Product Description

100V 30A 2CH Battery Charging and Discharging Testing Machine

 

Equipment principle and composition
1.1 Upper computer:
The upper computer software is the main human-computer interaction tool, and the functions of starting, stopping, pausing, and connecting devices can be achieved through the upper computer; The data on battery aging is mainly collected and processed by the upper computer, and the test results required by the customer are output.
 
1.2 Median machine:
The central computer is the device control management software, and the capacity, power, and other parameters of battery testing are calculated by the central computer.


1.3 Bidirectional ACDC+LLC isolated DCDC:
When charging, this function module takes power from the power grid and adjusts it through bidirectional DCDC before charging the battery; When discharging, this functional module will feed back the energy transmitted from bidirectional DCDC to the power grid.


1.4 Bidirectional DCDC (Buck/Boost): 
This functional module is a non isolated DCDC, which outputs the current and voltage values required for battery charging and discharging, i.e. constant current charging, constant voltage charging, and constant current discharging are all executed by this module.


Scope of application
An integrated charging and discharging cycle testing system for lithium-ion battery packs, including electric tools, solar energy storage, torsion bikes, scooters, electric bicycles, electric motorcycles, and household energy storage. It is used for functional testing and monitoring of charging and discharging data.


Equipment environmental requirements and technical parameters
3.1 Whole cabinet power supply:AC voltage 380V ± 10% ,frequency:50Hz±10%;
3.2 Ambient temperature:-10~45ºC;
3.3 The environment is free from strong vibrations, corrosive gases, and flammable and explosive gases.


Function Introduction
4.1 Charging and discharging function: With constant current and constant voltage charging and constant current discharge functions, it can charge and discharge the battery and record its capacity;
4.2 Check voltage protection: Check whether the charging and discharging protection of the battery is effective by charging and discharging the battery;
4.3 Security protection: anti reverse connection protection function, power-off data protection, supporting continuous testing, voltage upper and lower limit setting protection, and safety discharge current protection;
4.4 Adopting high-frequency isolation method, the entire system is isolated from the power grid to ensure safe and stable operation of the system;
4.5 The bidirectional ACDC module adopts space vector modulation technology and digital control, resulting in high voltage utilization and smaller current harmonic diversion;
4.6 Can achieve internal conversion of dual channel charging and discharging energy;
4.7 The DCDC module adopts advanced PID regulation technology and multiple protection mechanisms to ensure the stability of equipment operation;
4.8 Energy feedback (DC bus efficiency ≥ 93%): Energy feedback type, battery discharge energy can be fed back to the power grid;
4.9 Seamless switching of constant current and voltage mode, without any voltage and current surge. It can effectively prevent the battery from experiencing heat concentration due to peak current, which can lead to pole ear powder shedding;
4.10 The voltage and current are sampled using a four wire system, with high voltage sampling accuracy and good long-term stability;
4.11 Single pass has independent operation capability and supports multi-channel parallel output;
4.12 Supports battery barcode input, with traceable historical test data.
