Battery Back-up Unit
BBU—a new low-carbon alternative for uninterruptible power systems
In the past, the uninterruptible power systems (UPS) of data centers used lead-acid batteries. These days, however, they are beginning to use more efficient, more cost-effective and environmentally friendly battery back-up Unit (BBU) to ensure stable power supply.
Atemitech’s BBUs are safe and reliable. These 24V/48V battery packs have energy density (Wh/L) and power density (W/Kg) that exceed those of lead-acid batteries. The battery design, high-quality materials and precision manufacturing all meet the tough testing requirements of customers that demand reliability, competitive P/C ratio and environmentally friendly design.
Advantages of Atemitech BBUs
Compact form factor
Our backup batteries (BBU) use lithium batteries, which are about 70% smaller and 60% lighter than lead-acid batteries, which makes for easier installation in modern server racks.
Lithium-ion batteries have a relatively low failure rate in mission-critical environments and are therefore perfectly suited for application in backup systems for enterprise networks, data storage centers, cloud servers, 4G/5G telecommunication systems, and large-scale energy storage.
The lithium batteries in our BBUs have a five times longer life span than lead-acid batteries in conventional UPS systems. Our BBUs are also more environmentally friendly, better recyclable, and they charge faster. For instance, our data center rack-type BBUs recharge to 90% in about two hours, which is about twice as fast as UPS systems’ lead-acid batteries.
More environmentally friendly
Lithium-ion batteries are lead-free, which is more environmentally friendly compared to lead-acid batteries. Our lithium batteries recharge faster and use less power, which results in longer life cycles, later replacement and less energy for production and transportation.
Atemitech’s BBUs have a built-in battery management system (BMS), which carries out failure monitoring, battery balancing and power optimization for each individual battery.
