  "text": "The high efficient alternator leads to the saved mechanical power which is to be calculated in two steps. In the first step the saved mechanical power is to be calculated under ‘real world’ conditions. The second step is to calculate the saved mechanical power under type approval conditions. Subtracting these 2 mechanical power savings is to result in the accountable share of the saved mechanical power.\nThe saved mechanical power under ‘real world’ conditions is to be calculated with formula (6).\nFormula (6) ΔΡ m − RW = P RW ∕ η Α − P RW ∕ η Α − EI\nWhere:\nΔΡm–RW Saved mechanical power under real world conditions (W);\nPRW Electric power under real world conditions, which is 750 W;\nηΑ Efficiency of the baseline alternator;\nηΑ–EI Efficiency of the high efficient alternator\nThe saved mechanical power under type-approval conditions is to be calculated with formula (7).\nFormula (7) ΔΡ m − TA = P TA ∕ η Α − P TA ∕ η Α − EI\nWhere:\nΔΡm–TA Saved mechanical power under type approval conditions (W);\nPTA Electric power under type approval conditions, which is 350 W;\nηΑ Efficiency of the baseline alternator;\nηΑ–EI Efficiency of the high efficient alternator\nThe accountable share of saved mechanical power is calculated with formula (8).\nFormula (8) ΔΡ m = ΔΡ m − RW − ΔΡ m − TA\nWhere:\nΔΡm Accountable share of saved mechanical power (W);\nΔΡm–RW Saved mechanical power under real world conditions (W);\nΔΡm–TA Saved mechanical power under type approval conditions (W);",
