7. OPERATION
The Battery BMS prevents battery operation outside of specified operating
conditions. Make sure to understand each of these protections and how to set
up the system accordingly. Refer to
Table 2-4
.
DLB Protection Specifications
.
NOTICE
Intentional bypassing of the BMS to operate the battery outside maximum and
minimum limits voids warranty.
7.1 Low Voltage Cut-Off
The low voltage cut-off, as controlled by the application, should be programmed
at or above the Low Voltage Disconnect Voltage value given in
Table 2-1.
DLB
Electrical Specifications
. This ensures that the load will disconnect before the BMS is
forced to enter low voltage protection.
NOTICE
Storing or leaving the battery at 0% SOC will lead to irreversible damage.
7.2 BMS Hibernation
The BMS will enter hibernation mode if there is no charge or discharge activity
detected for 10 minutes, or if the battery triggers low or high voltage protection
three consecutive times. During this time, the BMS will disconnect the internal
SSR and Bluetooth functions will be disabled. This protection helps safeguard the
battery from becoming over-discharged.
The battery will exit hibernation mode by:
•
Applying a charge current.
If the battery is in low voltage protection and
hibernation mode a small charge current will reactivate the BMS.
•
Applying charge or discharge current.
If the battery is not in low voltage
protection but is in hibernation mode a charge or discharge current will
activate the BMS.
7.3 State of Charge
A Bluetooth App for mobile devices provides real-time access to the battery state-
of-charge, voltage, operating current, temperature, status and a diagnostic report.
Search for Lithium Blue Battery Monitor App on Apple’s App Store or Google Play.
A voltage-based battery meter that is designed for lead-acid batteries will not
provide an accurate state of charge (SOC) for lithium. Use a battery meter that
measures current, rather than voltage, for lithium batteries.
