How does BAIC Magic Speed h2e keep calling the police after replacing a new battery?

The reason why Beiqi Magic Speed h2e kept giving an alarm after replacing the new battery is because the battery is replaced when the power is cut off, and the driving data in the driving computer will be cleared when the power is cut off, so the alarm phenomenon appears after the replacement, because some data of the system have been restored to the factory settings, so the driving computer needs to correct the data.

Battery is a kind of battery, also called battery. Its working principle is to convert chemical energy into electrical energy. The storage battery usually refers to lead-acid storage battery, which is mainly made of lead and its oxides as electrodes and sulfuric acid solution as electrolyte.

Battery refers to the battery that can continue to be used after discharge and charging, including lead battery, nickel-iron battery and nickel-cadmium battery. The anode of lead storage battery is lead dioxide, the cathode is lead and the electrolyte is dilute sulfuric acid solution.

principle of operation

A lead plate filled with sponge lead is used as a negative electrode, a lead plate filled with lead dioxide is used as a positive electrode, and 22-28% dilute sulfuric acid is used as an electrolyte. Electrical energy is converted into chemical energy when charging, and chemical energy is converted into electrical energy when discharging.

When the battery is discharged, metal lead is the negative electrode, which is oxidized into lead sulfate. Lead dioxide is the positive electrode, which is reduced to lead sulfate by reduction reaction. When the battery is charged with direct current, lead and lead dioxide are generated at two poles respectively.
