Maxwell Technologies 24V Ultracapacitor-Based Engine Start Module (ESM)

Maxwell Technologies, Inc. announces its 24V ultracapacitor-based engine start module (ESM), ideal for improving equipment uptime and power reliability in buses and industrial vehicles.

• Enables vehicles to start and operate reliably in the face of cold weather and infrequent starting
• Takes over the engine cranking and starting function by remaining fully charged, even if battery voltage drops significantly
• Avoids common problems experienced when using lead-acid batteries to start diesel engines
• Allows machines to provide stable power to sensitive electronics by removing batteries from the cranking equation, preventing problems that coincide with trying to start a machine with dead batteries
• Two models of the 24-volt ESM: The ULTRA 31/900/24V for starting diesel engines up to 12.5 liters and the ULTRA 31/1100/24V for engines up to 15.0 liters
• Both models are packaged in BCI Group 31 form factor
• Charges and discharges in as little as fractions of a second
• Performs normally over a broad temperature range of -40 to 65 C (40 to 149 F)
• Operates reliably in up to 1 million or more charge/discharge cycles and resist shock and vibration
• Cells range in capacitance from 1 to 3,400 farads
• Multi-cell modules range from 12 to 160V
