Disclosed is a method for manufacturing a separator for an electrochemical device. The method for manufacturing a separator uses polyvinyl pyrrolidone (PVP) functioning as a dispersing agent, and thus provides high dispersibility of particles and prevents aggregation of particles, even when inorganic particles having a small particle diameter is used in slurry for forming a porous coating layer. Therefore, the inorganic particles are distributed homogeneously in the porous coating layer of a finished separator. In addition, since PVP is used in combination with a fluorinated binder resin as a binder resin for the porous coating layer, the separator shows improved peel strength and adhesion to an electrode. Further, a non-solvent ingredient for the fluorinated binder resin is used as a solvent for PVP, and a non-solvent ingredient for PVP is used as a solvent for the fluorinated binder resin. As a result, while the porous coating layer is dried under a humidified condition, phase separation ...

A battery management system according to the present disclosure includes a current sensor to measure a battery current which is an electric current flowing through a battery, a voltage sensor to measure a battery voltage which is a voltage across the battery, and a control circuit. When the control circuit receives a key-on signal during a first rest period of the battery, the control circuit determines a fixed rest time, a fixed Open Circuit Voltage (OCV) and a fixed State Of Charge (SOC), and determines an integrated current value of the battery current during a cycle period of the battery. When the control circuit receives a key-off signal during the cycle period, the control circuit starts a second rest period of the battery. The control circuit determines an interest SOC corresponding to an interest OCV which is the battery voltage during the second rest period. The control circuit determines a State Of Heath (SOH) of the battery based on the fixed SOC, the integrated current value ...
