Battery Charger – Electric Vehicles
BATTERY CHARGER – ELECTRIC VEHICLES
DANGER
• The charging area must be ventilated. Hydrogen level in the air must never exceed 2%. The total
volume of air in the charging area must be changed five times per hour. Exhaust fans should be
located at the highest point of the roof. Contact a local HVAC engineer.
• Do not charge the vehicle batteries with the vehicle covered or enclosed. Any enclosure or cover
should be removed or unzipped and pulled back when batteries are being charged. An accumulation
of hydrogen gas could result in an explosion.
WARNING
• Only trained technicians should repair or service the charger. Contact your nearest Husqvarna
distributor/dealer.
• Each charger should have its own dedicated 15 or 20 ampere separately protected (circuit breaker or
fuse) single phase branch circuit, in accordance with all applicable electrical codes for the location.
• Connect the charger AC supply cord to a properly grounded, three-wire outlet of the proper voltage
and frequency as shown on the charger.
• Do not use an adapter to plug the charger with a three-prong plug into a two-prong outlet. Improper
connection of the equipment-grounding conductor can result in a fire or an electrical shock.
• An extension cord or electrical outlet must accept a three-prong plug. Extension cord should be a
three-wire No. 12 AWG (American Wire Gauge) or No. 14 SWG (British Standard Wire Gauge), and be
as short as possible. The use of improper extension cord could result in fire or an electrical shock.
• Do not operate the charger if it has received a sharp blow, was dropped, or otherwise damaged
in any way.
• Have worn, cut, or damaged power cords or wires replaced immediately.
• Do not use near fuels, grain dust, solvents, thinners, or other flammables. Chargers can ignite
flammable materials and vapors.
• Do not expose to rain or any liquid. Keep the charger dry.
• Never push objects of any kind into the charger through cabinet slots. They may touch dangerous
voltage points or cause an electrical short circuit that could result in fire or electrical shock.
• Do not connect a stationary charger to the receptacle if the charger cord, plug, or the vehicle
receptacle is broken, damaged, or does not make a good electrical connection. Fire or personal injury
can result. Have a qualified technician replace the parts.
• When the charger is on, the charger DC cord may be disconnected from the vehicle receptacle slowly.
Jerking or pulling the DC cord out quickly could cause arcing and burning that could damage the plug
and receptacle and could cause batteries to explode.
• Do not block or cover the charger ventilation slots. The slots provide ventilation and protect the
charger from overheating.
• Do not allow clothing, blankets, or other material to cover the charger.
• Do not allow the charger to operate for more than 30 minutes at 19 or more amperes.
• Install surge arrestors on incoming AC power lines. Surge arrestors will help protect electrical
components in the charger and on the vehicle from all but direct or close lightning strikes.
NOTE: Because the vehicle’s onboard computer (OBC) has a storage charge feature that automatically checks and
recharges the batteries as necessary every 15 days, the charger can remain plugged to an electric vehicle
throughout the storage period.
At one hour and at two hours into the charge cycle, the charger will shut off in order to run a self-diagnostic
program (ammeter will drop to zero). Charging will resume in a few moments (ammeter returns to previous
rate of charge).
