You're Worrying About The Wrong EV Batteries
- The concern about electric vehicle (EV) battery reliability is misplaced as modern EV traction batteries are showing low failure rates.
- Contrary to common belief, EVs rely on 12-volt batteries for essential functions like powering electronics and starting the vehicle.
- There are reports of 12-volt battery issues in EVs like Hyundai Ioniq 5, Kia EV6, Rivian R1S, and R1T, leading to recalls and redesigns.
- EVs charge and use their 12-volt batteries through a DC-to-DC converter, with different management strategies in place.
- Rivian faced challenges with its 12-volt battery system in the original R1S and R1T models, causing premature failures and other issues.
- Issues with 12-volt batteries extend beyond Rivian, with other manufacturers like Hyundai, Kia, Genesis, VW, Chevy, and Toyota facing similar challenges.
- Despite initial problems, newer EV models have shown improvements in managing 12-volt batteries, with automakers adapting and learning from past issues.
- As vehicles become more complex with additional power demands, the reliance on 12-volt batteries highlights a broader trend in the automotive industry.
- Automakers are moving towards dual-battery systems and optimizing low-voltage batteries to address the evolving power needs in modern vehicles, including EVs.
- The issues with 12-volt batteries in EVs are part of the learning curve of transitioning to new technology and features in the automotive sector.
