If your battery gauge displays that you have a significant amount of power remaining and then it suddenly dies, it is a likely symptom of a degraded battery. Lithium-ion batteries differ from nickel-cadmium ones in that they power your device at full capacity until the battery runs out of juice.
To best manage your batteries for long-term success, look instead for ways to gain more actionable insights, allowing you to pinpoint opportunities to reduce battery degradation and increase the lifespan of your fleet.
Remember that increased heat generation then causes the battery to wear out faster, again sparking a cycle of degradation. Real-world example: EVs with a degraded battery charge, accelerate, and regeneratively brake more slowly. 3. Degraded controls
Recharging your lithium-ion battery after 20% to 30% of use helps you increase the chances of extending your battery’s life. The one exception is that once a month, it is recommended to let your battery run down to about 5% capacity before recharging.
Smart Charging Practices: Charging habits significantly influence battery health. For instance, constantly charging the battery to 100% or letting it run down completely before recharging can accelerate degradation. Instead, aim to keep the battery’s state of charge between 20% and 80%.
This means that over time, a fully charged battery won't take you as far as it initially did. Similarly, in battery energy storage systems (BESS), battery degradation can limit the amount of energy that can be stored and delivered, impacting the overall efficiency of the system.
