6. Battery management system (BMS)
7. Surge protection
8. Quality certification

These features represent various perspectives on safety in battery design, with some emphasizing the importance of advanced technology while others focus on fundamental protective mechanisms. The debate around whether routine testing or regulation is more critical in safety assurance also influences the design and manufacturing of battery packs.

1. Short-circuit protection:
   Short-circuit protection prevents excessive current flow, which can lead to battery failure or fire. This safety feature prevents damage to the pack and surrounding devices. Features like fuses or circuit breakers are commonly used in designs to interrupt the current flow during a short circuit. According to a 2021 study by Zhang et al., the implementation of reliable short-circuit protection has reduced incidents by approximately 30%.

2. Overcharge protection:
   Overcharge protection eliminates the risks associated with charging beyond the recommended voltage. This feature typically involves a monitoring system that disconnects the charger once the battery reaches its voltage limit. For example, lithium-ion batteries are often equipped with integrated circuits specifically designed to halt charging, thus mitigating risks associated with thermal runaway. Research from the Institute of Electrical and Electronics Engineers (IEEE) highlights that overcharge protection mechanisms can extend battery lifespan by up to 40%.

3. Over-discharge protection:
   Over-discharge protection prevents the battery from being drained beneath a safe level. Discharging beyond this point can permanently damage cells, resulting in performance degradation. A typical feature includes a built-in cutoff switch that activates when voltage falls below a predetermined threshold. A report by the Battery University notes that over-discharge protection significantly enhances the reliability and efficiency of rechargeable battery packs.

4. Temperature regulation:
   Temperature regulation manages the thermal environment of the battery pack. High temperatures during operation can lead to safety risks such as swelling, leakage, and combustion.
