Abstract

The application discloses a novel structure of a paralleling network, a battery module used for configuring the paralleling network, a battery pack heating system for the battery module, and a heatingmethod for the battery module. The paralleling network is used for assembling in the battery module to connect a plurality of battery cells in parallel, the network is a conductive material that heats up after being energized, and the paralleling network comprises at least one positive connection terminal and at least one negative connection terminal. According to the paralleling network, batterymodule, battery pack heating system and battery module heating method, the battery module is directly heated by the parallel network of the battery module itself without the need of special heating component required for the battery module. The scheme is ingenious and straightforward, the structure is simple, the implementation is convenient, the module weight is not increased, and the overall cost is reduced.

Description

technical field [0001] The present application relates to a parallel network, a battery module configured with such a parallel network, a battery pack heating system for the aforementioned battery module, and a heating method for the aforementioned battery module. Background technique [0002] Lithium-ion batteries have become the focus of research due to their advantages such as high specific power, high energy density, long life, low self-discharge rate and long storage time, and gradually replace traditional lead-acid, nickel-metal hydride, nickel-cadmium and other batteries to the power battery market . As a new energy battery, lithium-ion power batteries are facing unlimited opportunities and challenges on the way to the power market. The charge and discharge capacity of lithium-ion batteries at low temperatures is attenuated, and the power performance is reduced. Below 0°C, the output performance of the lithium-ion battery is affected, and the performance of the batt...
