Error 1: Charge the battery immediately when the electric car stops. The correct approach is to stop the electric car for half an hour or more, and then charge it. The electric vehicle is in a riding state, the battery itself will fever, plus the weather hot, the temperature of the battery can even reach 70 ¡ã C, at this time, the battery is charged to exacerbate the downtime, reduce the battery life, intensify Battery drum risk.

Error 2: Charging the battery in the case of the sun direct in the sun. The correct approach is: Try to charge the battery in the cool place, or choose to charge the electric car during the evening. The battery will also heat during the charging process, if charging in the case of direct sunlight, it can cause the battery to lose water, causing damage to the battery.

Error 3: Charging time is more than 10 hours, even charging. The correct approach is: whether there is no light charging time without the charger within 10 hours. Many electric car users are convenient for the map, often charging overnight, and the charging time is often more than 12 hours, and sometimes forgets that the power charging time is more than 20 hours, this will inevitably cause great damage.

Multiple times, it is easy to cause the battery to be drummed because of the charge. Error 4: Electric vehicle charger does not do special charger. The correct approach is: charger special car, if it is broken, it is timely to the car shop or repair shop by professional examination, with a new charger.

There are two or more electric cars, and many electric vehicles are different brands, different models, and battery models are also different. The charger is naturally different. It cannot be universal.

The correct practice is a special charger, but Some electric car users are in the process of use, often mixed with, even take 60V charger charge 48V battery, take 20AH charger charge 12AH battery, charging voltage and current do not match, will cause damage to the battery. Error 5: Charging the battery using a miscellaneous charger. The correct approach is: to a professional electric vehicle or repair shop to buy a regular brand charger.

At present, the electric motor market is full of inferior chargers. Many consumers do not pay attention to the quality of the charger, which is cheap, think that the charger can charge the battery to the battery. The electronic components of the miscellaneous charger are basically adopted by inferior materials.

It is easy to damage. The frequent problem is that the battery is fully charged without turning the lamp, and the charging current cannot be adjusted according to the battery, resulting in a large number of batteries, after multiple times. Battery will be drumming.

Electric vehicle charger, if it is not normal to use, it is recommended to replace a high-quality brand charger to replace a professional electric vehicle after-sales service store to ensure the quality of charging, delay battery life. Error 6: Charging battery using fast charging station. Correct approach: Check the power before going out to ensure that the electric vehicle has normal power to meet the travel needs, if the battery is insufficient, charge it before going out.

Now, many cities have a large number of fast charging stations distribution, on the one hand, it brings convenience to electric vehicle users, on the other hand, the fast charging station large current charging causes serious water to be depressed, long-term use is an important reason for the driving drum. There is an electric car user to reflect, just changed the battery without use for half a year, and finally understands the results of multiple use of fast charging stations. Error 7: Electric vehicle charger carries with the car.

Correct approach: The charger should be stored in a fixed place. If you have more charger. Some electric car users, for the convenience of charging, I like to bring the charger in the car.

In fact, the electronic components on the electric vehicle charger motherboard are welded, some large electronic components, bumps, can cause demondering, resulting in contact Poor, the current is unstable and the protection function is invalid during charging, resulting in battery damage. Summer these most hurt the electric motor battery charging method, it is easy to get the battery, don't recruit it! In addition, we must know how to prevent battery explosions! Three of the battery explosion: And when charging, the electrolyte temperature has risen sharply, and the water will evaporate the water. At this time, if the vent hole cover is blocked, since the gas is too late to overflow, the pressure inside the battery will rise high, first causing the battery slot to deform, when the internal pressure reaches a certain pressure, the bore is bonded or otherwise The weak is burst, this is a physical process.

When the internal pressure of the battery is higher than 0.25 MPa, the battery is burst, and the burst position is located at the angle of the trough hot air bonding or stress concentration. 2.

Hydrogen is meticulous, and the explosive limit of the battery explosion H2 and O2 mixed gas formed by H2 is H2 4% -96%, H2 and air mixed gas of H2 and air is a 4% -74 of the mixed gas volume. %. If 80% of the charge amount is used in electrolytic water, the H2 content inside the battery is greater than the explosion range.

When the amount of hydrogen in the battery or the amount of hydrogen is accumulated to the explosion limit, it will form an explosion, which is an explosion. Chemical reaction. Studies have found that the explosion of the battery belongs to the branched explosion reaction.

There are too many such explosions that occur in the case of overcharge, if there is a spots in the internal column, wearing welding, etc. A qualified battery does not have a self-heating explosion in normal use conditions. When the battery charging voltage gasoline car is higher than 14.

4V, the diesel car is higher than 28.8V, and the explosion may occur under the conditions of the simultaneous existence. Through the vehicle inspection of the battery explosion, it is found that most of the voltage regulators have defects, and the battery is in a serious overcharge.

3. Due to the blockage of the battery exhaust hole, the battery is burst, burst causing the battery vibration, and the pole pillar is not in prison, thereby forming an explosion.
