Tips to Take Care of Your VinFast VF 8 EV Battery During Summer Weather

MARKHAM, Ontario--(BUSINESS WIRE)--Summer’s soaring temperatures, can pose certain challenges for electric vehicles (EVs) like the VinFast VF 8. Therefore, it's crucial for owners to understand how to properly care for the battery, especially in the face of extreme heat.

This guide will delve into how hot weather impacts EV batteries and provide practical tips for maximizing your battery's lifespan.

EV Batteries in Hot Weather

EV batteries, primarily lithium-ion, are sensitive to temperature fluctuations. While cold weather affects range, high temperatures can significantly accelerate battery degradation. Heat increases the rate of chemical reactions within the battery, leading to faster breakdown of its internal components. This translates to decreased capacity, reduced range, and potentially a shorter overall lifespan.

Best Practices for Summer EV Battery Care

  1. Limit Fast Charging: While fast charging is a convenient feature, it generates more heat than standard charging. During hot weather, it's advisable to limit the use of fast chargers, especially immediately after driving. Give your EV battery some time to cool down before plugging it in to prevent excessive heat buildup.
  2. Don't Charge to 100% Regularly: While it's tempting to always charge your EV battery to 100%, it's best to avoid doing so regularly. Most manufacturers recommend keeping your battery's state of charge between 20% and 80% for daily use. This helps to minimize stress on the battery and prolong its lifespan.
  3. Plan Your Charging: Leverage the VinFast app's Trip Planner feature to plan your charging stops. Opt for charging stations with shaded parking or indoor facilities whenever possible. This can significantly reduce your battery's exposure to high temperatures during charging sessions.

    Also, schedule your charging sessions during cooler hours, such as overnight, to minimize heat-related stress on the battery.
  4. Utilize Preconditioning: Many EVs, including the VinFast VF 8, offer preconditioning features. The VinFast app allows you to remotely pre-cool your cabin before you even step inside your vehicle. This not only enhances comfort but also ensures that your battery starts at an optimal temperature, minimizing the strain caused by heat.
  5. Regular Maintenance: Follow VinFast’s recommended maintenance schedule for your EV's battery. This typically includes periodic checks for any signs of damage or wear and tear. Addressing issues early on can prevent them from escalating and causing long-term damage to the battery.

In addition, VinFast offers a comprehensive warranty on the VF 8's battery, providing owners with peace of mind and protection against unexpected battery-related issues. The 10-year unlimited kilometer battery warranty and the 10-year/200,000 km new vehicle warranty underscore VinFast's commitment to quality and customer satisfaction.

With the VinFast VF 8's advanced technology and comprehensive warranty, you can confidently embrace the future of electric mobility and enjoy worry-free driving throughout the year.
