Fully Electric Vehicles, Only One Grid Left With A Gas Pedal, What Happened?

Gold Light Power Manufacture Company | Updated: Dec 28, 2018

Fully electric vehicles, only one grid left with a gas pedal, what happened?


Recently, many friends have consulted about the battery problem through the background. This is also the situation that many electric vehicle users may have encountered. It is obvious that the battery is fully charged. When the electric vehicle accelerates, it directly drops two grids and goes to the maintenance point to detect the battery. And no problems found, then what is the reason?

Today, Xiaobian will explain to you three main reasons for this situation.

01 battery process

In the early days of the new environmental protection policy, that is, in 2014, the state called for the implementation of the cadmium-free internalization process in the battery industry. Cadmium in lead-acid batteries can enhance the conductivity of the battery, reduce the internal resistance of the battery, improve the discharge voltage of the battery, and withstand high and low temperature, good charge and discharge performance. After the battery process is selected without cadmium + internalization, the battery performance is affected. The most obvious point is that the initial voltage of the battery is low, that is, the battery will be fully charged, and the acceleration will easily occur when two cells are discharged.

But you don't have to worry, the cadmium-free + internalization process is in line with the sustainable development of the battery. After achieving sufficient circulation, the battery performance will gradually increase and the service life will increase.

02 battery self-discharge

Some users do not ride immediately after fully charging the electric car, but leave the electric car for several days. However, the electric vehicle battery itself has a self-discharge condition, so the longer the standing time is, the larger the power loss is, and the faster the battery voltage drops. When the user rides again, it is easy to see an acceleration of two grids.

The electric car should be fully charged before it is idle. After 3-5 days, charge once. The battery cannot be fully charged or overcharged, and it cannot be undercharged or charged.

03 line damp

These days, it is rainy or rainy, and it is not ruled out that the battery line is damp. If the line is damp, the electric vehicle resistance will increase, and the electric vehicle battery voltage will drop, which will cause the electric vehicle to accelerate the two grids. When doing battery testing, it needs to be dried.

Try not to ride an electric car on rain or snow, because it is not safe, can't run, and the electric car is losing.

Finally, I would like to add to you that if you find a problem when testing the battery, it is likely that one of the small batteries is broken, causing the electric car to lose two grids as soon as it accelerates. Because one of the small batteries is broken, it will lead to voltage instability, which will lead to accelerated power failure.

In short, if the battery test is normal, the electric vehicle will lose two grids when it accelerates. Generally speaking, it is a normal phenomenon, and there is no need to worry too much. The user can eliminate the above three reasons one by one. However, the battery wants to run far and use it for a long time, but it is still inseparable from the good maintenance.
