500V 500A 2 Channels Lead Acid/Lithium Battery Charge Discharge Tester

500V 500A 2 Channels Lead Acid/Lithium Battery Charge Discharge Tester

Equipment configuration list

Application and Function

• Application: mainly used for circle life testing and quality control of li-ion battery, lead-acid battery, Ni-Cd battery, NiMH battery and so on in production line or in lab. 
• Support battery circle life testing, capacity testing, charging characteristic testing, discharging characteristic testing, charge retention capability testing, charge and discharge efficiency testing, over charge or over discharge rate affordability testing. 

Working Environment and Technical Parameters

• Power supply: AC 380V±10%, frequency: 50HZ±5%. Maximum input power of the whole cabinet: 315.8 KW（2CH）
• Working temperature: 0 - 45℃.
• Humidity: less than ≤ 95%R.H (non-condensing).
• No severe shake, no corrosive gases, no flammable or explosive gases around.
• Resolution: AD 16 bit

Advantages

• Power feedback to grid with direct current bus efficiency ≥90%: Both charging and discharging is energy-saving which saves a lot of electric power expenses and air-conditioner fees.
• 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 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.
• User management includes authority management, role management and user management. Managers can set management permissions for each function module of the software, and set multiple user IDs according to the operator's permission requirements.
• Voltage clamp function: when battery does protect action through charging process, voltage clamp  to pre-set voltage can protect battery or PCB from damage.
• Testing steps can set record conditions by section to achieve intelligent data management.
• Each channel has a built-in CAN and RS485 communication module to support BMS CAN communication function: collect the total voltage, total current, single cell voltage, temperature and other data of BMS system in real time, and make synchronous comparison with HRCDS voltage and current data. When setting BMS voltage, current and temperature and other data to meet certain conditions, the steps of the main channel will stop or convert, and the specific reading information will be provided by the customer.
• It supports user-defined signal sets. Users can customize the setting name according to their own needs and data recording requirements. By adding "sub semaphore" as protection parameters, multiple protection parameters can be set through the operators "maximum value, minimum value, difference value, mean value, +, -,×,÷, and, or, exponential variance, sine and cosine "function and other numerical relations are calculated, and the obtained results can generate new judgment conditions
