As summer quietly approaches, electric vehicles are entering their peak usage season. However, the high temperatures of summer not only bring driving enjoyment but also pose new challenges to the safety of electric vehicle batteries’ range. The health status and range capability of the battery have become core issues that every electric vehicle owner must closely monitor!
While the term “battery range” sounds simple and straightforward, it encompasses rich scientific principles. One particularly critical concept plays a decisive role in ensuring that electric vehicles operate safely and efficiently during the summer—SOC value.
SOC, short for State of Charge, refers to the battery’s state of charge. It is an important indicator of the remaining battery capacity, usually expressed as a percentage.The higher the SOC value, the more remaining battery capacity; conversely, a lower value indicates insufficient power. Understanding and mastering the SOC value is crucial for vehicle owners to reasonably plan charging schedules and ensure driving safety!
·Charging needs vary at different SOC stages. For example, when SOC is at 15%, the demand is 300KW, while at SOC 80%, the demand is only 25KW, and at SOC 95%, the charging demand is only 5KW.
· Different types of vehicles have different demands at the same SOC stage. This is mainly due to differences in vehicle usage, load, energy management strategies, and battery systems.
· Even vehicles of the same model may have different demands at the same SOC stage. This can be influenced by environmental factors such as time or temperature.
SOC value is crucial for electric vehicle usage. Let’s take a look at the benefits it can bring to vehicle owners:
·Reasonable charging schedule: By monitoring the SOC value, vehicle owners can better plan charging times to avoid affecting their trips due to insufficient power.
·Extend battery life: The battery’s lifespan mainly depends on its charge-discharge cycle count, depth of charge-discharge, operating temperature, and the battery’s chemical characteristics. The management of the SOC value directly affects these factors, thereby impacting battery life.
·Improve driving safety: During long-distance travel, understanding the SOC value can help vehicle owners plan charging stations in advance, avoiding getting stranded due to insufficient power.
To fully tap into the potential of the SOC value, whether in daily maintenance or targeted management during high summer temperatures, it is essential to strictly follow scientific principles and methods.SOC Maintenance Rules
1.Regular checks: Regularly check the vehicle’s SOC value to understand the battery’s charging status.
2. Plan trips reasonably: Based on the SOC value and trip distance, plan charging stations reasonably to ensure smooth travel.
3. Avoid extreme charging: Avoid keeping the battery at extremely low or high SOC states for extended periods to prolong battery life.
4. Use smart charging: Utilize smart charging devices that automatically adjust charging strategies based on battery status to protect battery health.
Summer Charging Tips
1. Cool down before charging: Before charging in summer, try to turn off the vehicle and let it sit for 10-15 minutes, waiting for the battery temperature to drop to normal levels before starting the charging process.
2. Avoid high-temperature periods: Preferably charge during the daily 06:00 to 10:00 and 18:00 to 23:00 “golden charging hours” and choose charging stations with shading facilities whenever possible.
3. Control charging amount: In summer, it is not recommended to charge to 100%; reaching 80%-90% is sufficient.
4. After long-distance travel: It is recommended to wait for more than 30 minutes, allowing the battery to cool down sufficiently before charging.
Summer is a time of frequent charging for electric vehicles. Properly managing the SOC value can not only enhance driving efficiency and safety but also effectively extend battery life. We hope every vehicle owner can enjoy cool driving in summer, keep their vehicles in optimal condition, and make every trip safe and pleasant!
