1500V 300A Battery Pack Testing: Regenerative Cycling and BMS Integration
Battery pack testing requires more than charging and discharging. Engineers need to evaluate capacity, energy output, internal resistance and cycling performance while monitoring how the battery responds to changing operating conditions.
The Brilliance Technology BT1500V300AC2 Battery Pack Testing System combines two-channel charge-discharge testing, regenerative energy feedback and BMS communication to support battery development and production testing.
High-Voltage, Two-Channel Testing
The specified configuration provides a charge-discharge voltage range of 40–1500V, with support for charging from 0V. Each channel offers up to 300A charge-discharge current and a maximum output power of 450kW.
This operating range allows test procedures to be configured around the voltage and current requirements of different battery modules and packs. Test settings should always remain within the battery’s approved operating limits and the equipment’s rated operating envelope.
Key specifications include:
| Parameter | Specification |
|---|---|
| Output channels | 2 |
| Charge-discharge voltage range | 40–1500V; supports charging from 0V |
| Charge-discharge current | Up to 300A per channel |
| Maximum output power | 450kW per channel |
| Voltage measurement and control accuracy | 0.05% FS |
| Current measurement and control accuracy | 0.05% FS |
| Minimum data recording interval | 10ms |
| Cooling method | Air cooling |
FS means full scale; it should not be interpreted as a percentage of the measured reading.
Regenerative Energy Feedback
During discharge, the system can recover electrical energy for reuse instead of dissipating it entirely as heat. Recovered energy can supply other electrical loads or support charging on another channel.
This regenerative approach can reduce the net electricity required for repeated charge-discharge cycles. Actual energy savings depend on the test profile, battery characteristics and operating conditions; they are not a fixed percentage for every application.
Programmable Test Profiles
The system supports constant-current and constant-current/constant-voltage charging, together with constant-power, pulse and operating-condition simulation modes. Discharge modes include constant current, constant resistance, constant power, pulse and operating-condition simulation.
These functions support several battery evaluation tasks:
- Capacity and energy measurement.
- Cycle-life testing.
- DC internal resistance measurement.
- Charge-discharge characteristic evaluation.
- Simulation of changing operating conditions.
Engineers can combine test steps into repeatable procedures and configure termination conditions using voltage, current, time, capacity and energy values.
BMS Communication and DBC Support
The system supports BMS CAN communication and DBC file import. With a compatible BMS and the appropriate communication definition, it can collect information such as pack voltage, pack current, cell voltage and temperature.
BMS values can be compared with measurements from the tester and used as conditions within a test procedure. For example, configured BMS thresholds can trigger a step change or stop condition.
Communication compatibility and the available signals should be confirmed for each battery project.
Test Data and Analysis
The software provides real-time monitoring of voltage, current, charge-discharge capacity and test-step status. Users can review historical records, compare curves and export results for further analysis.
A minimum recording interval of 10ms supports detailed tracking of test events. The specified current rise/fall time is no more than 5ms from 10% to 90% of full scale, with charge-discharge transition time no more than 10ms from −90% to +90% of full scale.
These timing specifications describe different functions: data recording, current response and charge-discharge transition should be assessed separately when planning a test.
Protection and Project Configuration
The specification includes grid-side and battery-side protection functions, configurable voltage and current limits, temperature-related protection and an independent emergency stop button.
Protection settings must be matched to the battery under test. They complement, rather than replace, appropriate test procedures and facility safety measures.
For project evaluation, provide Brilliance Technology with your battery voltage range, maximum charge-discharge current, required channel count, BMS protocol and intended test profiles. These details help establish a suitable testing configuration.
