15. CAN-BUS CONNECTIVITY
The NexSys
®
iON battery has the ability to be integrated into an OEM industrial truck
CAN-Bus system which allows battery information to be displayed on the truck user
interface (Refer to Section 13: Battery Communication Interfaces with Charger, Truck
and Operator Interfaces for making the connection between the battery and the truck).
Please contact your local EnerSys
®
Representative for this option.
This option will require engineering consultation between EnerSys and the industrial
truck OEM to ensure correct data and functions are enabled.
16. ACTIVATION / DEACTIVATION OF BATTERY
The battery will deactivate automatically when a no load condition (<3Amps) is detected
for a default setting of 8 continuous hours to ensure that an unused battery is not deeply
discharged accidentally.
16. ACTIVATION / DEACTIVATION OF BATTERY (CONTINUED)
Activation:
ACTIVATE the battery for truck operation
using one of the external sources listed
below. The battery will automatically switch to the traction state (provided the pack is
not connected to a charger and there are no battery errors) applying power to the truck.
In all cases, a short press of ~0.5s is required.
• Activation via push button operator interface, CDI, BDI or Truck iQ™ dashboard
(Refer to Section 14: Operator Interfaces).
• Activation via External Key Signal (Refer to Section 13: Battery Communication
Interfaces with Charger, Truck and Operator Interfaces).
ACTIVATE the battery for charge operation
(when battery is OFF prior to plugging in)
An activation signal is sent to the battery when it is plugged into the charger. This allows
battery activation and charging even without previous activation of the battery by other
measures above (Refer to Section 17: Charging Battery).
NOTE: Shut Down at Low SOC
Once the battery falls below 0% SOC the CDI, BDI and/or Truck iQ™ device will send
both visual and audible alarms to the operator for 10 seconds before disconnecting
power indicating the operator to slow down and move the truck to a safe location (Refer
to Section 14: Operator Interfaces for details on other non-disconnecting SOC warning
levels).
Once this Low SOC level is reached, the battery can be reactivated to allow travel to
the nearest charger. If the product continues to be used, at 0% SOC, and the limited
capacity is depleted, the operator interface will again provide a 10 second warning
before disconnecting power and locking out. It is highly recommended to drive at slow
speeds and not to perform any additional lifts before having recharged the battery as it
may shut off again due to low SOC or reduced current limits. The performance in this
mode is very limited.
NOTE
: If the battery shuts down again when in the LOW mode and a simple press of
the activation button does not reactive that battery, EnerSys
®
personnel with a service
tool will be required to unlock the product.
Deactivation:
In order to turn the battery OFF press the push button on the CDI, BDI or Truck iQ
device for 3 to 5 seconds. Holding for longer may result in turning the pack OFF and
then back ON. The industrial truck should be shut down prior to deactivating the battery.
NOTE
: When turning the pack OFF there is a ~20s shutdown sequence in which an
audible alarm will be heard.
17. CHARGING BATTERY
The battery must only be charged by an EnerSys approved charger for Li-ion chemistry,
which is specially designed to allow CAN communication with the battery to control the
battery recharge. This ensures a safe and optimal operation of the system. All operating
instructions found in the User Manual of the charger must be followed.
NOTE
: Never attempt to charge using the connector from the battery to the truck.
The battery system is equipped with drive away protection that will disconnect the
traction power, disabling the truck if any battery charging plug is connected to charger.
This mitigates the risk of an operator accidentally driving away when the charger is still
connected which can cause chargers to be pulled from their mounted locations.
The battery should be charged in an appropriate environment (Refer to Section 3: Safety)
including a clean and dry environment keeping in mind the requirements of charging
location as described in the Charger User Manual.
The charge plug has embedded anti-arc contacts to reduce arcing while performing
inadvertent hot disconnect operations.
NOTE: The CAN enabled charge connector from the battery must be plugged into the
matching CAN enabled charge connector from the charger. Otherwise the charging will
not start as there will be no CAN communication between the battery and the charger.
Ensure that connectors are free of contamination prior to connecting.
Depending on the battery there is dual or single connector charging capability.
At present communication options such as Ethernet, PLC and remote lights cannot be
optioned on the charger.
Charging must be done with the battery inside of a vehicle except in the case of storage.
When in the industrial truck the battery must not be disconnected from the industrial
truck nor is it required to open lids and covers on the battery compartment.
