Power management and equipment configuration Power management in EV-based testing operations requires a fundamental shift in thinking compared to traditional testing setups. V2L-equipped vehicles eliminate the need for separate auxiliary battery systems, simplifying the testing setup while providing more reliable power. High-power V2L systems, theoretically offering between 7-11.5kW, can support comprehensive testing configurations including multiple scanners, computers, and climate control systems for sensitive equipment. Testing equipment should be configured with careful consideration of power requirements and physical placement within the vehicle. A typical 5G testing setup draws between 400-600W continuously, including scanner systems (150-200W), data collection computers (150-250W), and climate control for equipment (100-150W). Modern EVs with V2L capability can easily handle these loads while maintaining stable power output. Equipment mounting in EVs requires careful consideration, with particular attention to both testing authenticity and equipment protection. While the availability of frunk (front trunk) space in many EVs offers additional storage options, testing devices often need to be positioned to replicate real-world usage scenarios. Specifically, devices should be mounted to simulate typical subscriber behavior - such as a passenger holding and interacting with a device - rather than being placed in positions (like the vehicle roof) that might yield artificially optimized results but don’t reflect realistic user conditions. Temperature management is a critical concern in testing setups. Equipment racks should be shock- mounted to protect sensitive testing gear, and proper ventilation must be maintained to prevent overheating. The interior mounting of testing devices not only better simulates real-world conditions but also allows for more effective cooling through the vehicle’s climate control system. When planning the mounting configuration, proper weight distribution remains crucial for vehicle handling and safety, while ensuring all equipment remains accessible for monitoring and adjustment during testing sessions.
Environmental impact of EVs’ usage for network testing: carbon emissions analysis Network drive testing operations have significant environmental impacts that can be substantially reduced through EV adoption. Based on data from the International Energy Agency (IEA, 2023) and the EPA’s vehicle emissions database, we can quantify these benefits: Traditional drive testing vehicle emissions (average based on observations of NT projects performed using TEMS™ solutions): • Average daily testing distance: 200 km • Annual testing days: 250 (typical working year) • Fuel consumption while driving: 10L/100km • Idle fuel consumption: 2L/hour (EPA Idle Fuel Consumption Database, 2023) • Diesel CO2 emissions: 2.68 kg CO2 per liter (EPA Emissions Factors, 2023) EV testing emissions (varies by region): • Energy consumption: 20 kWh/100km (based on real-world EV fleet data) • Grid electricity CO2 intensity (2023 data from respective agencies): • European Union: 0.231 kg CO2/kWh (European Environment Agency) • United States: 0.386 kg CO2/kWh (EPA eGRID) Annual CO2 reduction potential: • EU operations: 13,673 kg CO2 (83.7% reduction) • US operations: 11,891 kg CO2 (72.8% reduction)
