1. Protection and Faults

6.5 Storage

Systems should be stored out of direct sunlight under the following temperature conditions:

Systems should be put into storage at 80% SOC and checked monthly to ensure SOC does not fall below 20%.

At 20% SOC the battery will self discharge in approximately 2 months.

7. 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

High Temperature

Low Temperature

High Voltage

Low Voltage

Over Current

Low SOC

▲ 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.

▲ NOTE!

Refer to device technical specification tables at the end of

this manual for Fault Limits.

CORRECTIVE ACTIONS

• Stop discharge or charge

• Leave the battery to cool

• Stop discharge or charge

• If charging stop the charge

• Confirm proper charge algorithm is being used

• 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

• Reduce current

• Stop discharge

• Charge the battery

• 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 Communications Gateway device
