Our in-house R&D team spent years researching and testing prototypes to provide the best solution for charging batteries in a location that can be stored away from critical buildings, whilst still being accessible and easily mobile. 
The EN14470 Fire Rating standard was written for flammable liquids and not lithium-ion batteries, meaning any test procedures and conclusions are incomparable to lithium-ion battery charging products.
The standard also requires that the ventilation to the unit shut off at 70℃. However, when a lithium-ion battery goes into thermal runaway and releases dangerous gases, ventilation is required to avoid a large explosion
Both EN14470 and EN 1363-1, fire-rated units can contain a fire on the inside or prevent it from the outside but both designs lead to much hotter charging environments, encouraging thermal runaway.
The heat curve for the fire-rated test below takes 20 minutes to reach 800 degrees. However, a lithium-ion thermal runaway event will reach 800℃ in seconds, making it a very different comparison.
It’s also difficult to move indoor fire-rated cabinets, especially in the event of a fire, where there could be a build-up of gases inside.
Our PowerStor unit is a complex but vital addition to the market, created specifically for the suppression of lithium-ion battery fires in a compact and accessible way.
