Hefei Tower Intelligent Lithium Battery Management System Application

In the Hefei Tower intelligent lithium battery management system, ordinary lithium batteries and intelligent lithium batteries are mixed.

1.System configuration:

1.1 Charger DC voltage (54.6V).

1.2 On-site configuration of two 48V200ah ordinary lithium-ion and two 48V100ah intelligent lithium-ion (self-management with temperature compensation mode)

2. Self-management mode:

2.1 When connected in parallel, the intelligent lithium-ion battery enters the constant voltage discharge state according to the power system bus voltage change, realizing that the intelligent lithium-ion battery mains discharges with priority when the utility power goes out;

2.2 The minimum backup time after energy storage discharge is not less than 3 hours or the depth of discharge is not higher than 90%;
