What are the categories of battery tester?

Battery tester is indispensable equipment in crucial fields such as power, communications, petrochemicals, finance, railways, and military, primarily used for monitoring battery voltage, constant-current discharging, capacity analysis, and other key performance parameters. With the continuous advancement of battery technology and the expansion of application fields, the types of battery testers have also become increasingly diverse to meet testing needs in different scenarios. Below are the main classifications of battery testers:

I. Classification by Testing Functions

1. Basic Battery Testers: These testers have relatively simple functions, mainly used for monitoring basic battery performance such as voltage and internal resistance, suitable for routine maintenance and simple testing.

2. Comprehensive Battery Testers: Comprehensive testers offer more comprehensive functions, including basic voltage and internal resistance testing, as well as constant-current discharging, capacity analysis, online monitoring, etc., suitable for comprehensive assessment and maintenance of batteries.

3. Intelligent Battery Testers: Intelligent testers integrate advanced sensors, controllers, and data processing technologies, capable of real-time monitoring of battery status, providing early warning and alarm functions, and offering maintenance suggestions through data analysis. Additionally, some intelligent testers support remote monitoring and data analysis, significantly improving testing efficiency and accuracy.

II. Classification by Testing Objects

1. Single Cell Battery Testers: These testers are used to test the performance of individual batteries, such as voltage, internal resistance, and capacity, suitable for small batteries or scenarios requiring precise testing of individual battery performance.

2. Battery Pack Testers: Battery pack testers are used to test the overall performance of battery packs, including total voltage, charging and discharging currents, and capacity, suitable for large battery packs or scenarios requiring testing of battery pack overall performance.

III. Classification by Testing Methods

1. Offline Testers: Offline testers require the battery to be disconnected from the system for testing, suitable for deep discharging tests or scenarios requiring accurate measurement of battery actual capacity.

2. Online Testers: Online testers can perform real-time monitoring of battery status while the battery pack is in online discharging, equalizing charging, floating charging, etc., suitable for scenarios requiring real-time monitoring of battery status and prevention of potential failures.

IV. Classification by Application Fields

1. Communication Battery Testers: Primarily used for battery testing in communication base stations, data centers, and other communication fields, requiring testers with high precision, high reliability, and remote monitoring capabilities.

2. Electric Vehicle Battery Testers: Electric vehicle battery testers are used to test the performance of batteries for electric vehicles, including battery pack voltage, current, capacity, temperature, etc., requiring testers with high precision, high safety, and high-current testing capabilities.

3. Energy Storage Battery Testers: Energy storage battery testers are used to test the performance of batteries in energy storage systems, including battery pack voltage, current, capacity, energy efficiency, etc., requiring testers with high precision, high reliability, and long-duration testing capabilities.

In summary, battery testers are classified in various ways, and users should select the appropriate tester type based on actual needs. When selecting, in addition to considering the tester's functions, precision, and reliability, factors such as ease of use, after-sales service, and price should also be considered.
