【Abstract】In order to solve the problem of low-voltage battery feeding caused by long-term parking of hybrid electricvehicles，this paperdesignedanintelligentcharging methodforlow-voltagebatteriesofnew energy hybrid electric vehicles.This paper introduced thesystem strategyofthe intelligent charging methodandthecontrollogic of each controler involved.This functional solution has been verifiedonreal vehicles.The vehicle testresults show that afterdetecting thesmall batteryfeeding，theintellgent powerreplenishmentfunction wasactivated tostartrecharging. Afterreachingthe intelligent powerreplenishmentexitcondition，the vehicleturned tothesleepstateagain.Theresults indicatedthattheintellgent powerreplenishmentsystem methoddesigned inthisarticlecould effectivelyreplenishthe low-voltage battery power inthe vehicle's sleep state，and solve the problem of low-voltage battery feeding.
