What is the reason for a new electric bike experiencing voltage drop when accelerating?
2 Answers
The reason for a new electric bike experiencing voltage drop when accelerating is: battery moisture. Battery voltage drop is a concern for many people. Previously, electric bike batteries were made of cadmium-containing lead-acid batteries, where cadmium not only enhanced conductivity but also reduced internal resistance and extended battery life. With the introduction of environmental policies, current electric bike batteries are environmentally friendly and must be cadmium-free. The absence of cadmium affects battery performance. During initialization, the battery voltage becomes very low, leading to power loss, which is an inherent issue with the battery material itself.
I've been driving electric vehicles for several years, and experiencing false battery levels during acceleration is quite common. The possible reasons could be that the new car's battery hasn't been fully activated yet, requiring several deep charge and discharge cycles to break it in; or insufficient charging, mismatched charger, showing 100% when not fully charged; a faulty controller consuming too much power during acceleration, causing voltage to drop too quickly; quality issues with the battery itself, such as defects in new batteries or signs of aging; poor contact in the wiring leading to unstable current; or significant temperature effects, as batteries tend to overheat and performance drops in hot weather. Check your charging situation and try slow charging a few more times. If that doesn't work, take it to a professional shop for inspection. Safety first—don't risk driving it if there's any doubt.
