What is the regulated speed range for electric buses?

[LeAdelyn]

Electric buses have a regulated speed range of (A0-80km/h). When entering the highway acceleration lane, drivers must promptly increase their speed to above 60 km/h to avoid affecting vehicles in the main traffic flow. Relevant information about speed limits is as follows: 1. Introduction to speed limits: Speed limits typically refer to the regulation of vehicle speeds within a certain numerical range over a specified length of road. 2. Purpose of speed limits: The primary purpose is to preemptively alert drivers to reasonably control their speed in subsequent sections of the road, prevent the dangers of speeding, and ensure driving safety. Speed limits are an indispensable and most critical aspect of road transport safety.

Last time I drove the company's electric bus on the highway, I specifically asked the traffic police about the speed limit standards. In China, electric buses have different speed limits based on vehicle type and road conditions: the maximum speed on urban roads is 50 km/h, on provincial and national highways it's 70 km/h, and on highways it's strictly capped at 100 km/h. Note that when the dashboard shows 100 km/h, the actual speed is about 95 km/h, and the onboard GPS speed detection will trigger an alarm. On rainy days, it's not recommended to exceed 60 km/h regardless of road conditions, as the heavy body makes it hard to brake. By the way, here's a little-known fact: many manufacturers set an electronic speed limit of 105 km/h from the factory, and exceeding it will force a power reduction to prevent battery overheating. Oh, and don't believe online claims like 'empty buses can reach 120 km/h'—last year's Henan-plated bus speeding accident was a bloody lesson.

When obtaining a bus driver's license, the instructor repeatedly emphasized that the speed of an electric bus must be determined by three indicators: the speed limit sign on the front of the bus indicates 89km/h as the design maximum speed, the actual dashboard speed limit sign shows 100km/h (as required by the national mandatory standard GB7258), and the road speed limit sign takes precedence. Experienced drivers in passenger transport know that when fully loaded, exceeding 80km/h causes a sharp increase in power consumption, and rising battery temperatures become even more dangerous. It is recommended to maintain a speed of around 85km/h on highways for both energy efficiency and safety. Last winter, while driving a pure electric bus on the Beijing-Tibet line in -15°C with snow, I had to keep the speed at 60km/h the entire way to barely make it to the service area for charging.

A veteran driver with five years of experience driving electric buses shares some hard truths: The advertised top speed of 120km/h for new buses is just for show—actual operation is limited to 100km/h due to mandatory monitoring systems. The most challenging part of provincial routes is downhill sections; you have to switch to energy recovery mode to keep speed under 70km/h on long descents, or the brake pads will start smoking. City buses have it worse, with GPS-enforced speed limits of 50km/h—exceed it three times, and you're off duty for retraining. A word of advice for newcomers: don’t stomp on the accelerator in traffic—the high torque of electric motors makes rear-end collisions more likely. Don’t ask how I know—my safety bonus got docked last month.
