Can I add a battery if my electric bike rides slowly?
Recently, an electric car user asked such a question: The e-bikes he just branded are riding slowly. Can I add a battery to make the speed faster? For this question, my answer is that you can not add batteries, there are four main reasons.
1. The size of the battery box is limited, new batteries cannot be added
Everyone knows that the batteries are carefully designed before leaving the factory, including the size of the battery box. Only when the battery is made will there be no leakage due to shaking. Take the 48V electric bicycle as an example, it is composed of 4 small 12V batteries, and the battery box has and can only accommodate 4 small batteries, it is impossible to add new batteries.
2. The new national standard for electric vehicles restricts that electric bicycles with new batteries added without permission
In the provisions of the new national standard, the battery of the electric bicycle cannot exceed 48V. If the user wants to add a new battery, it clearly does not meet the new national standard. Such an electric vehicle will be classified as a non-standard vehicle. Even if the user has already obtained a license, such an electric vehicle still cannot enjoy the right of way, which is a violation modification. Many people may want to say, can we classify this kind of car as electric motorcycle? The answer is no. Therefore, from this point of view, electric bicycles can not add batteries.
Third, the failure rate of electric bicycles with privately added batteries is higher
In theory, electric bicycles are slow to ride, and adding a battery can make the speed faster. However, from a practical point of view, the addition of a battery is likely to burn out the motor or controller, making the electric bicycle failure rate higher. And this means that if you want to add batteries, you must also replace the motor and controller, and match. From this point of view, the disadvantages of adding a battery outweigh the benefits, and the cost is too high, so it is impossible to add a battery.
4. The safety risk of electric bicycles with privately added batteries is greater
It is mainly reflected in two aspects. First, the electric bicycles with privately added batteries have worse stability and accompanying risks. Secondly, electric bicycles with privately added batteries are not within the scope of the manufacturer's warranty. If there is a problem with the electric vehicle, you can only solve it by yourself. Therefore, electric bicycles are slow to ride, and it is not feasible to add a battery.
In short, from these four points of view, even if the speed of the electric bicycle is slow, the battery cannot be added. In fact, users don't need to increase the speed by adding batteries. According to the current market situation, electric motorcycles and electric motorcycles can be put on the road.
