Installation Guide
7.5 Storage
Systems should be stored out of direct sunlight in compliance with the following temperature conditions:
Minimum Storage Temperature -20°C / -4°F
Maximum Storage Temperature 45°C / 113°F
Batteries should be put into storage at 80% SOC and checked monthly to ensure the SOC does not fall below 20%.
At 20% SOC the battery will self discharge in approximately 2 months.
▲ CAUTION!
Do not store a discharged battery. Recharge battery after every
use. Batteries that have self-discharged to a severely discharge
state are not recoverable.
8. Protection & Faults
• BMS generates faults when maximum operating limits are reached.
• BMS sounds a buzzer when fault limits are triggered.
• BMS monitors the following information for faults and warning:
1. Cell module voltage
2. Battery current
3. Battery temperature
▲ NOTE!
Refer to device technical specication tables at the end of this
manual for Fault Limits.
CORRECTIVE ACTIONS
High Temperature
• Stop discharge or charge
• Leave the battery to cool
Low Temperature • Stop discharge or charge
High Voltage
• If charging, stop the charge
• Conrm proper charge algorithm is being used
Low Voltage
• Do not discharge the battery - if any discharge current is detected, this will
force the battery into Low Voltage Fault
• Charge the battery in Low Voltage Recovery - if no charge current is
detected within 2 minutes the BMS will set the battery to OFF
Over Current • Reduce current
Low SOC
• Stop discharge
• Charge the battery
Inaccurate SOC displayed by
Power Conversion system
• Battery voltage based SOC calculations provided by Power Conversion
systems do not work properly with Lithium battery voltage.
• Use a Discover CAN Bus Battery Discharge Indicator (p/n 950-0005, 950-
0006, 950-0007) to display accurate SOC. To communicate accurate SOC
in a closed loop Power Conversion system use a Discover LYNK Commu-
nications Gateway device (p/n 950-0015)
