Lithium-Ion Battery System Beats TCO of Lead-Acid Back-Up Power Units by 40%

San Jose, CA (PRWEB) July 25, 2016

Lithium Power announces a more cost-effective, space-saving solution for emergency back-up power installations, based on lithium-ion batteries fully integrated into a Battery Management System (BMS). The BMS monitors battery health and status, communicating with technicians and engineers over the internet. This internet-of-things approach significantly upgrades the ability of utilities, hospitals, production facilities, server farms and other operations to obtain a cost-effective but highly reliable back-up power source, ready to go when their main electricity source fails.

Many of these enterprises currently rely on lead-acid battery systems to provide emergency back-up power. The technology is stable, well-known and reliable. But, these installations have relatively short five-year lifespans, have to be visually inspected constantly, and take up a lot of space.

Lithium-ion batteries take up much less space and last longer, but have earned a reputation for overheating, as evidenced by recent hoverboard product problems. This is the biggest issue that needed to be resolved before lithium-ion batteries could replace lead-acid batteries as the best emergency power option.

A properly designed BMS combined with the battery set solves the problem. It leverages the benefits of internet connectivity to allow technicians and engineers to monitor battery sets and their environment (including temperature) remotely. The system also automatically takes action to keep temperature under control, reducing risk and wear-and-tear. The BMS also extends the life of a lithium-ion battery emergency back-up system to ten years, double the lifespan of lead-acid systems.

Lithium Power has created a lithium battery energy storage system, the ESS-500-48, which incorporates a new BMS. This proprietary BMS uses an internet-based reporting system that allows engineers to remotely monitor the back-up power system after installation, even using their smartphones.

"Lead-acid battery power levels need to be visually checked daily. Lithium battery systems do not," reports Wilson Chan, CEO of Lithium Power. "This saves a lot of man-hours, as our BMS proactively alerts engineers if any issues arise, such as temperature changes in the installation room that could affect battery performance."

"Back-up power must be 'always on,' ready to go online at a moment's notice to keep the facility it supports fully operational," says Chan. "But the other perhaps unexpected advantages of switching to lithium batteries from lead-acid batteries are simplified management and saving space."

A lithium-ion system beats lead-acid alternatives on TCO because lead-acid battery installations are large, heavy units that need a lot of durable floor space to comply with construction and maintenance regulations. Lithium battery units are far lighter and take up over 80% less space. Said another way, a lithium battery-based system delivers the same back-up power using 20% or less of the floor space of a lead-acid battery installation.

"If you make a conservative assumption that floor space costs $1 per square foot monthly, paying for the floor space of a lead-acid battery solution would be 50% of the total cost of ownership (TCO) of a typical installation. With lithium batteries, the lease costs for the floor space needed drops to about 8% of TCO," notes Chan. "That savings drops straight to the organization's bottom line even if it owns the building, because they don't have to reserve nearly as much floor space for the necessary back-up power equipment."

Lithium Power found that in a recent installation in a large university hospital [http://www.lithiumpowerinc.com/pdf/ess-500-case-study.pdf , the average cost per watt/hour of available power (TCO) for the Lithium Power ESS-500-48 has been $1.74, where the TCO for a comparable lead-acid battery pack installation would have been $2.90. This is a reduction of 40% in TCO, while still increasing reliability and ease of management.

In higher-rent buildings, where space is at much more of a premium, the impact of the rental or lease savings on back-up battery power TCO becomes even more significant.

"Whether you have a hospital caring for patients, or a server farm supporting cloud computing, back-up power that really is reliable is priceless," says Chan. "Why not choose the latest in technology to ensure that you have it when you need it?"
