Daily management of power system in data center

Local time 19th, Nov, we luckily attended the Provincial Low-Voltage Electrical Industry Association Summit. During the meeting, we discussed “How to manage the power system in data center”. Let’s review the important points as follows:

1. Heat damages the battery. Avoid placing the battery too close to heat sources. The battery's permissible operating temperature range is -15~50℃, and the recommended cyclic operating temperature is 5~35℃.

2. Because the battery may produce flammable gases, do not install it near equipment that may generate sparks.

3. The room containing the battery must be well-ventilated.

4. When connecting batteries, there must be sufficient space between them. The minimum distance between two batteries is recommended to be 5mm~10mm.

5. If two or more battery packs are connected in parallel, they must be connected to the load using wires of equal length.

6. To obtain the longest battery life, the charging current should preferably not exceed 0.1C(A). The recommended charging voltage is 2.25V~2.30V/cell in float charging mode; and 2.35V~2.50V/cell in cyclic use.

7. When cleaning the battery exterior, only wipe the casing with a damp cloth dampened with clean water. Never use oils or organic solvents such as gasoline or thinner to clean the casing.

8. Touching the battery's conductive parts may cause electric shock; therefore, wear rubber gloves when inspecting or repairing the battery.

9. Do not disassemble the battery. If acid splashes onto skin or clothing due to mechanical damage, rinse thoroughly with plenty of tap water and seek immediate medical attention.

10. Batteries of different capacities, usage times, and manufacturers should not be mixed.
