5 common Euler HiLoad EV faults — and how to fix each

1. HiLoad showing battery error after fast charging

Step-by-step fix:

1. Pack temperature too high.
2. Wait 30 mins, restart.
3. If recurring, the cooling fan in the battery pack has failed — warranty job (don't run with this fault, cells degrade fast).

When DIY isn't enough — book an ev.care technician for your Euler HiLoad EV

If a fault repeats after the steps above, if any dashboard error code is showing, or if you notice any unusual smell, heat, or sound from the battery pack — stop driving. Euler HiLoad EV battery and motor faults compound: a minor BMS imbalance left untreated can kill the whole pack inside 6 months.
