Energy Storage System (ESS) Battery Considerations

Presented by: Paul Rogers, FDNY Lt. HazMat Unit 02/02/2016

UPS vs ESS Systems

UPS ESS

Back-Up

Peak Shaving/ Demand Reduction

Lead Acid ONLY

Numerous Chemistries

Full SOC Exercised Daily

No BMS BMS

Code & Standard Regulations

• FCAC (IFC)

• UL (9540)

• NEC

• NFPA

• DOE

• Con Ed

• FDNY C of F29

Location

• Where??? • Who is affected?? • Fire Appliances • Suppression Systems • Inside or Outside

Rooms vs. Cabinets • Rooms / Isolated • Cabinets / part of a room • Ventilation • No Ventilation

BMS Awareness

• Battery Brains • Safety Device • Monitors Cell/ Module /

Battery / System • Monitors Remotely • Collects Data

New BIC Card Entry

Capt. Carey will address

Signage

• Its for everyone

• Stranded Electric

• Corrosive

• Stay Out

Emergency Response Plan

• Need to be updated

• EAP Evacuations:

• In-Building Relocation Floor(s)?

• Total Building?

• What's your thoughts?

Potential Monitoring

• May Be required

• Why do they alarm?

• What’s the concern?

• What can be done?

Stranded Energy

• After fires

• Shutting down systems

• Loss of electricity

• Automatic shutdown

• Showing no stored energy

• Arc flash

Lithium-Ion Hover Boards

• Problems/Fire

• Agencies are investigating

• Industry/Public Concerns

• Insults to the battery

• Substandard Charging Device

• Non-Listed Batteries

ESS Re-ignition Concerns

• Extinguishment • Containment • Suppression • Fire watch???? • Removal???? • EV Test

Fires & Toxic Gases

Depends on chemistry • What is released during fire? • How much is released? • Fire intensity

Spills

• Aqueous Electrolyte

• Non Aqueous Electrolyte

• Corrosive

• Harmful to skin

• First Aid

• MSDS/SDS
