Key requirements include the use of a Battery Management System (BMS) integrated with the battery pack, ensuring compliance with IEC 62619 certification. Batteries must be installed in sealed compartments or external locations, with ventilation to prevent gas ingress into habitable areas. Protective devices, such as fuses or circuit breakers, are mandatory to prevent overcurrent and short circuits. Installations must also adhere to exclusion zones, maintaining a 300mm distance from fuel lines, and use dielectric shielding if this distance cannot be achieved. Monitoring systems must display the battery’s state of charge and voltage, and all components must meet specified IP ratings for environmental protection. Non-compliance can result in safety risks and legal issues, making adherence to these standards critical for manufacturers and installers.
Installation Guidelines for Lithium Batteries
Lithium batteries must be installed in sealed compartments or external locations, ensuring proper ventilation and compliance with AS/NZS 3001.2:2022. Exclusion zones and protective measures are mandatory for safety.
3.1 Permissible Locations for Battery Installation
Lithium batteries in caravans must be installed in specific locations to ensure safety and compliance with AS/NZS 3001.2:2022. They cannot be placed in habitable areas unless sealed in an enclosure. Permissible locations include external compartments, behind walls, under beds, or in cupboards, provided these areas are vented to the outside. Batteries must be secured in a sealed box or container to prevent gas ingress into living spaces. External installations require protection from physical impact and weather, with appropriate IP ratings. Cables entering the battery compartment must be sealed with cable glands to maintain integrity. Installations under seats or in cupboards are allowed if they meet sealing and ventilation requirements. Proximity to fuel lines and storage areas must adhere to exclusion zones, ensuring safe distances or proper shielding. Compliance with these guidelines ensures both safety and regulatory adherence.
3.2 Exclusion Zones and Safety Distances
Exclusion zones and safety distances are critical for lithium battery installations in caravans to prevent hazards. Metallic services, such as gas, diesel, water, and fuel lines, must be at least 300mm away from the battery surface containing terminals. This applies to both horizontal and vertical planes. If maintaining this distance is not feasible, lines must be shielded with dielectric material to prevent accidental short circuits.
