Device specific advantages

Energy feedback (standard sine wave feedback energy, best efficiency 90%): energy feedback type, charge and discharge two-way are energy-saving, can save a lot of electricity consumption, while saving a lot of energy energy generated by the cost of air conditioning electricity.

CCCV charging: charging process CCCV no gap transition, no any voltage current impact. It can effectively prevent the protection action and the secondary protection action of PCB caused by the peak current of the battery due to the heat concentration of the polar ear depowdering or the micro-short circuit producing the island effect or the overshoot phenomenon.

The current and voltage sampling stability is good and the precision is high: high precision, high dynamic range ADC/DAC unit, high voltage sampling accuracy and good long-term stability.

IDUser management consists of three parts: permission management, role management and user management. The administrator can set administrative permissions for each functional module of the software, and set multiple user IDs according to the permissions of the operator

DL Dynamic Load Protection Function: Effectively protects the battery in the charge and discharge, prevents the battery fire and effectively avoids the current shock caused by the loosening of the connector, and effectively protects the electronic components of the battery from being damaged by the shock current, such as MOSFET, FUSE

Voltage clamp function: During the charging process in the battery protection action or equipment abnormal, the voltage clamp position in the safe voltage to prevent battery or battery pack protection plate damage.

The test step can set the record condition in sections and implement the intelligent data management record.

Support BMS CAN communication function: real-time acquisition of BMS system total voltage, total current, single core voltage, temperature and other data, and CDS voltage and current data to do synchronous comparison, set BMS voltage and current temperature and other data to meet certain conditions, the main channel steps to stop or convert, specific reading information provided by the customer related information.

A custom set of signals is supported. The user can customize the name according to their own requirements and data records. By adding "sub-signal quantity" as the protection parameter, the protection

Parameter can be set multiple, and the result can generate a new decision condition by calculating the operator "maximum value, minimum value, difference value, mean value,-,×," function relation
