The cold wave is coming, and the Sany electric mixer truck keeps warm like this!



At present, winter has been fully entered in China, especially in most parts of the north, and the night temperature has been as low as below zero. In a low-temperature environment, I want to be electricMixer trucksThe life is longer and the normal daily use is guaranteed, which is inseparable from careful care and maintenance.

Now the Sany electric mixer truck winter car guide is presented, in the power battery, system components, car to explain, very dry dry goods, recommended collection, it is worth repeatedly circulating and watching

01Power battery: scientific charging, pay attention to warmth

At present, the power system of pure electric mixer truck is mainly lithium-ion battery, due to its chemical characteristics, the low-temperature performance will be weaker than that at room temperature, which is not suitable for high-current charging and discharging, therefore, low-temperature vehicles will cause some changes:

First of all, the discharge capacity of the power battery (large battery) is reduced, the power of the vehicle is weakened, if the ambient temperature exceeds the storage range, the vehicle (equipment) must take corresponding measures for storage, otherwise it will lead to irreversible damage or damage to the battery, and even have safety risks. If the vehicle continues to be in a low temperature environment and does not operate, it is recommended to park the vehicle in a thermal insulation environment when not in use, and it is best to put it into storage in time.

2. In the low temperature environment, it is recommended to plug in the gun to charge before driving or wait for heating in situ, increase the minimum temperature of the power battery to 5 °C, improve the energy recovery efficiency, and charge in time when the SOC of the vehicle is less than 30%.

In addition, in the low temperature environment, high-current charging will cause damage to the power battery (large battery) system, which will reduce the service life of the power battery, in order to protect the power battery system, the charging power will be adjusted according to the temperature of the power battery, and the charging time will increase by 0.5-1h.

02System: timely inspection, refuse frost damage

1. Wiper glass water and antifreeze need to be replaced in time when it is 2 years or 60,000 kilometers, and the freezing point of the selected antifreeze should generally be more than 10 °C lower than the local temperature.

2. In the case of low temperature, the capacity of the low-voltage 24V battery (small battery) is reduced, and attention should be paid to keeping the positive and negative binding posts clean and free of snow and ice to ensure the reliability of vehicle starting. If you need to park for more than 1 month, you need to disconnect the negative terminal post of the low-voltage battery to prevent the vehicle from being unable to power on due to the low-voltage battery feeding.

03Winter driving: reasonable control, energy-saving range extension

In winter, the climate is harsh, and the vehicle is affected by operating conditions, ambient temperature, ramps, etc., which has a great impact on energy consumption, but through reasonable operation and energy-saving driving, energy consumption can be appropriately reduced and driving mileage increased.

1. Charging in a low temperature environment, open the key, you can blow warm air in the cab while charging, to avoid severe cold and freezing.

2. When encountering bridge decks, back-sun areas, and slippery roads with rain and snow, you should drive slowly, step on the accelerator lightly, and lightly step on the brakes to minimize the braking to prevent the vehicle from skidding caused by floating water and thin ice, causing the vehicle to lose control. Keep a sufficient safety distance from the vehicle in front when driving, and do not grab the traffic light to improve driving safety.

3. In the case of low temperature, the viscosity of the steering hydraulic oil is enhanced, and the steering oil pump will make a "buzzing" sound when playing the direction, and the steering wheel is activated in a small range intermittently for about 10 minutes to warm up the steering power system before starting.

Instead of waiting until something goes wrong with the car and then worrying, it is better to pay attention to the details to maintain it at ordinary times. The above electric mixer truck winter maintenance cheats, escort your winter car, please collect it.
