6 Frequently Asked Questions about “Battery room temperature requirements”

Do battery rooms need ventilation and temperature maintenance?

Battery Rooms require ventilation and a maintained temperature range. How can the ventilation rate and temperature maintenance be designed to the optimum? The paper proposes the minimum performance requirements for the temperature range and ventilation of rooms containing the batteries supporting Uninterruptible Power Supply (UPS) systems.

What temperature should a battery be kept in?

The battery room temperature should be between + 5° C and + 25° C. Inside the battery the maximum temperature difference between cells and blocks must not exceed 10 K for vented and 5 K for valve regulated batteries. The surface resistance of the protection clothing must be < 108 W to avoid static charging.

What are the minimum requirements for the design of a battery room?

The following performance criteria (in Italics) are the minimum requirements proposed for the design of a battery room. The widest possible temperature range for the battery room shall be designed to optimise the performance of the batteries. The mechanical systems shall have N+1 redundancy.

What temperature should a standby battery be kept at?

High temperatures increase the capacity of the cells, but decrease the life, while low temperatures reduce the capacity temporarily but have no long term adverse effect. The standard capacity rating for a standby battery, is at a temperature of 25c and it is therefore advisable that the battery room be kept as near to this temperature as possible.

How should a battery room be designed?

Battery rooms shall be designed with an adequate exhaust system which provides for continuous ventilation of the battery room to prohibit the build-up of potentially explosive hydrogen gas. During normal operations, off gassing of the batteries is relatively small.

What are the requirements for a stationary battery ventilation system?

Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.
