eCALL and Door Lock
Emergency call (eCall) and door lock/unlock are auto applications that require reliable backup power in the event the vehicle’s main power system fails. In traffic collisions, it is likely that the vehicle’s battery system becomes damaged or unavailable, making the backup power source of paramount importance to ensure critical subfunctions remain operational.
Maxwell’s proprietary ultracapacitor technology specializes in high power backup for eCall, door lock/unlock and other subfunctions that require reliable power in the range of a few seconds to two minutes. Our solutions offer excellent performance in cold, hot and humid environments and feature a compact form factor for streamlined integration.
eCall – The Emergency Call Service
As of spring 2018, all new cars and light commercial vehicles in the European Union must feature eCall to help reduce emergency response time for vehicles involved in an accident. Our ultracapacitor solutions help to ensure reliable backup power for this soon-to-be ubiquitous application.
Door Lock/Unlock – Reliable Activation
Maxwell ultracapacitor solutions provide instantaneous high power for reliable door locking and unlocking and high resilience in varied weather conditions.
Product Recommendation: XP™ Series Ultracapacitor Cells for Compact, Reliable Power
Maxwell XP™ Series cells are tailored to automotive environments by delivering reliable, efficient performance within an extended temperature range while helping to enable sleeker packaging and flexibility when designing for a 12V system solution.
Our XP Series ultracapacitor solutions are specifically designed for optimum performance in hot and humid environments—conditions that often limit the lifespans of lead-acid batteries. The XP cells also excel down to
-40°C,* providing a wider operating temperature range than most battery technologies available.
