Maxwell Technologies expanded its ultracapacitor-based Engine Start Module (ESM) product line, unveiling its Class 3-6 entry at the Work Truck Show in Indianapolis. to provide the same benefits to Class 3 through 6 medium-duty trucks that it has been offering previously to Class 7 and 8 heavy-duty trucks.
Dennis Flynn, Maxwell Director Market Research and Brand/Communications, says the unit produces 900 cold cranking amperes (CCA), or a three-second crank and eliable starting for diesel engines up to 9.9 liters at temperatures -40°F to 149°F.
A built-in quick charging system can resupply the unit in 15 minutes or less and by using the ESM, Flynn says fleets can extend battery life, since the unit handles all the load for cranking.
Maxwell’s ESM ULTRA 31/900 is wired directly to the starter and assumes the starting responsibility for the truck, effectively eliminating cranking problems that come from weak or discharged batteries. Flynn says the ESM ULTRA 31/900 delivers a quick-burst of power trucks need to crank their engines. The new ESM tips the scales at 16 lbs. and leaves the reamining batteries to operate auxiliary features like lift-gates and buckets without draining cranking power.
The ESM ULTRA 31/900 is a no-acid, lead-free energy storage solution that weighs less than one-fourth 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, the company says.
