Battery Storage
Your Yukon Trail Electric Vehicle is equipped with lead acid batteries. All batteries will self-discharge over time. The
rate of self-discharge varies depending on the ambient temperature and the age and condition of the batteries.
A fully charged battery will not freeze in winter temperatures unless the temperature falls below -75° F (-60° C). For
winter storage, the batteries must be clean, fully charged and disconnected from any source of electrical drain. As
with all electric vehicles, the batteries should be checked and recharged as required or at a minimum of 30-day intervals.
Charger Operating Instructions
1) Always use a grounded outlet. If using an extension cord, be sure and use a grounded 3-wire 12 AWG cord to avoid
excessive voltage drops.
2) The charger will then turn on and experience a short LED indicator self-tests for approximately 2 seconds. If connected to a
battery pack, a trickle current will be applied to the charger until a minimum voltage is reached. If charger is waiting to be
connected to a battery pack and being used in an off-board application, the charging algorithm number will be displayed for
approximately 11 seconds and then display an under-voltage fault (the fault will disappear when plugged into the battery.)
3) When a minimum battery voltage has been detected, charger will enter the bulk charging constant-current stage. The length of
charge will vary depending on how large and how depleted the battery pack is, the ambient temperature, and the input voltage.
If the ambient temperature is too high, charge power will be reduced to maintain a maximum interval temperature. If the input
AC voltage is low, charge power will be reduced to avoid high input currents.
4) At the time the battery is at approximately 80% state of charge, the bulk stage is then completed and an >80% charge notification
is given. In the next phase, known as the absorption or constant-voltage phase, the last 20% of charge will be returned to the
battery. If the vehicle requires immediate usage, charging could be terminated at this point. However, it is recommended to
wait for 100% charge notification to ensure maximum battery capacity and life.
5) A low current “finish-charge” is lastly applied to return and maintain capacity.
6) The battery is then completely charged. You may now unplug the charger from AC power. If kept plugged in, the charger will
automatically restart another complete charge cycle if the voltage drops below a minimum voltage or 30 days has passed.
7) If faults occurred at anytime during the charging process, a fault notification is given by flashing RED with corresponding code.
Some errors are serious and may require human intervention to fix the problem and then reset the charge by disconnecting AC
power for at least 15 seconds. Others may automatically recover when the fault condition is eliminated. To indicate which
error occurred, a fault notification will flash RED a number of times, stop, and then repeat. [1 FLASH] Battery Voltage High:
auto-recover [2 FLASH] Battery Voltage Low: auto-recover [3 FLASH] Charge Timeout: the charge failed to complete in the
allotted time. This might indicate a problem with the battery pack, or that the charger output was reduced due to high ambient
temperatures. [4 FLASH] Check Battery: battery pack could not be trickled charged to the minimum level required for initial
charge. May indicate one or more cells in the battery pack are damaged or shorted. [5 FLASH] Over-Temperature:
auto-recover. Charger has shutdown because of high internal temperature. Typically indicates no sufficient airflow for cooling.
[6 FLASH] Fault: an internal fault has been detected. After disconnecting AC power for at least 15 seconds, if Fault 6 is again
displayed, the charger must be taken to a qualified service depot.
