Scotty Ai controls the Bidirectional Motor Generator to operate as a Mild Hybrid with Electric Launch Assist. § Scotty AI V3 drives the mild hybrid functionality of the BMG: § Every time your Sprinter starts moving from 0 km/h, the engine must overcome vehicle inertia — and it does this inefficiently at low RPM (typically <1200 RPM). § Once the throttle is applied after idle and the engine RPM starts to rise, Scotty AI switches the mode of operation from “power generation” to “mild hybrid” motor power assist to engine. § Your Scotty Ai and BMG now delivers 10 kW of torque assist during this inefficient phase. § This means less diesel energy is needed for initial acceleration. § Once the Mercedes Sprinter engine RPM passes a configurable setpoint of RPM, Scotty AI switches the BMG to power generation mode and winds it up progressively to 8kW and up to 3kW from the DC DC independent function. A conservative estimate is 10kw of power at cruising speed. How much energy comes from the 48V battery and what is the impact on battery life? § 10 kW × 4 seconds × 30 launches/hr = ~334 Wh/hr of electric launch energy § For urban delivery van with 10 hours/ day that’s 3,340Wh of battery energy per day § 4 x Safiery Solid State Lithium batteries are 11,120Wh capacity § However, when the Sprinter is driving over 1200RPM the replenishment energy is the same so if the vehicle is over 120 secs an hour, the replenishment energy matches the mild hybrid power. § Safiery Solid State Lithium batteries have a 10,000 cycle life. A cycle is contiguous use of energy to 1C. 1 cycle every 3 days. It would be 3,330 days to 80% battery capacity – about 9 years. What are the fuel savings and $ per year estimated savings? § Daily distance § 200 km § Drive type § Urban (stop-start, low avg speed) § Baseline fuel consumption § ~14–16 L/100 km § Total daily fuel use (baseline) § 28–32 L/day § Fuel price § $2.00/L (AUD est.) § Hybrid assist § 10 kW from 0–1200 RPM per stop § Fuel savings from assist § 8–12% typical in urban use Fuel Usage (Baseline Savings (%) Fuel Saved (L) 28 L/day 8–12% 2.24–3.36 L 32 L/day 8–12% 2.56–3.84 L
At $2.00/L, your daily savings would be: § Low estimate: 2.2 L × $2.00 = $4.40/day § High estimate: 3.8 L × $2.00 = $7.60/day Annual Fuel Savings (Assuming 250 working days): Fuel Saved per Day Annual Savings 2.2 L $1,100/year 3.8 L $1,900/year
