EP401 V2

EV Battery Charge & Discharge Equipment

About EP401

The EP401 V2 is a battery pack module integrated charge-discharge machine designed based on the characteristics of lithium-ion batteries used in electrical vehicles. It can efficiently perform the charging, discharging, and balancing of battery pack modules, thereby enhancing the efficiency of battery pack maintenance.
  • Supports charging and discharging maintenance for various battery types
  • Utilises advanced charging and discharging testing technology to avoid interference with the BMS system
  • Supports a maximum of 72 channels for cell voltage collection and 12 channels for temperature collection
  • Automatically determines charging and discharging operations
  • Wide voltage design with built-in multiple charging and discharging modes to meet the voltage and current requirements of various battery pack modules, ensuring safety while improving charging and discharging efficiency
  • Reverse polarity, overtemperature, short circuit, overcurrent, fan failure, overvoltage, overcurrent, etc. will be warned to ensure hardware safety
Charge/discharge test
Adopting a wide voltage design, it is suitable for charging and discharging tests of battery modules of different voltage levels. Supports various lithium batteries and nickel metal hydride batteries.
Single Unit and Terminal Voltage Collection
Supports real-time acquisition of pack terminal voltage and individual cell voltage.
Single Battery Core Protection
Cell current and voltage protection thresholds can be set to prevent overcharge and over-discharge.
Terminal Charging and Discharging Protection
Supports overvoltage, undervoltage, overcurrent, output short circuit, reverse connection protection and overtemperature protection.
Parameter Setting
General mode can quickly start charging and discharging by setting a few parameters, while expert mode can set more detailed parameters.
Data Visualization
During the charging and discharging process, the voltage of each single cell, terminal voltage, terminal current, the charging and discharging status, the charging and discharging capacity, etc. are monitored in real time.
History Records
Automatically saves historical charging and discharging records, supporting both curve and bar chart data display formats. Historical data can be exported as Excel files to a USB drive or shared as PDF files via email or QR code for data overview.
Online Upgrade
Supports online device upgrades without the need for local upgrades using a USB drive.
