3. SAFETY (CONTINUED)
The battery features design-specific mechanical, electrical, and electronic / software-
based provisions to minimize any expected risks. These measures include:
• A functional safety qualified electronic monitoring and control system to ensure safe
electrical operation (voltage, current and temperature limits).
• A safe shut off strategy to respond if limits have been violated (voltage, current, and
temperature).
• Contactor and fusing strategy to minimize the impact of external short circuits on the
battery, however arcing cannot be prevented in the most extreme cases.
• Dedicated handling / lifting points.
• Dedicated venting solution to respond to potential cell failure in order to mitigate the
impacts of the resulting outgassing.
To ensure safety follow the safety guidelines below:
• Operation must only be done in accordance to the limitations within this document.
• Stop the usage of the battery if there is a crush, pinch, cut or other damage to the
power cables or power connectors.
• Keep the battery away from heat sources.
• Keep the battery away from ignition sources.
• Do not operate the battery in a hazardous location like flammable or explosive
environment.
• Store only in monitored areas with suitable fire control and protection per local
requirements, e.g. local fire regulation and building insurance requirements
• Operate only in monitored areas with suitable fire control and protection per local
requirements, e.g. local fire regulation, building insurance requirements
• Operation must only utilize EnerSys
®
qualified hardware and software as delivered
and installed by EnerSys personnel (no customizations are allowed).
• Charging must only be performed with EnerSys approved chargers for NexSys ® iON
batteries.
• Handling and storage must be in a dry environment.
• Prevent immersion of the battery into water.
• Handling and service of the battery requires proper training of EnerSys approved
technicians with appropriate rated tools and personal protective equipment.
• In the case in which the battery has been operated or stored outside of the allowable
limits as stated by this document, cease operation and contact EnerSys.
• In the case of any error that cannot be reset – do not continue operation of the
battery until support and direction is provided by EnerSys.
The EnerSys NexSys iON battery is a sealed product, however in case of cell damage
within the battery there is still the chance of electrolyte leakage, as well as other
hazards. Please follow the directions below if any of the following incidents take place.
Additional information can be found in the Lithium-ion Battery (Module) SDS:829515.
• If leaked electrolyte comes into contact with a person’s skin or eyes, rinse the
affected areas with clean water for at least 15 minutes. Then in all cases, immediate
medical attention must be obtained.
• If leaked electrolyte comes into contact with the mouth, or is swallowed, rinse out
the mouth as well as the area around the mouth, then immediate medical attention
must be obtained.
• If thermal burns are caused, treat them accordingly; then immediate medical
attention must be obtained.
4. USAGE
The NexSys iON battery must be used, operated and serviced in accordance with
these operating instructions. The operating instructions of the truck and battery
charger are required to be respected in addition to these operating instructions. In
case the permissible operation parameters of the industrial truck are stricter, the
truck limits must be respected for usage. For example, the permissible range of the
battery application temperature does not increase the permissible range of the truck’s
application temperature.
When the battery is installed into the truck, the traction connector of the battery is to
remain connected to the truck at all times. Never charge via the traction connector. For
charging, the charging plug(s) single or dual must be connected to the EnerSys approved
charger. Upon plugging in the first charge cable, the traction path is opened so that
the industrial truck cannot be operated inadvertently. For charging instructions refer to
Chapter 16.
4. USAGE (CONTINUED)
In the event of discharging below the usable energy resulting in the battery shutting
down due to low State of Charge (SOC), there is a feature to allow the truck to be
operated on a very limited capacity and performance in order to immediately return
to a matching charger. When a low SOC related tripping of the battery occurs, a
restart (same as turning the pack on) is allowed to reset the pack once. If the battery
is not placed on charge as soon as possible and allowed to discharge this limited
capacity, the battery will once again shut down.
This time it will be locked out and
require a service visit.
This limited capacity is intended to only allow for the truck to be
driven a limited distance and not be used for any lifts.
Opportunity charging is highly recommended in order to maximize the daily run
time capability of the battery. It will also optimize the service life of the battery by
decreasing the discharge window of the battery during discharge.
For the NexSys
®
iON battery, it is acceptable and is actually beneficial for lifetime to
operate a partial state of charge.
The battery temperature has an effect on the capacity of the battery. For example, run
time may be reduced at lower temperatures.
Battery temperatures at the extreme ends of the temperature limits as stated in
this manual will have an effect on performance, possibly resulting in an unexpected
shutdown.
All visual and audible warnings are to be respected and reviewed.
The battery will go into a hibernation mode after a default of 8h when there is less than
a default of 3A current draw. It can be reactivated by restarting the battery by the various
start methods.
5. ENVIRONMENTAL OPERATION LIMITS
The battery is rated to IP54 therefore do not clean the battery with pressurized water.
Do not use the battery outdoors without suitable weatherproof protection.
The battery must not be operated or stored in conditions where it can get immersed.
The battery storage temperatures are -40°F (-40°C) to 140°F (60°C).
The battery operating temperatures are 14°F (-10°C) to 131°F (55°C).
Keep away from fire, sparks, and heat.
Battery must not be exposed to extended periods of direct sunlight that allow the
temperature of the battery to rise above the storage and operating temperatures of the
battery.
Batteries must not be operated in condensing environments.
6. FIRE EXTINGUISHING
In the unlikely event of a thermal runaway, which may result in a visible release of gas
and/or intensive smoke build-up from the battery,
evacuate the location immediately
and contact Emergency Response . If there is an irritation of the respiratory tract, seek
immediate medical attention.
Firefighting operations must be performed based on guidance provided in the Lithium-
ion Battery (Module) SDS:829515 by trained firefighters with full
personal protective
equipment
and self-contained breathing apparatus. Ensure that emergency responders
are informed that the battery has Lithium-ion chemistry. Any indication of a thermal
event (gas, heat) requires fire suppression methods to be applied (absence of flame is
not sufficient to consider the thermal runaway event stopped or extinguished).
Large amounts of spray water and/or complete immersion into water can be used
effectively to cool the battery and contain a Lithium-ion battery thermal event.
In the case of the battery outgassing or after suppression of the fire, store the battery in
a safe place outside (access restriction, hazard indications) for a minimum of 24 hours. It
is recommended to monitor the temperature frequently to detect any potential new heat
generation. In the instance that a thermal event reoccurs follow the same firefighting
methods.
7. SAFETY VENTING
In the case of a thermal event, the battery is specially designed with a venting aperture
to ensure any hot gases are vented AWAY FROM THE OPERATOR in a safe manner.
