In　view　of　the　significant　decline　in　the　driving　range　of　battery　electric　vehicle　during　heating　in　winter,　a　new　method　for　efficient　utilization　of　braking　energy　is　proposed.　A　new　type　of　eddy-current　retarding　&　heating　system　for　electric　bus　is　designed.　Through　the　studies　on　the　braking　stability　of　electro-mechanic-magnetic　integrated　braking　system　and　the　mechanism　of　eddy-current　retarding　and　heating,　the　braking　control　strategy　for　the　system　is　established,　and　the　simulation　and　bench　test　are　conducted　on　the　system.　The　study　provides　a　new　idea　for　enhancing　the　driving　range　and　safety　of　electric　bus.　©　2019,　Society　of　Automotive　Engineers　of　China.　All　right　reserved.
