Renault recently sent out an email to all Zoe and Kangoo EV owners to tell them that portable chargers “should only be used in rare cases to enable you to continue your journey” and that “Renault strongly advises customers not to use a portable charger as the primary charging option as it may detrimentally affect the battery resulting in costly repairs which are not covered by your vehicle warranty”.
What Renault is effectively saying here is that if you admit to using a portable charger and there’s a fault with your vehicle’s battery, they will use that fact against you to not replace or repair the battery under warranty, leaving the vehicle owner with a massive repair bill.
Many EV owners prefer using a portable charger for a variety of reasons:
- They’re renting so don’t want to spend money to install a dedicated charging unit on a landlord’s property.
- Kill two birds with one stone. Why buy a charger for home and a charger for portable use when a portable charger can do the job of both?
- Charging at 2kWh from a 10A power socket overnight is more than enough for their needs and portable chargers cost less than a wallbox.
Other manufacturers like Tesla and Hyundai ship their vehicles with a portable charger and don’t make the same claims Renault do, so what has Renault found that makes them threaten customers with losing their warranty is they use a portable charger?
If Renault has proof of portable chargers damaging their vehicle batteries, they should make that public so current and potential EV owners are better informed. Without that evidence, it seems like Renault just want to increase sales of “Z.E. Ready certified” wallboxes with unnecessary fear mongering.
