The '''HB-E220 series''' ({{langx|ja|HB-E220系}}) is a [[Hybrid train|hybrid]] [[diesel multiple unit]] (DMU) train type operated by [[East Japan Railway Company]] (JR East) on services in the Takasaki and Morioka areas of Japan. 32 vehicles are to be built to replace ageing [[KiHa 100 series]] and [[KiHa 110 series]] DMUs.<ref>{{cite web |title=キハ100・110系の置き換え用！高崎・盛岡エリアに新型HB-E220系が導入！ |trans-title=To replace the KiHa 100 and 110 series!

== Design == The HB-E220 series adopts a traction system similar to that of the diesel–electric [[GV-E400 series]], but the HB-E220 series also features onboard batteries. The diesel engine and batteries can operate alone or together to provide power to the train's main converter, which controls its traction motors.<ref name="Mynavi22082025"/> When braking, the traction motors act as generators, recharging the batteries.<ref>{{Cite web |date=2025-05-15 |title= |script-title=ja:【釜石線、八高線などに投入】ハイブリッド方式のHB-E220系、お披露目！ |trans-title=(Introduced on the Kamaishi Line, Hachiko Line, etc.) Hybrid HB-E220 series unveiled! |url=https://rail.hobidas.com/feature/518257/ |access-date=2025-05-23 |website=RM News |publisher=Neko Publishing |language=ja |publication-place=Japan}}</ref>
