3. Parameters

Advantages

• Power feedback to grid with direct current bus efficiency ≥60%: Both charging and discharging is energy-saving which saves a lot of electric power expenses and air-conditioner fees.
• Channels can be connected in parallel: Channels can be connected in parallel to increase current testing range, through which current would be doubled by increasing quantity of channels. For example, if 2 channels of 5V100Aequipment are connected in parallel, output current can be as much as 5V200A, and also fulfill accuracy requirement, which can save cost and resources.4channels can be connected in parallel at most.
• CCCV charge: CC charge transfer to CV charge smoothly, without any impact, which can avoid the micro-shot circuit due to high temperature of peak current impact or to avoid PCB protection or second protection action caused by over-charging.
• Current soft start to avoid any impact.
• Current and voltage sampling is of high stability and accuracy: this equipment applied 16bit bipolar ADC/DAC unit, to ensure voltage sampling high accuracy and long-term stability.
• DCIR test function: Pick out the DC load resistance unstable cell, to avoid repeated test caused by poor contact terminals or terminal oxidation due to long time use.
• Dynamic load protection DL function: this insures no large current go through cause by bad connection, to protect efficiently battery, PCB, MOSFET or FUSE from damage.
• Voltage clamp function: when battery does protect action through charging process, voltage clamp to pre-set voltage can protect battery or PCB from damage.
• ECD & EVD protection: avoid battery active protection and stop charging or discharging in advance caused by substandard conditions.
• Testing steps can set record conditions by section to achieve intelligent data management.
