The embodiment of the invention provides a voltage and temperature acquisition device, a battery module system and an electric vehicle. The voltage and temperature acquisition device comprises a hardboard substrate, a tin plating layer and a first connector. The connection between the hard board substrate and a battery management system is realized through the first connector arranged on the hardboard substrate, and the first connector is further connected with the tin plating layer covering the hard board substrate through a hard board sampling line, so that the first connector can be electrically connected with a battery module and a temperature sensor, and the battery management system receives the voltage and the temperature, which are acquired by the voltage and temperature acquisition device, of the battery module. The voltage and temperature acquisition device adopting the hard board substrate structure has the advantages of small size and light weight, and can avoid errors ofthe acquired data due to incorrect wire connection.
Description
technical field [0001] The present application relates to the field of new energy batteries, and in particular, to a voltage and temperature acquisition device, a battery module system, and an electric vehicle. Background technique [0002] New energy vehicles are currently a hot spot of research and development in various countries. Compared with traditional fuel vehicles, the development of electric vehicles can effectively relieve the pressure of depletion of fossil energy, and also help to reduce the emission of carbon dioxide and other sulfur-containing gases. [0003] In order to better manage the battery module, the voltage and temperature of the battery module need to be collected and transmitted to the battery management system. At present, wires are usually used to connect the battery management system to the cells of the battery module, so as to transmit the voltage and temperature data of the battery module to the battery management system. The volume is large,...
