Hybrid energy storage
The hybrid battery system is based on an energy storage architecture combines two complementary technologies in an intelligent way: high energy density chemical batteries and high cycle-life systems such as supercapacitors or LTO cells. The core principle is the dynamic allocation of energy flows based on the usage profile.
High cycle-life devices are used to manage rapid energy variations, such as load peaks or temporary imbalances between generation and consumption, while chemical batteries are used for long-term energy storage and release.
This approach significantly reduces equivalent cycles on the main batteries, limiting wear and improving their lifetime. In photovoltaic systems, for example, supercapacitors can compensate daily fluctuations, while batteries are mainly used during nighttime.
In autonomous applications, such as solar-powered devices, high cycle-life systems can be used as the primary energy source during normal operation, reserving the use of batteries for critical environmental conditions.
The result is a more efficient and reliable energy storage system, designed to maximize the overall lifetime of the entire system.
Operating principle of the hybrid system
Energy storage technologies
The hybrid storage system is based on the integration of two complementary technologies: high energy density chemical batteries and high cycle-life devices such as supercapacitors or LTO cells. Batteries allow large amounts of energy to be stored at relatively low cost, while supercapacitors can handle a very high number of charge and discharge cycles with high efficiency.
This difference in characteristics enables a functional distribution of energy flows, where each technology is used in the conditions where it performs best. The result is a more efficient system in which energy capacity and cycling capability are optimally balanced.
System architecture
The system architecture includes two separate storage systems, managed by an electronic control unit capable of dynamically selecting the most appropriate energy source. High cycle-life devices are used to handle rapid or temporary charge and discharge events, such as fluctuations in production or load demand.
Chemical batteries are instead used for longer-term energy storage and release, reducing the number of cycles they undergo. This approach limits stress on the main batteries, improving both reliability and overall system lifetime.
Lifetime and cycling
The lifetime of an energy storage system is strongly influenced by depth of discharge and the number of charge and discharge cycles applied to the batteries. The adoption of a hybrid architecture significantly reduces equivalent cycles on chemical batteries by transferring frequent stress to high cycle-life devices.
This behavior allows batteries to operate under more favorable conditions, preventing accelerated degradation. The result is an increase in overall system lifetime, improved long-term stability and reduced maintenance or replacement needs.
Proprietary technology
The developed technology is based on a patented hybrid energy storage architecture designed to optimize energy management and reduce stress on chemical batteries.
The integration of high energy density systems with high cycle-life devices significantly improves overall system lifetime and reliability, adapting to different operating conditions.
This approach represents the core of the proposed solutions and a key differentiating element in advanced energy applications.
