Guide to the use of electric vehicles in winter, how to make lithium-ion batteries active? Posted by benzoenergy.com
With the transformation of automobile electrification, consumers' acceptance of pure electric vehicles has gradually increased, and pure electric vehicles on the market have become more and more popular, but at the same time, the shortcomings of pure electric vehicles have also been exposed.
Nowadays,
spontaneous combustion incidents of pure electric vehicles are
frequent, and even if the technology is constantly updated and iterated,
it is still difficult to stop. In addition to safety issues, battery
life and charging issues are also the biggest headaches for car owners.
Especially in the low temperature conditions in winter, the battery performance
decreases, the battery life decreases significantly, and the charging
speed becomes slower, which makes many car owners a headache. So how can
the problems encountered by pure electric vehicles in winter be
improved?
At present, the
common power batteries on the market mainly include ternary lithium
batteries and lithium iron phosphate batteries. As a chemical material,
its most suitable working temperature is about 20℃-25℃. If the
temperature is too high or too low, it will cause damage. The decline in
the vitality of lithium-ion batteries not only affects the cruising
range, but also reduces the efficiency of charging and discharging.
As the activity of lithium decreases, the charge-discharge rate of the battery also decreases. Active lithium-ion batteries can optimize the range of electric vehicles in winter.
For
pure electric vehicles pursuing intelligent technology, most of the
models have remote control functions. Based on this, the car owner can
start the battery preheating function through remote control before
using the car and before charging, so that the battery can be warmed up.
Achieve a suitable temperature; secondly, the location of the vehicle
is also particularly critical. Avoid parking in an open-air parking lot
as much as possible. Choosing an indoor or a basement can better keep
the battery temperature at a suitable level.
In
addition, in winter, pure electric vehicles consume a certain amount of
battery power when turning on air conditioning and heating. As we all
know, the source of air-conditioning heating in traditional fuel
vehicles in winter is engine waste heat, while the source of
air-conditioning heating in pure electric vehicles is batteries.
Therefore, to a certain extent, the winter endurance of pure electric
vehicles will also be affected by the opening of the air conditioner.
Replacing
air conditioning and heating with smart methods is the most effective
solution. Similarly, most pure electric vehicles are equipped with seat
heating and steering wheel heating. After turning on this function, not
only the body temperature rises more obviously, but also the power
consumption is lower than that of the air conditioner. The heating
effect is excellent, so don't worry about battery life.
Develop
good driving habits and maintain safe driving at a constant speed are
also important for optimizing endurance performance.
Compared
with traditional fuel vehicles, electric vehicles start quickly and
accelerate faster. This is also a big advantage that many consumers love
electric vehicles. But in winter, you should try to avoid sudden
acceleration, because this will form a large current. Such a sudden
high-current discharge is not only harmful to the health of the battery,
but also consumes a large amount of power, resulting in a rapid decline
in battery life. Therefore, when driving an electric vehicle in winter,
the acceleration should be gentle and it can be driven at a constant
speed. Try to avoid sudden acceleration and continuous high-speed
driving. This can effectively improve the endurance of the vehicle and
extend the service life of the battery.
In
addition, in the driving process, car owners can also reduce the usage
rate of smart products such as car navigation audio reversing images,
turn off unnecessary functions, and optimize vehicle mileage.
Although
these suggestions cannot completely solve the problem of winter
endurance anxiety, these suggestions can also greatly optimize the
vehicle's endurance range and are a temporary effective solution. In the
long run, battery technology will continue to develop and make
breakthroughs in the future, and the energy and life of batteries will
also be improved. By then, electric vehicles may no longer be affected
by cold temperatures and mileage anxiety, and charging speed will not be
a problem.
