No Canary’s Rental Battery Deactivation by Zero-Volt Discharging solution provides a fast, safe, and flexible answer to these challenges. The system enables the controlled discharge of battery modules to zero volts before mechanical treatment, significantly reducing risks during recycling. Its modular plug-and-play design allows quick installation and commissioning, making it suitable for both new and existing recycling facilities.

With short delivery times and a rental concept, the system supports recycling operators in scaling their processes without long project lead times or the need for extensive infrastructure changes. All modules are designed for easy transport via forklift or pallet jack, enabling rapid deployment directly at the required location, ideal when additional capacity is needed quickly. During the discharge process, residual electrical energy is recovered and fed back into the facility’s power network. Continuous monitoring of voltage, current, and temperature ensures safe operation throughout the entire process.

The system supports a voltage range from 0 to 1000 VDC and a discharge current of up to 100 A. The modular architecture consists of two main channels with a total discharge power of 42 kW per main channel and up to eight subchannels per main channel. Each channel is individually monitored, allowing precise surveillance of the discharge process. Safety is a central part of the system design. Integrated protection functions prevent over-discharge below 0 V and monitor the entire process for abnormal behaviour. An anomaly detection system identifies voltage drops and irregular patterns at an early stage to help detect potential risks such as cell overheating. Additional protection features include overvoltage, overcurrent and reverse polarity protection, as well as continuous temperature monitoring with alarm functionality. To ensure the safe and efficient handling of battery modules and packs, the system uses the No Canary Safety Boxes with quick connectors.

Once the discharge process is complete, the safety boxes are disconnected from the deactivation unit. They then remain connected to the battery modules or packs and are switched to short-circuit mode. The batteries are now ready for storage. Leaving the batteries in this condition for 24 hours prevents voltage relaxation after disconnection and reduces residual electrical energy.

No Canary’s Rental Battery Deactivation solution combines rapid deployment, flexible scalability, short delivery times and comprehensive safety monitoring to provide recycling operators with an efficient first step in the process of safely recycling lithium-ion batteries. The rental version has already been deployed at multiple recycling facilities and is currently operating in two active installations.
