Lead acid batteries cause unnecessary operational and capital expenditures Operational indicator Lead acid battery Implications for a warehouse operator Maintenance Charge duration, hours Required 8-12 In-house or outsourced maintenance personnel 2 or more batteries per truck Memory effect Yes Lower fleet availability due to work interruptions for charging Service life, cycles < 1 500 Periodic battery replacement Dangerous substances Battery generates explosive hydrogen during charging, sulfuric acid spills Build-up of an expensive battery room 2
EnSol has developed a lithium battery that solved the legacy problems Operational indicator Lithium battery Implications for a warehouse operator Maintenance Not required No maintenance cost Charge duration, hours < 2 1 battery per truck Memory effect No 100% fleet availability due to opportunity charging Service life, cycles > 3 000 No need to buy replacement batteries Dangerous substances No No need to build up battery room 3
EnSol battery lowers total cost of ownership of battery fleet in half Battery fleet costs Cost savings when switching to lithium batteries over 4 years at a warehouse with 30 forklifts, $k Share of the battery total cost of ownership, % Operational Maintenance 272 23% Electricity 54 5% Capital Lead acid battery excess capacity Battery replacement due to short life Included in the price of lithium batteries Buying additional trucks due to lower fleet availability 54 5% Build-up and equiping a battery room 163 15% Total 543 50% 4
EnSol lithium battery is completely maintenance-free Lead acid battery requires continuous maintenance Lithium battery is completely maintenance free Adding distilled water Cleaning and repair Warranty Swapping batteries 5
EnSol battery lowers electricity consumption by a quarter Energy draw from the grid Charger Battery room exhaust Battery Energy available to the ventilation truck EnSol lithium battery electricity throughput efficiency 100% 85% Losses 15% -25% Lead-acid battery electricity throughput efficiency 100% 60% Losses 40% 6
EnSol lithium battery requires much less capacity to do the same work Battery capacity LAB capacity that is unavailable because of: Voltage drop at high current Capacity reduction in Ah at high current Battery aging Impossible to discharge to 0% 100% 38% LAB excess capacity that can be reduced when switching to LB: LAB maximum current is limited by 1/3 of its capacity (LB maximum current is 9 times higher*) Trucks are equipped with large LABs to enable lifting Fast charge and opportunity charge make much smaller LB suffice Motor-hours per shift LB recommended capacity, % of LAB capacity >6 50% 4-6 40% <4 35% 62% 12-27% 35-50% Battery example, Ah Lead acid battery (LAB) nominal capacity LAB capacity unavailable in a warehouse truck application LAB equivalent capacity of EnSol lithium battery (LB) Excess capacity Lithium battery optimal capacity 775 480 270-400 * With the same LAB and LB nominal capacity 7
EnSol lithium battery increases warehouse truck fleet availability Battery state of charge, % 100% Truck with EnSol battery is always available for work due to fast charge and opportunity charge 80% 60% 40% 20% 0% 2 4 6 8 12 14 16 18 20 22 24 Lead acid batteries always run out during work and the truck becomes unavailable for the time required to swap the batteries* Time * The time required to change the battery is up to 5% of the total truck time 8
