Unlike internal combustion engines, where regular fuel-ups keep vehicles running, EVs rely on battery health and management to ensure consistent performance over time. This requires a level of precision that only high-quality, high-frequency telematics data can provide. Here’s why 1Hz telematics data—data sampled every second—is crucial for battery longevity and operational efficiency.
Why 1Hz Data Matters for Battery Health and Longevity
Electric vehicle batteries have a limited lifespan, generally rated at around 10,000 charge cycles, meaning that efficient battery usage is paramount for long-term fleet viability. Keeping the state of charge between 20% and 80% can help extend battery life, but ensuring adherence to this range requires accurate, high-frequency monitoring. At lower sampling rates, telematics solutions may miss crucial events, such as charge disruptions or spikes in energy draw. With 1Hz data, fleet operators receive a detailed, second-by-second account of battery performance, allowing them to intervene proactively to maintain optimal charging practices.
When the battery state of charge rises above 80%, charging becomes significantly slower, increasing the risk of heat buildup, which can accelerate degradation. With real-time data, fleet managers can monitor battery temperature and state of charge closely, ensuring the battery stays within safe limits to avoid premature wear. High-frequency data also alerts operators when a vehicle has been left plugged in for too long, a practice that, if not corrected, can gradually damage battery health.
The Role of 1Hz Data in Driving and Charging Practices
Driving and charging behaviors are two of the most influential factors in battery longevity. High-frequency telematics data provides fleet managers with insight into how driver behaviors impact battery life. For instance, frequent regenerative braking events recapture energy, which can reduce overall energy consumption and prolong battery life. 1Hz data tracks every instance of regenerative braking, helping operators understand how well drivers are utilizing this feature and where improvements can be made.
Similarly, 1Hz data allows fleet operators to analyze driving style and energy draw, identifying whether aggressive driving behaviors—such as rapid acceleration and heavy braking—are impacting battery health. By adjusting driving practices based on this data, fleet managers can optimize energy usage and minimize strain on the battery, supporting long-term performance and cost savings.
Long-Term Battery Degradation and the Need for High-Frequency Data
Battery degradation is a gradual process influenced by multiple factors, including temperature, charging frequency, and energy use patterns. With high-quality 1Hz data, fleet operators gain a modular and reliable data set that provides the insights necessary to monitor long-term degradation trends. This level of data granularity allows for predictive maintenance, helping fleet managers identify when a battery is beginning to underperform and allowing them to address issues before they escalate.
Maintaining battery longevity requires constant attention to operating conditions, from temperature and state of charge to the frequency and quality of charging sessions. For EV fleets, high-frequency telematics data at 1Hz enables the precision and reliability needed to manage these conditions effectively. By investing in advanced telematics solutions like GoMetro’s EV-CAN, fleet operators not only protect their battery investments but also gain a powerful tool to support sustainable, cost-efficient fleet operations over the long term.
