Regenerative Battery Tester Supplier for ESS, UPS and Data Centre Battery Testing
Bidirvolt supplies regenerative charge/discharge battery testers for ESS packs, UPS battery strings and industrial battery systems, with grid energy feedback, programmable test modes and exportable test records.
What a Regenerative Battery Tester Does
A regenerative battery tester applies controlled charge and discharge profiles to battery packs or battery strings. During discharge, usable energy is returned to the facility grid instead of being converted into heat by a resistor bank.
This makes the system suitable for long-duration ESS battery testing, UPS battery capacity tests, battery aging programs and factory acceptance testing where heat, noise and energy cost matter.
The tester records voltage, current, power, capacity, energy, cycle data and grid-side feedback metrics so engineers can build repeatable acceptance records.
Core Working Path
- Battery pack or UPS battery string connects to the DC input terminals.
- Control software runs CC, CV, CP, CR or dynamic charge/discharge steps.
- The DC bus is monitored for voltage, current, power and protection limits.
- Discharge energy is converted back to AC and synchronized with the grid.
- Test data is logged for capacity, SOH, cycle aging and acceptance reports.
Regenerative Battery Tester Specifications Buyers Should Confirm
For an accurate quotation, the supplier needs more than a model name. Confirm the electrical range, test sequence, communication interface, grid connection and report requirements before selecting equipment.
| Parameter | Typical Options | Why It Matters |
|---|---|---|
| Battery voltage range | 100V-800V DC, extended range by project | Must cover minimum, nominal and maximum pack voltage. |
| Charge / discharge power | 50kW-500kW per unit, parallel operation optional | Determines test duration, current rating and grid capacity. |
| Test modes | CC, CV, CP, CR, pulse and dynamic profiles | Matches capacity test, cycle life, aging and acceptance procedures. |
| Communication | Modbus RTU/TCP, TCP/IP, optional BMS integration | Allows automation, pack data collection and remote monitoring. |
| Grid connection | Project-specific AC voltage, frequency and protection logic | Energy feedback requires safe grid synchronization and interlocks. |
| Reports | PDF, Excel, CSV and timestamped test logs | Supports FAT, SAT, maintenance records and quality files. |
Battery Charge and Discharge Test Modes
CC / CV Testing
Run constant-current and constant-voltage charge or discharge steps for capacity verification, pack balancing checks and battery acceptance testing.
CP / CR Testing
Use constant-power or constant-resistance discharge to simulate operating loads for UPS batteries, ESS packs and industrial battery systems.
Pulse and Dynamic Profiles
Build custom step sequences for aging, transient response, PCS interaction and application-specific battery cycling.
Cycle Life and Aging
Repeat charge/discharge cycles, record capacity fade and build SOH trend data for battery development or maintenance programs.
BMS Data Integration
Align tester data with BMS voltage, temperature, alarm and status information when project communication protocols are provided.
Report Export
Export voltage, current, power, capacity, energy, cycle count and event logs for FAT, SAT and quality documentation.
Regenerative Battery Tester vs Traditional Discharge Load Bank
| Dimension | Regenerative Battery Tester | Traditional Dissipative Load Bank |
|---|---|---|
| Energy handling | Returns discharge energy to the grid when conditions allow. | Converts discharge energy into heat. |
| Heat load | Lower room heat during long-duration battery tests. | High heat output, often requiring ventilation or extra cooling. |
| Test data | Records cycle, capacity, energy, power and grid-side feedback data. | Usually focuses on discharge load and basic electrical readings. |
| Best use | ESS, UPS battery strings, pack cycling, aging and factory tests. | Simple discharge tests where energy recovery is not required. |
| Site requirement | Needs suitable AC grid connection and protection coordination. | Needs heat management, airflow and safe exhaust planning. |
