I work with a number of high-profile golf clubs
I am increasingly seeing golf clubs provide trolley sheds with battery charging facilities for member’s electric trolleys (not ride on disabled trolleys but golf bag, battery-powered, self-propelled trolleys)
Seeing 100 batteries on charge at the same time is not uncommon, I have one client where that number is generally over 400
Seeing Pro shops with 10 on charge is also not uncommon, stuck around the back of the shop, in areas of multiple sources of combustion and away from the public eye.
There are a number of proprietary types but the most popular by far is http://www.powakaddy.co.uk/
They have a number of battery sizes, both lead acid and lithium ion type, member’s trolleys can vary hugely in age and charger type.
My concern is the charging process, the integrity of the chargers and fire prevention.
Most golf clubs employ a handyman, I advise clubs purchase a portable appliance tester, provide training and ensure competence on the use of it, and test all battery chargers on a 6 monthly basis as they are high use.
Chargers are generally on all the time, and if a member goes on holiday for a month, he will just leave his battery on charge for the duration
Chargers should turn themselves off when battery reaches full strength but it does not stop them getting hot
Chargers that come with the batteries are supplied by the battery manufacturers, although the clubs have no way of preventing members from buying replacement batteries and chargers from e-bay
For your entertainment
I yesterday encountered
A shed that has 150 chargers
Outside is a tank holding 2000 litres of kerosene and a 12 x 8 wooden shed full of teak benches
Oh and this trolley shed has no fire suppression or fire detection system, it does though have a single always locked door with a very pretty fire exit sign over the top
Concerning only the charging process and potential fire risk, can anyone offer any insight into the fire potential that charging so many batteries in a single location presents.

Here are some suggestions;

• First up a Fire Risk Assessment should be carried out.
• The batteries should have a dedicated room for this task given the amount of batteries on charge.
• The room should have automatic fire detection in it.
• Fire fighting equipment should be located in the area (i.e. Co2 extinguisher).
• There should not be any combustible material within the room.
• The room should be well ventilated (to remove any potential build up of hydrogen gas – led acid type batteries).
• There should be an eye was station located nearby.
• The electrical charging equipment must be safe (possibly PA Testing).
• A dedicated charging power ring main could be on a timer, for example only powered up during the day, and say at 5pm the power is killed until the next morning. And protected by RCD to prevent any overload of the circuit, and to protect the golf members using the equipment.
• The room must be regularly checked, for example on a daily basis.
• You may also want to consider charging the members for this service; this will do two things, help fund all of the above suggestions and may force others to charge their batteries at home reducing the risk.

Hope this helps.

Just a quick thought.
Put dedicated single socket outlets in, ban extension leads and socket "multipliers".
Put each socket outlet on an 30mA RCBO, that way more than 30mA of leakage and the charger is killed.
If a users charger trips the RCBO, their fault.
Get another one that doesn't trip or charge it somewhere else.
Plus I like a lot of the suggestions Toe has made.
