20V 10A Battery Testing Equipment

Product Overview

This battery testing system is designed for controlled charge, discharge, cycling, and data acquisition of battery cells and battery-related devices requiring outputs up to 20V and 10A. It combines 16-bit AD and DA resolution, independent channel control, four-wire voltage and current sensing, and a dual closed-loop constant-current and constant-voltage architecture. With 200W output available per channel, the equipment supports demanding laboratory evaluation while maintaining stated full-scale voltage and current accuracy of +/- 0.05%.

The unit is suited to battery R&D, cell validation, smart-battery evaluation, materials research, and engineering test laboratories that need repeatable electrical characterization. Constant-current, constant-voltage, constant-current/constant-voltage, and constant-power operating modes allow teams to build practical test protocols around charging, discharging, capacity, and cycle-life requirements. SMBUS, HDQ, and I2C hardware compatibility also supports workflows involving smart battery communications.

Built for continuous test programs, this system provides configurable operating protections, reverse-connection protection, power-loss data protection, TCP/IP communications, and up to 65,535 cycles. Fast 20 ms hardware current response to 10A and 100Hz recording help capture changing electrical behavior with dependable, reviewable test data under controlled environmental conditions.

Key Features

• Independent Eight-Channel Control: Each unit provides eight channels with independent control, allowing different cells or test profiles to run in parallel. This improves laboratory throughput without forcing all samples to follow one common schedule.

• 20V 10A Charge and Discharge Capability: Each channel supports 2.5V to 20V during charging and discharging, with a 20mA to 10A current range in both directions. The 200W per-channel output rating supports high-current work within the specified voltage envelope.

• Precision Dual Closed-Loop Regulation: Separate dual closed-loop structures for the constant-current source and constant-voltage source provide stable regulation. Voltage and current accuracy are specified at +/- 0.05% of full range, with 0.025% stability for both measurements and outputs.

• High-Resolution Electrical Measurement: 16-bit AD and 16-bit DA resolution support detailed command and measurement handling. Four-wire connections reduce the influence of lead resistance on voltage and current detection, while input impedance is at least 1MOhm.

• Fast Transient Response: Hardware responds to a current command of 10A in 20 ms. This capability helps the equipment follow programmed operating steps and observe cells during changing load conditions.

• Flexible Charge and Discharge Programs: Constant-current, constant-voltage, and constant-current/constant-voltage charging are available, alongside constant-current and constant-power discharge. Voltage, current, relative time, and capacity can each be used as cutoff conditions.

• Deep Cycling and Nested Test Logic: Programs can run from 1 to 65,535 cycles, with up to 255 steps in each cycle. Up to four nested cycle layers support more sophisticated repeated test sequences without reducing the test plan to a basic charge-discharge loop.

• Configurable Protection and Data Retention: Safety limits for voltage, current, and delay time can be set for each program. Exception protections monitor specified charge and discharge deviations, while power-loss data protection preserves valuable test records when an interruption occurs.

• Smart Battery Communication Support: Hardware is compatible with SMBUS, HDQ, and I2C protocols. Software supports the standard field-information commands defined by Smart Battery Data Specification Revision 1.1, with a one-second data reading frequency.

• Networked Data Handling: Ethernet 10/100M and TCP/IP communication integrate the equipment into networked test environments. Results can be output as EXCEL files, TXT files, and charts for engineering analysis and reporting.
