What is on the left side of the dashboard of a new energy vehicle?

The left side of the dashboard of a new energy vehicle includes the speedometer, tachometer, and oil pressure gauge. Speedometer: The speedometer is a digital instrument that operates through the engagement of the counter drum gear with the worm gear on the speedometer drive shaft, causing the counter drum to rotate. Its characteristic is that when the upper drum completes one full rotation, the lower drum rotates 1/10 of a turn. Tachometer: The tachometer is generally located within the instrument panel, symmetrically placed alongside the speedometer. It works on a magnetic principle, receiving pulse signals generated when the primary current in the ignition coil is interrupted, and converts these signals into a displayable rpm value. Oil Pressure Gauge: The sensor of the oil pressure gauge is a piezoresistive sensor, which is threaded into the engine oil pipeline. The oil pressure pushes the contact piece to move along the resistor, changing the resistance value and thereby affecting the amount of current passing through the gauge to the ground.
Back when I drove a new energy vehicle, the left side of the instrument cluster was typically where the speed was displayed. It looked like a large dial with numbers ranging from 0 to the maximum speed, showing you in real-time how fast you were going. This is super important for safety, as speeding can easily lead to loss of control. Additionally, in new energy vehicles, it might incorporate electric elements, such as displaying the remaining range or power output, letting you see whether your current energy consumption is moderate or aggressive. I recommend taking a quick glance at it every time you get in the car—this can help avoid rapid acceleration that wastes battery life and maintain economical driving on highways. I also use it to assist with navigation, as the system flashes to alert you to speed limit changes. Once you develop the habit, driving becomes smoother, and you won’t need to frequently check your phone. Regular maintenance of the instrument cluster is also essential, as dust buildup can blur the numbers, making it easy to misjudge and get distracted.
