Due to the particularity of the power mode of the electric heavy truck，It is also more susceptible to winter temperatures and rain and snow.，So that that capacity and the use efficiency of the battery are improve，It is easily affected by low temperature and drops.，However，There are always more ways than problems.。

In the current period，We will focus on the key points of electric heavy truck maintenance in winter.，Make 10 collation instructions，Exactly：Routine examination is indispensable.，Battery maintenance is critical。Coming up，Let's get to know each other.！

01

Keep in mind regular maintenance

Electric heavy truck，As a part of the heavy truck industry，It is more special than fuel vehicles.，Its winter maintenance needs more attention.。Coping with winter attendance，Rain and snow increased，From Sandian、Bearing、Tire，To the air conditioner、Headlights、Windshield, etc，Regular maintenance is well done.，Efficient attendance is indispensable。

  

02

Check the power in advance when driving

Before getting out of the car，Pay attention to check the remaining condition of the battery.，Let's go as full as possible.，Make sure you don't panic with the car.。And after each attendance，It is also necessary to check the allowance in time，When the battery is charged（SOC）Below 20%Time，Please charge it in time，Ensure sufficient power。

03

Check the tire pressure when leaving the vehicle.

In winter, due to thermal expansion and cold contraction，The tire pressure will also become low.，The rolling resistance of the tire increases，The range will also be significantly shorter.，It should be inflated in time，And that drive safety is ensured。

  

04

Change the antifreeze regularly

Liquid other than antifreeze shall not be added to the cooling system，It is recommended to use the original antifreeze of Hanma Technology.。

05

Check and replace glass water

In winter, the temperature is below zero degrees Celsius.，The anti-freezing winter glass water shall be replaced.，Or add the appropriate proportion of alcohol to the glass water.，The purpose of lowering the freezing point can be achieved.。

06

Route Planning Look Ahead

Affected by low temperature，Battery range is reduced in the winter.。So when using the car,，According to the actual transportation situation，Plan the daily operation route in advance as far as possible，Ensure maximum transport efficiency。

  

07

It's important to warm up for departure.

Before getting out of the car，Preheat the vehicle properly，Allow the battery to warm up to the optimum operating temperature，O as to ensure stable power output efficiency.。And after startup，Keep the speed constant for a while.，Stabilize all parts of the vehicle。

08

Charging after use needs to be done in time

After each use，The battery temperature is still within the proper range，Higher charging efficiency，Charging at this time can improve the charging efficiency，Reduce charging time。

  

09

The charging environment is exquisite.

According to the actual operation，Try to charge in a more comfortable environment。Hanma Science and Technology Charging Power Station，Full consideration of extreme environmental conditions，It can operate safely even in the cold winter.。

  

10

Battery storage is scientific

When the vehicle is idle，The battery shall be fully charged and stored in a leeward and warm place.，To protect the battery capacity。If it has been kept for more than 3 months，The battery shall be charged and discharged once，O as to ensure the normal use of the battery.。

Electric heavy truck，There are many benefits，Winter attendance，Be fastidious；

Drive safely，Don't be impatient，Efficient attendance，Steady win。
