Battery Chamber Safety Options

We provide a full selection of safety options for reliability and abuse testing of batteries. Each environmental chamber is designed with safety in mind. Safety features may be incorporated into CSZ test chambers and tailored to the various hazard levels (0 - 6) to help mitigate potential risks. If you don't see the option you need on this list, contact us and we will provide you with the solution you need to meet your specific test requirement.

Battery Chamber Safeety Options

Explosion Resistant Light

Explosion Resistant LightA fully enclosed explosion-rated light is available to prevent ignition source.

Sheath HeatersTemperature Limited Sheath Heaters are fully-encased temperature limited sheath heaters. The surface temperature of the heaters is limited to minimize spark potential. The limits set to below the auto-ignition temperature (AIT) of gases expelled.

Redundant High/Low Limit & Alarm A redundant product high/low temperature limit & alarm is an added level of safety to prevent overheating. A thermocouple sensor attaches to each battery cell and is designed to shut down the chamber if the temperature exceeds established limits. For example: If the test maximum temperature is +85°C, the temperature limit will be set at +90°C. This will trigger the light stack/alarm and fresh air blower and send signal to lab safety system and shut down the chamber.

Programmable Door LockThe Programmable Door Locks prevents entry either during tests or after an event. An example of the set function: Lock upon profile start, unlock upon profile end, or lock with an alarm.

Light Stack with Audible AlarmA light stack and alarm is a programmable option used to indicate the current status of the chamber and/or test. Example: Red:  alarm (not running), Yellow: idle/standby, Green:  good (running). The audible alarm can activate together with the red light during an alarm. They can also be programmed for different functions.

Dry Air Purge System

Dry Air Purge System Dry Air Purge System allows the user to select a constant Compressed Dry Air that purges into the chamber cabinet during testing. It can also be manually turned on at the end of the test, to purge the cabinet. The purge could be for approx. 60 seconds before stopping the chamber to remove any potential outgassing before opening the chamber door.

GN2 PurgeGN2 Purge, allows the user to select a constant Nitrogen to purge the chamber cabinet during testing. It can also be manually turned on at the end of the test, to purge the cabinet. The purge could be for approx. 60 seconds before stopping the chamber to remove any potential outgassing before opening the chamber door.

Fresh Air BlowerFresh Air Blower can be manually turned on at the end of test, to purge the cabinet. This is achieved by taking in fresh lab air and cycles for a duration of time adequate to completely exchange “contaminated” air with fresh air.

Fire Suppression SystemThe Fire Suppression system utilizes CO2 to “manage” the thermal runaway of a battery fire. It will be used to cool the environment and inert the cabinet. This activates when a decrease in oxygen is detected, an audio/visual alarm, and/or triggering the customer’s lab safety system. Fire detection tubing detects flame and (heat), it bursts, allowing the cylinder’s valve to open and release the CO2 suppression agent.

Gas MonitorGas Monitor & Alarm can be activated when H2 or CO is detected but also when a decrease in O2 is detected. If it is triggered, the chamber will sound an alarm, send a signal to customer's fire safety system and/or turn on fire suppression system. This system can monitor the presence of additional specified gases and can be interlocked to the controller to shut down the chamber. .

Heated Explosive Relief VentThe Heated Pressure (Explosive) Relief Vent/Blow-Out Port allows the chamber to release pressure inside the chamber during a thermal runaway (when cells start to rupture or propagate). It will open, allow release, and then slides back down into place. The outer perimeter of the port is heated so that it does not freeze during cold testing.
