The control unit performs a first switching control when either the temperature or the output current of the in-vehicle battery detected by the detection unit is in a first abnormality range in a case where the first relay is on and the second relay is off, and performs a second switching control when the temperature of the in-vehicle battery detected by the detection unit is within the first abnormality range or within the second abnormality range after the first switching control."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection circuit for in-vehicle battery","description":"A protection circuit of an in-vehicle battery has a detection unit that detects at least the temperature of the in-vehicle battery, and a control unit that controls a first relay and a second relay.
