Rate voltage or named voltage of the battery. Generally this value is the same as discharge plateau.

Was this helpful?

Each location on the tester that tests a single device is called a channel.

Was this helpful?

This is a specified voltage value or voltage range. Battery's voltage will change less than other voltage ranges as it charges or discharges. This value could be obtained from the differential capacity curve - the peaks of the curve represent the charge and discharge plateau. Discharge plateau could be called nominal voltage of the battery.

Acronyms

ACR: Alternative Current Resistance. aka, Impedance.

Battery impedance is a combination of internal resistance and reactance where internal resistance + reactance, or (L+ C), equals impedance when using an AC stimulus. The internal resistance of a battery is made up of two components: electrical, or ohmic, resistance and ionic resistance. For battery applications, most meters use 1000Hz, ±5mA as stimulus.

CAN: Controller Area Network. A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but is also used in many other contexts.

Neware battery tester series EVT 7000 features CAN capability, supporting information parsing acquired by BMS.

DCIR: Direct Current Internal Resistance. aka DCR. DCIR of batteries is the resistance of current flowing through the battery, with the standard unit of measurement called the ohm.The value of DCIR is not fixed, and varies depending on multiple factors, such as battery materials, electrolyte concentration, temperature, and depth of discharge.

Neware battery tester series BTS 4000, BTS 8000, BTS 9000 support DCIR tests.

Products

Below are our major product series. For more details, visit our products page or contact our sales representative.

BTS 4000

This series is an updated version of BTS 3000. It provides higher data acquisition rates up to 100Hz to enable reliable DCR (Direct Current Resistance) measurements. It also features a faster system output response for improved accuracy.

BTS 8000

BTS 8000 is designed for EV (Electric Vehicle) drive cycle simulation, providing even faster system response than the BTS 4000. Multiple current ranges are available to ensure high current or power capabilities.

BTS 9000

This series is our sophisticated series for battery or material research solutions. It is characterized by a data acquisition rate up to 1000Hz, an accuracy of 0.02% FS (Full Scale) and a minimum pulse width of 400us (microsecond) which can be utilized for GSM or other rapid pulse tests.

BTS ES

In most cases, discharged power from batteries is released as heat. Our ES (Energy Saving) system has energy recovery capabilities, allowing for improved efficiency.

EVT 7000

EVT 7000 improves on the EVT 6000 and provides more reliability and efficiency in a smaller footprint.

BVIR

BVIR provides portable ACR (alternative current resistance) and voltage testing solutions for batteries. It complies with IEC 61436:1998, using 1 kHz alternative current stimulus signal for ACR measurement.

We provide not only the above presented products, but also calibration systems, system integration solutions, testing services and software development such as BIS (Battery Information System) to manage battery production information and LIMS (Laboratory Information Management System) to manage testing activities in a laboratory.

System Architecture

All Neware testers could be deployed via TCP/IP, providing flexibility, data security and integrity. For some agile testing solutions and calibration, RS232 or RS485 protocol is also used. Our setting in this manual is for the equipment deployed via TCP/IP. And in our current and latter software edition, we are going to combine testing activities control functions and all system management functions like calibration into one.
