a bottom plate 4 , a cooling plate 5 and a PCB acquisition board 6 . The bottom plate 4 is a metal plate and is rectangular. In order to reduce the weight, the middle of the bottom plate 4 is hollowed out, and the bottom plate 4 is placed on the lowest layer of the stacked batteries 3 during installation. The housing 1 is also made of a metal plate, which is a rectangular hollow frame, figure 1 The PCB collection board 6 is placed in the hollowed out part facing the front end, and the cooling plate 5 adjacent to the side of the battery cell 3 is placed in the hollowed out place on both sides. The PCB acquisition board 6 used in this embodiment is a board integrating voltage and temperature measurement. During actua...

Abstract

The invention discloses a monitorable lithium ion battery module which comprises a shell, a sensor, battery cells, a bottom plate, radiating plates and a PCB collection plate, wherein the bottom plateis placed on the lowest layer of the stacked battery cells and is a rectangular hollow frame; the PCB collection plate is put on the front end surface; the radiating plates leaning on the side surfaces of the battery cells are arranged on the two side surfaces; the shell covers the stacked battery cells; the folded edges at four corners of the shell are propped on the bottom plate and locked by bolts. The sensor is arranged on the uppermost battery cell and then clamped with the shell, to form a structure with monitorable working conditions of battery cells and regulable clamping force in theshell. Through the structural design, circulation of the lithium ion battery module is realized in a stable clamping condition. In the charge / discharge process, lithium ions can pass through electrolyte and an isolating membrane to realize smooth disembedding. Due to the regulable clamping force, the structure is always kept in tight fit with the pole pieces, the risk of lithium precipitation inthe charge process is solved, and the cycle life and safety of the product are improved.

Description

technical field [0001] The invention relates to an electric energy storage device, in particular to a storage battery module, especially a monitorable lithium ion battery module. Background technique [0002] Lithium-ion battery is a new type of storage battery, its main performance indicators such as weight specific energy and cycle life are better than traditional lead-acid batteries. Therefore, lithium-ion batteries are widely used in data centers, mobile communication base stations, and household appliances. Since the supporting equipment of the mobile communication base station in the data center is maintained by electric energy at all times, there are high requirements for the reliability and cycle life of the supporting lithium-ion battery. In reality, the power supply of data centers and mobile base stations is composed of several lithium-ion batteries. In the battery module, the battery capacity and charge-discharge capacity of the connected batteries tend to be th...
