Li-ion batteries are protected from low temperatures and do not support charging in such conditions. If the lithium battery is used in a low-temperature environment, a heating box must be installed in the cabinet to increase the battery’s temperature. Once the low-temperature protection is removed, the battery can be charged.
Insufficient AC power or low voltage on the busbar prevents the battery from charging. To resolve this, site modifications to the AC power source should be made to ensure sufficient electrical load.
Incorrect charging voltage parameter settings can lead to low voltage on the busbar, preventing the battery from charging. Check the charging voltage parameter settings and adjust them according to the lithium battery manual.
A failure in the lithium battery’s charging circuit, such as a faulty contactor or fuse, prevents charging. Inspect the charg ing voltage parameter settings and adjust them as specified in the lithium battery manual.
If the lithium activation cable is not installed (used with hardware anti-reverse insertion frames), the battery may enter deep discharge protection. In this case, it cannot be activated even when the main power is restored. Ensure that the matching lithium-ion activation cable is installed when using anti-reverse insertion frames.
Incorrect float charge voltage settings prevent the lithium battery from fully charging. Check the float charge voltage settings and adjust them as per the manual’s recommendations.
The lithium battery may experience low discharge temperatures in cold environments. In such cases, install a heating system in the cabinet. Once the low-temperature protection is removed, the battery can be recharged.
A high discharge multiplier can strain the lithium battery. To address this, expand the number of batteries on-site to reduce the discharge rate for each battery.
