Will the external discharge of a new energy vehicle damage the battery?

The general external discharge will not damage the battery, but it is afraid that the long-term discharge of high current (such as short circuit) will cause the battery to overheat and be damaged.

Generally speaking, external discharge will not damage the battery, but it is feared that a long discharge of a large current, such as a short circuit, will cause the battery to overheat and damage. Normal external discharge will not damage the battery.

New energy vehicles. If the battery is broken, if it is the original battery, it can naturally be claimed according to the car damage after the traffic accident, because in terms of insurance liability, it mainly refers to the protection of the "three electrics" system, so the insured needs to choose to inform the insurance company as soon as possible after the accident.

In fact, new energy vehicles also need compulsory insurance after purchase, but because the scope and amount of compulsory insurance are not very extensive, the insured also needs to purchase a commercial insurance. Under normal circumstances, car damage insurance in commercial insurance.

and third-party liability insurance.

It is necessary for the insured to purchase. And the three are risky.

It is mainly based on the premiums charged according to different compensation amounts, but most of the insured people buy a 500,000 compensation amount.

If you purchase these two types of insurance, you can take out other additional insurance. For example, excluding deductible special insurance, as long as there is this type of insurance, it means that the part of the car owner's claim can be paid by the insurance company. Of course, the specific choice also needs to be decided according to the specific situation of the individual.

This is because these two types of insurance are not compulsory to be purchased by the state.

The independence of internal audit refers to the objectivity and impartiality relative to the management of the company, precisely because it evaluates the activities of the management, and the internal audit is directly appointed by the top management of the organization or the board of directors and is also carried out under its guidance and supervision, and the communication object is the top management and the board of directors, similar to the representatives sent by the top management to inspect the work. The focus of the work inspection is on "business activities", "internal controls" and "risk management" within the organization, which places extremely high demands on technology and capabilities. At least not less than the standards of external audits, it is an unwelcome reality – at least not for the company's managers.

Because of this, internal audit is actually a relatively awkward job, although nominally it is said that audit is divided into: general audit, national audit, internal audit, but in fact, whether from the perspective of social attention or status, internal audit is far inferior to the audit of the firm.

The batteries are all externally discharged, and the internal discharge is serious, indicating that there is a problem with the battery.

Summary. Hello, new energy vehicles have an impact on the power consumption, and charging the power consumption after drying up the energy consumption will not only greatly reduce the charging efficiency, but also cause damage to the battery over time.

Hello, new energy vehicles have an impact on the power consumption, and charging the power consumption after drying up the energy consumption will not only greatly reduce the charging efficiency, but also cause damage to the battery over time.

For the question of how much power is left in the new energy pure electric vehicle to be recharged, the hydrogen cloud chain has inquired about the report of the relevant models, showing that the best charging power is in the range of 20% and 90%, and the power in this range can be charged again, which can reduce the impact of charging on the power battery and effectively extend the service life of the power battery. As we all know, the current domestic power batteries are mainly ternary lithium and lithium iron phosphate, and the ternary lithium battery is most afraid of overcharge and overdischarge, which overcharge will lead to **, and overdischarge (venting) will lead to the failure of the entire battery. Of course, in order not to let the new energy vehicle appear over-discharged, some manufacturers will set the battery power at about 15% alarm prompt, of course, at this time the vehicle is not unable to walk, it also leaves a certain driving mileage, if you still want to drive, the speed of the car will also be limited to a certain extent, even if the accelerator pedal is pressed to the end, the vehicle speed can only be maintained at about 40 kilometers per hour.

If you do this often, the charging efficiency will not only be greatly reduced, but also cause damage to the battery over time. This is the same as the impact of the fuel tank running empty, when the fuel vehicle has too little fuel, you need to refuel in time, and the long-term empty fuel tank storage will lead to the failure of the oil float (sensor) in the fuel tank (the oil float needs to be soaked in the fuel, and the fuel tank will be exposed to damage when it is in space). In terms of extending the service life of the power battery, in addition to overcharging and overdischarging, when the electric vehicle needs to be stored for a long time, the battery should be fully charged first, and then discharged to about 40%-60% before storage, and then operated again every 2 weeks or so.

In this way, it can not only avoid storage at full charge, but also avoid battery power loss, which can effectively maintain the battery activity and prolong the battery life.

There are 20 miles left.

Hello dear, this is no problem.

Try not to put the battery below 20%.

This is the best way to protect the battery.

The battery will be damaged if it loses power for a long time. If the battery is deeply discharged and the voltage is lower, the sulfuric acid and the lead plate will generate lead sulfate, and if it is not charged in time, the lead sulfate will cause the battery to vulcanize, resulting in the scrapping of the battery.

Car batteries. There is one characteristic, and that is self-discharge. Even if it is parked there motionless, the car battery will gradually discharge, and after a long time, it will become a well-known loss of electricity, and even cause irreversible damage to the battery, and the battery life will be greatly reduced.

Plus part of the electrical components of the vehicle.

It won't stop working because it stops working, so don't think it's good if the car doesn't drive for a long time. Generally speaking, the car does not turn on for half a month, although the battery is still charged, but the voltage has dropped, and it has become difficult to start. If the vehicle is parked for more than three months, the battery power is almost completely discharged.

Note that the amount of electricity consumed has a certain relationship with the manufacturing process of the battery.

It doesn't matter if the car runs out of electricity, but it's best not to do it often, because after this will make your car prone to problems and reduce the performance of the car.

The new energy vehicle battery can still be opened if a group is broken, and the Changsheng infiltration battery of the new energy electric vehicle is composed of a single cell, and the model of the battery cell is basically 18650, which is a diameter of 18mm, a height of 65mm, and a cylindrical cell. The voltage of each single cell is between to, and the minimum cannot be lower, and it may break down at any time if it is lower.

The failure of the battery usually includes excessive cell pressure difference, leakage, wiring harness contact problems, insulation faults, BMS system ridge resistance faults, temperature sensor faults, etc., and the cell pressure difference problem is the most frequently encountered.

If the battery cell pressure difference of the electric vehicle is too large, what is the performance: the cell pressure difference is too large, which will not cause the electric vehicle to be unable to drive, but will only cause the battery life of the electric vehicle to be significantly reduced, which can run about 200 kilometers normally, and the battery life will drop to 150 kilometers in a short time. The single cell of the electric vehicle adopts the mode of parallel + series connection, which has a barrel effect.

For example, if the voltage of one cell of the whole battery is and the other cells are there, then when the voltage of the problematic section drops, no matter what the voltage of the other cells is, the car will break down.

Generally, the highest cell voltage and the lowest cell voltage will be displayed on the meter of electric vehicles, and how to judge the quality of the battery by the voltage difference. The easiest way is to look at the voltage difference between the highest and lowest voltages, if the voltage difference is large, it is basically a cell damage. As shown in the figure above, the highest unit voltage, the lowest cell voltage, and the differential voltage are reached, and it is determined that there is a cell damage.

If the cell is broken, the battery needs to be dismantled and the battery cell replaced, and the battery cell generally cannot be replaced alone, only a small group of more than 100 cells.

The battery is now guaranteed for five years and 200,000 kilometers, and if there is a problem, then it must be replaced in time at the service station during the warranty period.

New energy vehicles can be discharged, and when charging, electricity can be used in the car. However, if high-power appliances such as air conditioners are used at this time, the charging power will be reduced, which will prolong the charging time and affect the charging of other vehicles. Therefore, from the perspective of resource possession, it is not recommended that users of new energy vehicles sit in the car and use electricity while charging.

For the vast majority of new energy vehicles, it is possible to use electricity in the car when charging. However, if high-power appliances such as air conditioners are used at this time, the charging power will be reduced, which will prolong the charging time and affect the charging of other vehicles. Therefore, from the perspective of resource possession, it is not recommended that users of new energy vehicles sit in the car and use electricity while charging.

In fact, when charging, sitting in the car will also have a certain adverse effect on the power battery.

The power battery of new energy vehicles belongs to the lithium-ion battery, which is a chemical battery that uses chemical reactions to achieve charging and discharging. During charging, the lithium ions inside the battery are de-intercalated from the positive electrode, and then embedded into the negative electrode through the battery separator through the electrolyte, so that the vicinity is in a lithium-rich state; The opposite is true when discharging.

When the battery is charged and discharged, it will generate heat, and the larger the current of charging and discharging, the more heat will be generated. Due to the high power of electrical appliances such as on-board air conditioners, power can only be drawn from the power battery. When charging a new energy vehicle, the internal temperature of the battery itself has gradually risen, and the battery will also undertake the discharge task, and the internal temperature rise of the battery will accelerate.

If the new energy vehicle does not unplug the charger after it is fully charged, the charger will generate heat during the process because the charger is still working. If the quality of the charger is not very good, there is a natural situation that will burn the charger, or even cause a fire safety accident. The consequences are unimaginable.

If the new energy vehicle fails to power off in time after being fully charged, the charging will continue to float the battery. Generally speaking, after being fully charged, the charger will still supply current to the battery, although the current in this part is very small, but in the long run, it will also accelerate the rapid reduction of battery life, so it is very important for new energy vehicles to be powered off or removed from charging in time after being fully charged.

There are fire safety hazards.

If the new energy steam soaker car does not unplug the charger after it is fully charged, the charger will generate heat during the process because the charger is still working. If the quality of the charger is not very good, there is a natural situation that will burn the charger, and even cause fire safety accidents. The consequences are unimaginable.

The battery is bulging, and now the battery used in new energy vehicles is basically a ternary lithium battery, this kind of battery and mobile phone battery is a large category, which belongs to lithium batteries, and the phenomenon of overcharging and bulging mobile phone batteries is often seen in the era of feature machines. Then this will also happen on new energy vehicles. Especially in hot weather, it is important to avoid overcharging.

Although the amount of power required to increase power consumption is not very large, the power lost in the long run is also quite a lot if the charger is not pulled out for a long time, so it is necessary to pay attention to the charging time when charging the new energy vehicle, charge it reasonably, and avoid excessive energy waste.
