6 FAQs about [Cameroon bbu battery backup unit]

What is a battery backup unit (BBU)?

Battery backup units (BBU) supply power to computers and peripherals for a limited time during mains power outages or brownouts. DC/DC battery backup units are critical for avoiding catastrophic data loss in data centers and allow safe shutdowns of factory automation processes during outages.

How many kW can a BBU module provide?

These are the following: Battery pack capacity: The BBU module can provide 3 kW backup power not more than 4 mins over a period of 4 years. Battery cell type: The BBU module should have a Li-Ion 18650 type with 3.5 V to 4.2 V cell voltage, a minimum of 1.5 AH battery capacity, and a 30 A continuous rated discharge current.

What is a BBU module?

Battery pack configuration: The BBU module would have a battery pack configuration of 11S6P (six cells parallel strings of 11 cells in series each string). Also, the BBU module is required to have a BMS for battery charge/discharge algorithms, protections, control signals, and interfaces for communication.

How long does a BBU module take to charge?

The BBU module is expected to take over the busbar voltage within 2 ms with a backup time of 4 mins. Charge mode: This is when the BBU module enables its internal charger circuit to charge up its battery pack when all conditions are met.

Which microcontroller is used in a BBU module?

Each BBU module employs a main microcontroller and a battery management system (BMS) microcontroller. For Analog Devices’ reference design, the MAX32690, an ultra low power Arm ® microcontroller, acts as the main microcontroller and is responsible for six important processes (see Figure 1).

How many kilowatts should a battery backup unit supply?

DC/DC battery backup units are critical for avoiding catastrophic data loss in data centers and allow safe shutdowns of factory automation processes during outages. BBU should generally supply between one and four kilowatts. Read more
