Therefore, it is recommended to avoid frequent acceleration and deceleration, drive the car
on a flat dry road; if necessary, turn off high-power electric devices such as, air conditioning,
so as to reduce the power consumption of high-power electric devices and increase the
driving range.
■
When the car is driven in the first time or it is kept for a long time, SOC displayed on
the dashboard may be deviated. It is recommended to fully charge the battery for SOC
calibration.
■
To keep the power battery in optimal conditions, please charge regularly the power
battery fully with a charge device (it is recommended for charge at least once a week).
■
When the power battery is about to be fully charged, it will enter the slow charge mode.
The ending charge time will be extended
■
At high or low temperature, the charge capacity of the power battery will be decreased
and the charge time will be longer, which is a normal phenomenon. It is recommended
to use a high-power charge post or a professional charge cabinet for quick charge.
■
Under the low-temperature high battery level status, the charging current is low based
on the low-temperature characteristic of battery. Therefore, to shorten the charging
time, it's recommended to charge your vehicle at low battery level in low-temperature
environments.
■
With low-temperature low-power AC charging method, the battery features low
self-heating amount due to limitation of charging power. To promote the charging
amount, the battery heater will start at that time so that the heating power consumption
will increased compared with that with DC charging method and meanwhile the
charging time will be longer, which is a normal charging symptom in low-temperature
environments.
■ To improve the vehicle operation experience, it's recommended to immediately charge
your vehicle at completion of use, in order to improve the charging performance due to
relatively high battery temperature. If the battery temperature is low, the battery will be
probably charged quickly to the completion status to avoid damaging the battery.
■
When the A/C system is turned on during the low-temperature charging, the
performance of the battery temperature control system and the charging performance
of your vehicle will be influenced.
■
During driving process, if the temperature of the power battery is too high, its charge
and discharge capacity will gradually decreased, so that the battery is cooled down,
which is a normal phenomenon. If the temperature of the power battery is increased
continuously, the overheating indicator on the dashboard will be turned on; at the time,
must park the car until the battery overheating indicator is turned off. If the overheating
indicator is not turned off after a long time or is always on, it is recommended to
contact BYD Auto Authorized Service Station for maintenance.
■
The battery heater is a slow-to-warm heater. For short-time driving, the performance of
the battery temperature control system will be not obvious and the power consumption
will be increased and the driving range will be shortened. For long-time driving, the
battery heats up intrinsically to continuously increase its temperature. In such case,
the battery heating need for your vehicle is low. To better improve your vehicle
operation experience, the battery temperature control system is mainly functioned to
guarantee the low-temperature charging performance.
