Battery Pack
High power packs need to operate over a narrower state of charge window if the power delivery is to be consistent. A long range BEV will have a very ''wide'' usable SoC of around 90 to 95%. A HEV that discharges and charges the pack in an aggressive way would need a ''narrow'' usable SoC of around 30%. Thermal Sizing. There may also be a requirement to size a battery pack …
