In　recent　years,　heat　storage　system　combining　sensible　and　latent　heat　materials　has　received　more　and　more　attentions.　In　this　paper,　we　proposed　the　hybrid　configuration　with　a　macro-encapsulation,　and　analyzed　its　charging　performance　with　different　influencing　factors　by　CFD　simulation.　In　the　case,　the　sensible　heat　storage　materials　are　magnesia　brick　or　HT　concrete　and　the　phase　change　materials　(PCMs)　are　mixed　molten　salts.　Firstly,　we　analyzed　the　heat　transfer　characteristics　of　the　hybrid　configuration　in　charging　process.　Then,　we　analyzed　the　effect　of　heating　power　on　charging　performance.　The　maximum　temperature　of　the　heating　surface　shall　not　exceed　500　degrees　C　as　the　constraint　condition,　the　heat　storage　capacity　increases　at　first　and　then　decreases　with　the　heating　power.　Then,　we　compared　the　charging　performance　of　different　solid　structure　and　the　hybrid　configurations.　Whether　magnesia　brick　or　HT　concrete,　the　charging　performance　of　the　solid　structure　is　better　than　that　of　the　hybrid　configuration,　because　the　thermal　conductivity　of　the　molten　salt　is　significantly　lower　than　that　of　the　two　sensible　heat　storage　materials.　Then,　we　compared　the　charging　performance　of　different　molten　salts.　The　hybrid　configuration　with　lower　melting　point　molten　salt　has　better　performance　because　of　more　intensity　natural　convection.　Finally,　we　analyzed　the　charging　performance　of　the　hybrid　configuration　used　the　composite　phase　change　material　(CPCM)　with　high　thermal　conductivity　and　specific　heat.　From　the　result,　the　charging　performance　increases　by　22.5%　compared　with　the　solid　structure.　These　results　indicate　that　the　hybrid　configuration　with　the　macro-encapsulation　method　is　a　potential　form　of　thermal　energy　storage,　but　it　needs　to　be　further　optimized.
