Ultracapacitor for Medium-Duty Trucks
Maxwell Technologies is expanding its ultracapacitor-based Engine Start Module (ESM) product line to provide the same benefits to class 3 through 6 medium-duty trucks that it’s been offering previously to class 7 and 8 heavy-duty diesel rigs.
Like the current ESM product, the new ESM Ultra 31/900 provides 900 cold cranking amperes (CCA), or a three-second crank; reliable starting for diesel engines up to 9.9 liters at temperatures -40°C to 65°C (-40°F to 149°F); low-maintenance operation and life-of-the-vehicle reliability; industry-standard Group 31 battery form factor for easy integration with battery systems; built-in quick charging system (15 minutes or less); extended battery life; full compatibility with existing battery systems; and a four year unlimited warranty.
Maxwell’s ESM ULTRA 31/900 assumes the starting responsibility for the truck and effectively eliminates cranking problems that come from weak or discharged batteries, the company says. The new ESM is light at just 16 lb. Not only does it deliver reliable normal starts, it also allows extensive use of lift-gates and buckets while the engine is off without fear of the truck not firing up.
The ESM ULTRA 31/900 is a no-acid, lead-free energy storage solution that weighs less than 25% of the Group 31 lead-acid battery it replaces. It stays fully charged even when the truck’s lead-acid battery is as low as 9.5V.
