IEC 62660 UN 38.3 Programmable High and Low Temperature Charge Discharge Test Chamber for Battery Testing
The High and Low Temperature Charge-Discharge Test Chamber integrates a high-precision battery tester with a high-temperature test chamber. Parameters can be configured via controller or computer software to perform charging and discharging tests on various batteries. This system tests battery capacity, voltage, and current, and conducts battery cycle tests including high-temperature life testing. When equipped with an optional temperature module, it captures charge/discharge data variations under different temperature conditions.
Compared to traditional linear equipment, it offers superior precision (default accuracy of 0.01% of range) and stable performance. The system features single-point control and utilizes dual closed-loop control with constant current source and constant voltage source for charge/discharge testing. Connectivity via Ethernet provides convenience and flexibility, allowing additional devices to be added through a switch.

| Application | To verify the electrochemical performance of power banks under different high and low temperature environments |
|---|---|
| Applicable Batteries | Suitable for finished power bank testing below 30V/5A |
| Applicable Standards | Non-standard customized |
| Test Requirements |
|
| Control Mode | Touch screen (PLC) + computer software control |
|---|---|
| Control Method | Temperature control mode + charge-discharge control mode |
| Heating System | Controller outputs signals through SSR solid-state relay for high-precision contactless switching control of nickel-chromium alloy electric heating wire. PID pulse width modulation controls SSR to automatically adjust heating power. |
| Cooling System | Adopts intelligent energy-saving refrigeration unit design with compressor-based refrigeration system. Uses cooling capacity servo control (BTHC) balanced temperature and humidity regulation. Automatically switches refrigerant flow according to operating conditions, cutting excess capacity during constant temperature for energy-saving operation. |
| Charge-Discharge System | Bidirectional ACDC module uses space vector modulation technology with digital control for high voltage utilization. DCDC module employs advanced PID regulation technology with multiple protection mechanisms for operational stability. Features minimal current harmonic shunting and independent channel control with four-wire current and voltage acquisition. |
| Chamber Structure | Equipment consists of controller and test chamber in left-right configuration. Test chamber is independently sealed area, isolated from exhaust and lighting zones, preventing flames, high-temperature gases, and leaked gases from spreading to other areas. |
