Phase 1 | Sany electric heavy truck energy-saving driving tutorial

Similar to fuel vehicles, electric vehicles also need to drive energy-efficient.Energy-efficient drivingIt is a complex system engineering related to people, vehicles, roads, etc., and the technical level of the driver to control the vehicle is the key link that affects the energy consumption of the vehicle.

Drivers operate safely and energy-efficiently with minimal energy consumption, and driving habits affect the range of energy consumption of the vehicleUp to 30%Energy-saving driving technology is an energy-saving measure with low cost, quick effect and obvious effect.

The energy-saving driving tutorial will be displayed in three phasesIssue 1: How to achieve energy-efficient driving at different driving speeds

1●Get off to a smooth start

The larger the opening of the electric door at the start, the faster the acceleration,Electricity consumption is directly proportional to accelerationThe faster the acceleration, the greater the power consumption, you need to try to start slowly, add the power gate slowly, control the opening of the electric throttle, when the opening of the electric throttle is small and slow, although the speed is relatively slow, but the power consumption is much less.

When starting, it is necessary to overcome the acceleration resistance caused by the inertia of vehicle motion, and if the driver can achieve gentle control of the acceleration pedal in a slow acceleration mode, the acceleration resistance of the vehicle can be effectively reduced.Slowly press the electric door to about 50%., so that the vehicle moves slowly, and the control power of the observation instrument is better within 200kW.

Mastering the driving skills of the vehicle starting is very important for the power consumption of pure electric vehicles, for the sake of safety and energy saving,Be careful not to rush when starting。

2●Drive at a constant speed

In energy-saving operation, like traditional fuel vehicles, pure electric vehicles also advocate driving at a constant speed, and the opening of the electric valve changes smallly, which is good for safety and energy saving. After the starting speed is completed, the motor speed should be controlled according to the road driving conditions, and the electric valve should be used to control the vehicle gently and smoothly, rather than letting the electric valve always push the car. When driving at a constant speed, try to keep the instrument power within 200kW to avoid frequent acceleration and deceleration.

Let the vehicle maintain a high speed, low speed, power balance and constant speed driving state, in order to achieve the best power saving effect, but also to control the maximum speed, the faster the speed, the greater the power consumption. Generally, with the same tire diameter and gear ratio, the energy-saving driving speed of the model with a large rear axle speed ratio is slower than that of the model with a small speed ratio.The high-roof model of Sany electric heavy-duty truck is the economic power consumption area in the range of 50-70km/h, and the flat-top model is the economic power consumption area in the range of 45-60km/h.

(The speed of the 5.143 ratio model is controlled within 65 yards, the speed of the 5.286 ratio model is controlled within 60 yards, the speed of the 5.571 ratio model is controlled within 55 yards, and the speed of the 5.92 ratio model is controlled within 50 yards)

3●Vehicle acceleration

Slow acceleration gradually increases the travel of the accelerator pedal, and it is advisable to keep the electric gate in1/3~2/3In the range, when gradually increasing the travel of the accelerator pedal, the power of the drive motor controlled by the instrument is observedWithin 200kwThe smaller the operating power, the lower the corresponding power consumption per 100 kilometers.

When the vehicle accelerates, if you press the accelerator pedal too quickly and too violently, it will not only lead to an increase in power consumption, but also easily cause accidents.If the vehicle accelerates excessively, the torque generated by the motor will be excessive, causing the high-voltage system circuit to consume too much power, resulting in increased power consumption.
