Refer to the appropriate Application Note available from www.discoverbattery.com
for the set up of closed-loop parameters and integration with specific brands of
solar inverter-chargers, solar charger controllers, mobile inverter-chargers, and
industrial chargers.
10.3.2 Open-Loop Charging
Open-loop charging is a method of charging where the battery and charger do not
communicate. The charger must be configured manually with appropriate settings
for open-loop charging.
For charging parameters, refer to Table 3-1, AES LiFePO
10.3.3 When to Charge the Battery
• Opportunity charging is OK: Charging the battery after every use will not reduce
its cycle life.
• Partial State-of-Charge is OK: If the battery SOC is greater than 10% at the end of
discharge, it does not require an immediate charge.
• Charge if below 10% SOC: If the battery is discharged below 10% SOC, it must be
charged within 24 hours to avoid permanent damage to the battery. Otherwise,
irreversible damage to the battery cells will occur in a very short period of time.
• Low charge current extends life. Charging at 50% of nominal current or lower
helps extend the battery cycle life.
Charge within the proper temperature range. Ensure that charging is within
the charge temperatures specified in Table 3-3, AES LiFePO
Specifications.
• The battery must be charged within 24 hours if it has been discharged below 10%
SOC. Otherwise, irreversible damage to the battery cells will occur in a very short
period of time and void the warranty.
10.4 Charging Profile
Charge with a Lithium charge profile matching the specifications for the AES
LiFePO
battery.
4
Standard open-loop charging for the battery should include both Bulk and
Absorption phases.
Refer to Table 3-1, AES LiFePO
parameters.
Refer to the appropriate Application Note available from www.discoverbattery.com
for the set up of closed-loop parameters and integration with specific brands of
inverter-chargers and battery chargers.
