Hi I am trying to find any regs, standards, codes or requirments for the ventilation of electric vehicle, lithium-ion charging stations.
It appears the Australian regulators may be lagging on this.
regs for Lithium- ion charging station

Have installed a couple of charging points for Teslas in peoples houses. The requirements are simple enough ventilation of Lithium, not of concern (EV car standards cover this) in the average garage, etc.

MemberThanks David,
Our problem is we are looking at a 270 car garage in a basement with around 30 percent allowance for electrical vehicles.The space will be mechanically ventilated as per normal combustion engine allowances but we are trying to work out is other factors need to be taken into consideration
Does AS IEC 61851.23:2014 : Electric vehicle conductive charging system - D.C. electric vehicle charging station which "adopts IEC 61851-23, Ed. 1.0 (2014), which together with IEC 61851-1, Ed. 2.0 (2010), gives the requirements for d.c. electric vehicle (EV) charging stations, herein also referred to as “DC charger”, for conductive connection to the vehicle, with an a.c. or d.c. input voltage up to 1 000 V a.c. and up to 1 500 V d.c. according to IEC 60038." adequately cover ventilating the space where around 90 vehicles may be on charge?Posted Tuesday 21 Jun 2016 @ 12:51:57 am from IP # -

MemberThe IC engine requirements should more than cover any EV requirements, particularly since you will at this point in time have to assume that all vehicles might be IC. The demand for ventilation for IC vehicles should be far higher than for EV's.
If you were to use the calculations listed in AS4086 for Lead Acid battery systems that would be more than adequate for LiFePO4, the other point about using that is that it covers any vehicles that might be Lead Acid also. Which I suspect would need to catered for even though they might either few or far between.
All Lead Acid Cells/batteries off gas to some extent even sealed ones.
Other issues for any battery ventilation requirements the ceiling must designed in such a way that there is NO place for pockets of Hydrogen gas to be able to accumulate so the ceiling must always have a way of allowing any gas to escape/exit no matter what and ideally, regardless of whether primary mechanical ventilation system is operating or not. It must not be able to accumulate in a confined area as you only need a low % of Hydrogen concentration to become an explosive environment. CO2 and the like tend to be heavier than "STD air" therefore tend drop down towards the floor.
