Green Cubes Lithium Safeflex Series User manual

QuickStart
Guide
Welcome to the world of
lithium-ion
Green Cubes SAFEFlex lithium-on batteries are safe, reliable, and
provide exceptional cycle life and cost of ownership. This guide will
help you understand the basics of storing, installing and operating
your new Green Cubes SAFEFlex lithium-ion battery. Please read
through this guide and contact us if you have any questions.
Safety and Precautions
• Battery should be handled and installed by a trained
professional with proper lifting straps and equipment rated
for weight listed on data plate.
• Prior to servicing, the battery must be keyed off and
disconnected from truck and/or charger.
• Battery is only to be opened by trained professional.
• Cell tops must be insulated before performing all service work.
• Tools must be insulated to protect battery against short
circuits during servicing.
Installation
The battery should be installed in the battery compartment by a
trained professional using a forklift and lifting straps. In addition,
there are cutouts in the battery case that must be used when
lifting the battery. The service weight of the battery is printed
on the data plate. Make sure your equipment is properly rated to
handle the battery weight.
Main Power Connection
Once installed, the main power connection should then be
connected to the truck and will be either a Euro or SB style
connector (shown below).
Truck- Battery Data Connection
In some cases, the battery and truck will have a separate data
connection that must be connected as well. The data connection
is required on some trucks to provide accurate battery discharge
indicator reporting and/or Early Warning System (EWS) information.
If a data connection is required, the battery will not supply power
to the truck until it is properly connected. If there is no data
connection, then a battery discharge indicator (BDI) is required.
On/Off Switch
The on/off switch should be easy to locate on
the outside of the battery. To turn the battery
on, press the switch. The line designates the
on position and the circle designates off.
If the battery is being stored or waiting for
deployment in a truck, make sure it is turned off until put into use.
The Battery Management System draws a small amount of power
and will slowly discharge the battery over time. Turning the battery
off prevents the possibility of overdischarge.
Battery Discharge Indicator
If there is no data connection to the truck, the battery requires a
Battery Discharge Indicator (BDI). In some batteries the BDI will be
integrated into the battery. If the BDI is not integrated an external
BDI must be installed in a location that is easily seen by the driver.
In some applications there will be a GCT BDI and a data connection
to the truck.
The BDI displays useful information for the driver, along with error
codes. The default view shows the state of charge, the pack voltage,
and the current draw or charge.

The BDI will ash the red light and beep if it needs attention. The
following conditions will trigger the alarm:
• Overvoltage
• Undervoltage
• Over Temperature
• Under Temperature
• Low State of Charge
The truck operator should stay aware of the battery BDI while in
operation. When the battery gets low (<10%) the BDI will ash and
beep, signaling the battery must be charged. Once the battery is
empty it will cut power to the truck.
Charging Instructions
Batteries without internal chargers are charged either through
their main power connector (Euro or SB), a separate charge port,
or a charge port on the external of the truck. Make sure to use the
appropriate charge port when charging the battery.
Some of the smaller batteries have internal chargers. To charge
these batteries simply use the extension cord provided, and plug
the battery into a standard 110-120VAC outlet.
Use ONLY an approved and properly congured charger to charge
your SAFEFlex lithium-ion battery. Use of an unapproved or
incorrectly congured external charger may damage your battery
and void the warranty. The battery is designed for fast opportunity
charging and charges to specic voltage levels that may not be
programmed into your charger if it has not been approved or
properly congured.
Opportunity Charging
The battery is designed for opportunity charging, and plugging it in
whenever not in use (breaks, lunch, and after hours) will lengthen
the runtime and lifetime of the battery. It is strongly recommend
the battery be plugged in for charging whenever it is not in use.
Operating Temperatures
Standard operational temperatures for the battery are:
Discharge: -4°F - 131°F
Charge: 32°F - 113°F
The battery may have additional options such as internal heaters, if
you wish to operate outside these temperatures.
Storage Temperatures
Storage (<1 month): -4°F - 113°F
Storage (>1 month): 41°F - 68°F
In addition, make sure to turn the battery off while in storage or
while equipment is waiting for deployment. Refer to our extended
storage instructions when planning to store the battery longer than
1 month.
Troubleshooting
If there is an error code on the BDI, follow the appropriate
instructions.
Over Temp: Allow the battery to cool.
Under Temp: Allow the battery to warm.
Over Voltage: Allow the BMS to bleed down the excessively
high voltage.
Under Voltage: Charge the battery.
If the battery has cut power and there is no error code (as detailed
in the Battery Discharge Indicator section) turn the battery off for
30 seconds, then turn it back on.
