What is the optimal remaining charge level for BYD Han EV?
3 Answers
It is best to charge when the remaining battery level is between 0-50%, as this allows the power battery to achieve its maximum cycle lifespan. BYD Han's charging modes: Scheduled charging (charges the vehicle at the time set by the customer). For detailed setup instructions, refer to the scheduled charging function settings on the combination meter. Instant charging (charging begins immediately after plugging in the charging interface or through manual operation). BYD Han EV charging methods: Portable household AC charging; Single-phase/three-phase AC charging via charging station (when equipped); DC charging via charging unit.
I've been driving the BYD Han EV for a while now, and I find it's best to charge when the remaining battery is between 20% and 30%. Don't wait until the battery is almost empty to charge, as that can easily damage the battery's lifespan. The characteristics of lithium batteries mean they prefer moderate charging and discharging, so try not to frequently charge to full, especially to 100%, as it can accelerate aging. My daily commute uses about 15% of the battery, so I charge twice a week at home using a slow charger, which is convenient and cost-effective. The BYD app can set charging reminders, and I set it to 25%, so it notifies me without having to constantly check the screen. Cold winter air can affect the range, so I leave a bit more battery as a precaution. After driving like this for almost three years, the battery health is still very stable with no noticeable degradation. Charging time is also convenient; plug it in at night, and it's fully charged and ready to go by morning.
From a maintenance perspective, I charge my BYD Han EV between 20% and 80% remaining battery. Deep discharging lithium batteries puts stress on internal materials and accelerates degradation, so I avoid going below 10%. I also don't charge to full capacity - the 70%-80% range is the sweet spot for keeping the battery young. In daily driving, I monitor the range data displayed on the central screen and look for charging points when it drops below 30%, using slow charging mode as the safest option. Before long trips, I charge to around 90% and top up to 60% at highway service areas. The Han EV's battery management system supports this habit to extend lifespan. Temperature changes must also be considered - in hot weather I control charging temperature to prevent overheating. This maintenance approach saves battery replacement costs and ensures driving safety.
