Battery Charger/Discharger

Product Overview

The Battery Charge-Discharge Tester is a comprehensive testing device integrating constant current discharge, intelligent charging, and charge-discharge cycles. It is used for regular battery group inspections and the revitalization of degraded batteries. Suitable for telecommunications, base stations, and power sectors, it is also applicable for testing and cyclic activation of traction battery groups in various types of forklifts, golf carts, and trains.

Product Features

Our product utilizes custom nickel-chromium alloy resistors as the load source. Low resistance; allows for greater current discharge, with a custom appearance that enhances power density. High precision; accuracy is maintained within ±0.001Ω, ensuring a more stable discharge process as a load source. Low temperature coefficient; minimally affected by temperature coefficients, with strong environmental adaptability. Current shock resistance; capable of withstanding current shocks, quickly responding to large current surges for a more reliable discharge process.

Intelligent Chip Control: Smartly controls the discharge process, automatically adjusting with the decline in battery voltage to ensure constant current discharge. Real-time collection of single battery cell voltage is displayed in a curve format for easy evaluation and analysis. Meanwhile, it intelligently analyzes the battery voltage status and provides assessments. It calculates the conversion between discharge capacity and discharge hour rate for optimal battery state evaluation. Multiple threshold values can be set for intelligent judgment.

7-inch Large LCD Touchscreen: Featuring a large-sized touchscreen with a resolution of 1024x600, it allows for direct on-screen clicks and is easy to operate. Strong anti-interference capability.

The LORA wireless single battery monitoring module (optional): compatible with 2V/6V/12V single battery voltage monitoring. Each wireless monitoring module can simultaneously monitor 6 batteries, requiring only 1/6 of the modules compared to monitoring a single battery voltage per module (48V requires only 4 monitoring modules), making the wiring operation of wireless modules more convenient.

The automatic discharge current calculation feature: Built-in discharge coefficients for each hour rate, capable of automatically calculating the required discharge current based on the nominal capacity of the battery being tested and the desired discharge rate.

During the charging and discharging process of the battery, real-time detection and display of individual cell voltages: The host screen presents the changing trajectory of individual cell voltage bar graphs, supports data table display, and can automatically present cells with high and low voltages in real-time, helping you quickly analyze the trend of individual cell changes.

Charge/Discharge Curve Review: Allows for a review of the battery pack's voltage and current curves during the discharge process.

Data Transfer: The main server is configured with a USB drive for data backup. Data analysis software can parse the data and supports report generation.
