Lithium batteries offer all types of facility operators a new set of solutions to help improve their energy storage performance.

Lithium batteries are the ideal solution for all applications requiring a high number of cycles, high rate performance, new concepts of facility operating modes such as “peak shaving” or where there are very limited space and temperature constraints.

Thanks to the chemical and technological advances made during the last 10 years, Riello UPS and Riello Solartech introduce lithium battery solutions that are a valid alternative to the conventional lead acid battery for a wide range of usages. The innovative lithium technology proposed by Riello UPS provides several advantages over traditional lead acid battery solutions, starting with the smaller number (or even the absence) of replacements for the entire duration of the UPS and ESS installation life cycle, which reduces or eliminates the risk of interruptions due to replacement of the batteries and granting an important cost saving. Lead acid batteries require a managed room temperature around 20/25 °C, which has a high impact on cooling system design. The lithium battery has a greater tolerance to high temperatures (including casual spikes) and if the UPSs / ESSs and servers are also designed to tolerate higher operating temperature, it is possible to save money, downsizing the cooling system and reducing the electricity costs. Furthermore, for the same amount of energy supplied their weight is reduced by more than half, which makes them more manageable and easier to position. The footprint is reduced by up to 75% of Energy Storage UPS AND ENERGY STORAGE SYSTEMS (ESS) POWERED BY LITHIUM BATTERY SOLUTIONS conventional lead acid batteries, leaving free space for additional IT equipment or additional room to accommodate future power upgrades. Unlike lead acid batteries, the capacity does not degrade as a function of the discharging current rate: in case a high discharging current is required, the cell capacity is maintained, no oversizing is required, and a high cost saving is achieved. The number of charging / discharging cycles is increased over 10 times, depending on the technology, temperature and depth of discharge. This is a fundamental feature to enable UPS/ESS applications requiring a high number of battery cycles as “peak shaving” and “OFF GRID configuration”. The charging times, which are essential in the various blackout scenarios, are at least four times faster and this must be taken into account in a smart grid and smart energy perspective; for instance in all hybrid installations (grid/GE + solar + wind) that requires higher charging / discharging rate. Because such technology requires electrical cell balancing, the Riello UPS lithium battery solution integrates a sophisticated Battery Monitoring System, (typically not part of a lead acid battery solution for UPS systems), that guarantees improvements in the performance, safety, and reliability of the as well as enabling full system supervision. Riello UPS lithium solutions are compatible with much of the Riello UPS product series and the Riello Solartech energy storage portfolio and easily adaptable to any customer needs in terms of power, architecture and installation requirements.

EXTENSIVE RANGE OF SOLUTIONS

The Riello UPS lithium battery proposal incorporates several solutions spanning a large number of application requirements that meet the most pressing market demands. This is achieved through a series of products that are characterized by discharging duration time, number of battery cycles and charging / discharging current rate.
