FH series can be used for charging and discharge maintenance of the whole set of high voltage battery systems in large warehouses or OEMs, by means of FB discharge without generating new heat source while working. It makes testing efficient, energy efficient and safe. It is suitable for centralized maintenance of wide voltage range and high-power lithium battery packs.
Application
Lithium battery packs maintenance in after-sales, OEMs, Service Providers, storage & transportation.
Feature
Energy Feedback: two-way flow energy, automatic energy direction adjustment; battery pack feeds energy back to three-phase power grid while charging & discharging, DC bus efficiency≥93%, save electricity bill.
High-power Isolation Transformer: stable system isolated from power grid with fast transformation of output current which has no overshoot.
DC/AC module adopts space vector modulation technology; digital control ensures high voltage utilization ratio and lower current harmonics shunt.
DC/DC module adopts advanced PID control technology; multiple protection mechanism ensures its stable running.
Supports communication with external units and receiving external information and control instruction.
CCCV Charging: there is no voltage and current impact during the charging process.
High precision and dynamic range ADC/DAC unit for bettery voltage sampling accuracy and good long-term stability.
DCIR DC Load Impedance Test: detect the load impedance within ms during battery charging and sudden unloading real time, and identifying DCIR unstable batteries.
Voltage Clamp: voltage can be clamped at the set voltage to prevent damage to the protection plate when battery protect action or equipment goes wrong during charging.
ECD&EVD Protection: avoid and selects battery which is in the state of active protection and stops charging or discharging in advance caused by unqualified conditions.
