This paper takes non-road mobile machinery power lithium battery as the research object,focuses on the two key links of low temperature heating and high temperature heat dissipation of power battery,and carries out the de-sign and research of power battery temperature integrated control system.In view of the impact of temperature on battery performance and life,this paper adopts the extrusion molding of aluminum profile liquid cooling plate,long circular cool-ing liquid channel cross-section,parallel arrangement at the bottom and side of the module,to achieve multi-directional cooling of the battery module.At the same time,the resistance heating plateisinstalledon both sides of the battery mod-ule,which can make the battery quickly heat up to the appropriate temperature at low temperature,and ensure the good charge and discharge performance of the power battery.The power battery temperature integrated control system can ef-fectively solve the problem of large temperature difference between the battery module and the single cell,and provide a strong guarantee for the safe and efficient work of the power battery.
