The invention relates to the technical field of new energy automobile electronics. The invention discloses an active damping device, a battery parallel management system and a battery parallel management method. The device comprises a thermistor, a current sampler, a control module, a heating module and a refrigeration module, and current information on a battery cluster is acquired by using the current sampler in the charging and discharging process of the battery cluster and transmitted to the control module. And the control module judges whether to output a heating signal or a refrigeratingsignal according to the current information to adjust the resistance value of the thermistor so as to adjust the current on the battery cluster to the required current. By applying the active dampingdevice provided by the invention to the battery cluster parallel system, the charging and discharging current between the parallel battery clusters can be balanced as required, the reduction of the usability of the whole battery system due to different charging and discharging currents of the battery clusters is prevented, and the service life of the whole battery system is prolonged.

    本发明涉及新能源汽车电子技术领域,公开了一种有源阻尼装置、电池并联管理系统及电池并联管理方法,包括热敏电阻、电流采样器、控制模块、发热模块和制冷模块,利用所述电流采样器在所述电池簇进行充放电的过程中对所述电池簇上的电流信息进行采集,并传输至所述控制模块。所述控制模块根据所述电流信息判断输出加热信号还是制冷信号来对所述热敏电阻的阻值进行调节,以将调节所述电池簇上的电流调整至所需要的电流。通过将本发明提供的所述有源阻尼装置应用到电池簇并联系统中,可以根据需要均衡各并联电池簇之间的充放电电流,防止因各个电池簇充放电时的电流不同,而导致降低整个电池系统可用性,延长了整个电池系统的寿命。
