Battery Bank Risks
Like all electrical systems operating at high voltage, a battery facility poses traditional hazards such as arc flashing, electrocution and electrical fires. These hazards are well-known, and the controls understood. However, the US-based National Fire Protection Association (NFPA) has highlighted four hazards specific to BESS (Ref. 5). 1.
What are the dangers of a battery?
The following is a list of battery is issues that can manifest in a dangerous way: Short-Circuiting: If the electrical current in a battery is released in an uncontrolled manner or the current passes through a conductor with too low of a resistance, a large amount of energy will be delivered in a short period of time.
How to reduce the safety risk associated with large battery systems?
To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
What happens if a battery is damaged?
Where the battery is damaged, it can overheat and catch fire without warning. Batteries should be checked regularly for any signs of damage and any damaged batteries should not be used. The incorrect disposal of batteries – for example, in household waste – can lead to batteries being punctured or crushed.
Are batteries safe?
However, despite the glow of opportunity, it is important that the safety risks posed by batteries are effectively managed. Battery power has been around for a long time. The risks inherent in the production, storage, use and disposal of batteries are not new.
What happens if a battery is not stored properly?
Therefore, any of this solution not properly stored in the battery can serve as a risk to anyone handling the battery or even in the near vicinity. Flammable Gasses: Some batteries emit hydrogen gas during charge and discharge cycles due to the reaction between water and sulfuric acid.
Are batteries a fire hazard in the UK?
Legal regime The UK already has legislation in place dealing with fire and safety risks such as those posed by batteries. For example, the Health and Safety at Work etc Act 1974 (‘the 1974 Act’) requires employers to ensure the safety of their workers and others in so far as is reasonably practicable.
