Xa iqondo lobushushu lasebusika liphantsi kakhulu, ibhetri yezithuthi zombane ziya kwaphulwa ubomi (ukubola komthamo), buthathaka (ukubola kokusebenza), ukuba ngeli xesha ukutshaja kuya kubeka ingozi efihlakeleyo yokufa okunobundlobongela (imvula ye-lithium ebangelwa umngcipheko wesiphaluka esifutshane sangaphakathi. ukubaleka kwe-thermal).Ngoko ke, xa iqondo lokushisa liphantsi kakhulu, kuyimfuneko ukutshisa (okanye ukugquma).Isifudumezi esipholisayo se-ThePTC sisetyenziselwa ukufudumeza indawo yabakhweli, kunye nokususa iqhwa kunye nokugrumba iifestile, okanye ibhetri yamandla olawulo lobushushu bebhetri.
