Quick Summary

Want your EV battery to last? Avoid these five common mistakes:

  1. Draining the battery to 0%

  2. Overcharging or leaving it plugged in too long

  3. Ignoring software updates

  4. Relying exclusively on DC fast charging

  5. Skipping regular service for brakes and coolant

Read on to learn why these habits matter—and how to take care of your EV the smart way.

Top Five Mistakes

1. Letting Your Battery Get Close to 0%

Why It’s a Problem

Allowing your EV to fully deplete its battery can cause long-term degradation. Lithium-ion batteries prefer partial cycles—deep discharges stress the system and reduce overall capacity.

What to Do Instead

Try to keep your charge between 20% and 80% for daily use. Think of it like healthy eating for your battery—avoid the extremes.


2. Overcharging or Leaving It Plugged In for Days

Why It’s a Problem

Topping up to 100% and leaving it there—especially in warm weather—puts strain on battery chemistry. It’s a myth that “full is always best.”

What to Do Instead

Charge to 100% only when prepping for a longer trip. If your Kia lets you schedule charging or set a limit (many do), use it!


3. Skipping Software Updates

Why It’s a Problem

Modern EVs, including Kia models like the EV6 and Niro EV, rely on software for battery management, driving efficiency, and safety features. Outdated software can cause reduced performance—or missed enhancements.

What to Do Instead

Stay up to date with Kia’s Over-the-Air (OTA) updates, or ask about software checks during your regular service visits.


4. Using Fast Charging All the Time

Why It’s a Problem

DC fast charging is super convenient—especially on road trips—but frequent use generates heat and wears the battery faster than regular Level 2 charging.

What to Do Instead

Use Level 2 home charging as your daily go-to. Reserve DC fast charging for when you're exploring beyond Victoria (Tofino road trip, anyone?).


5. Ignoring Brake Service or EV-Specific Maintenance

Why It’s a Problem

Regenerative braking in EVs means you use your traditional brakes less—but that doesn't mean they're maintenance-free. Rust buildup or dried components can become serious (and expensive).

What to Do Instead

Book regular inspections for:

  • Brakes

  • Coolant systems

  • Tire wear (EVs are heavier!)
