1. Regular inspections

First, check the battery pack and clean the level of the battery pack cover and column to avoid dust and other debris. If it is found to be covered with debris or contaminants during the inspection, the compressed air method should be used to improve the cleanliness of the surface. Ensure the integrity of the battery pack shell and avoid deformation, cracking and other problems.

At the same time, the tightness of the tray and battery cover should also be strengthened. Only by strengthening the connection between the battery and the body can the stability of the battery be strengthened.

Secondly, it is necessary to detect the connection status of the battery, and the pole connection should be safe and stable to avoid corrosion and other problems. In addition, it is necessary to ensure that the connection point of the single battery is in stable contact with the temperature guide zone and other components of the battery pack to avoid deformation and loosening. When charging, the contact between the socket and the plug must be safe and cannot fall off.

Finally, vulnerabilities should be detected. Generally speaking, in order to ensure the stability of the current, the voltage of the lithium electronic battery pack will be stable at 300 volts, so the battery must meet the insulation requirements. At the same time, stick to routine maintenance, because if the battery is replaced and recharged frequently, its use time will be shortened and the failure rate will increase.

Therefore, the power battery should be repaired by a professional maintenance organization. Adhere to routine maintenance and testing, develop a management plan, and upgrade and repair according to the actual application of the battery. The main content is to detect voltage, battery box connector, etc.

And record the inspection and maintenance situation in time to avoid frequent maintenance and replacement, so as to reduce the maintenance cost.

2. Avoid emergency acceleration

When the new energy vehicle starts to carry people, if the power battery is used for emergency acceleration, due to a large amount of discharge, the power battery will have problems such as lead sulfate crystallization, which will affect the physical properties of the power battery. In addition, if the speed of the vehicle drops suddenly, the driver must first consider the problem of power battery failure, so it is necessary to develop correct driving habits and avoid emergency acceleration.

3. Protect the charger

In order to improve the maintenance effect of power batteries, we must pay more attention to charging. It is necessary to ensure the safety of the charger, because the chargers on the general market lack high shock resistance, so there will be many problems during the maintenance process. If the potentiometer in the charger is displaced under strong vibration, it will affect the charging effect.

Therefore, if you want to protect the power battery, you have to protect the charger.

Fourth, reduce manufacturing costs

The research and development of new energy power batteries in China is relatively late, so the core technology of the enterprise mainly comes from developed countries, especially the production of key components. According to the analysis of China's actual development, China has made certain achievements in the field of independent research and development of parts. Although there is still room for development compared with developed countries, it is necessary to pay attention to the quality and function of parts.

However, we have the best advantages, so in the process of increasing the scale of purchase, we must also ensure the function of the power battery, prolong the use time, reduce the follow-up maintenance and repair costs, stimulate people's enthusiasm for purchasing, and increase the company's economic profits.

Power battery module.

Battery cell: The smallest unit that constitutes a power battery module. It is generally composed of a positive electrode, a negative electrode, an electrolyte and an outer shell. It can realize the direct conversion between electrical energy and chemical energy;

Battery module: the combination of a group of battery cells connected in parallel, and the rated voltage of this combination is equal to the rated voltage of the battery cell, and is the smallest grouping of battery cells connected in the physical structure and circuit, and can be replaced as a unit;

Module: A combination composed of multiple battery modules or single cells connected in series.

The C30DB project uses a lithium-ion power battery system, which is a rechargeable battery, which mainly relies on lithium ions to move between the positive and negative electrodes to work. When charging, lithium ions are de-intercalated from the positive electrode and embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; The opposite is true when discharging. Lithium-ion batteries can be divided into lithium cobalt oxide batteries, lithium manganese oxide batteries, lithium iron phosphate batteries and three-element batteries according to the different cathode materials.

Regular check-ups, checking the battery connection status to avoid corrosion, checking the emergency acceleration function, protecting the charger and battery, changing the oil and filter cartridges, this is how to maintain it.

When charging, you must grasp the appropriate time, do not charge after all the electricity is consumed, park in a room temperature environment when parking, do not park in the cold outdoors, replace the battery in time, and control the charging time.

When charging, you should choose the right time, the time should be controlled in about 4 hours, not too long and not too short, pay attention to safety when charging, and usually pay attention to the problem of keeping warm.

The new energy power battery must be used with it, try not to use it until there is no power to recharge, the battery is used excessively, which has a great impact on the battery life, so try to rush frequently.

New energy vehicles should not be in a state of power loss when they are stored. Batteries stored in a state of power loss are prone to sulfation, and lead sulfate crystals adhere to the plates.

Carry out repairs on time, maintain on time, go to the 4S shop for inspection, pay attention to the charging method, and pay attention to the temperature of the car when charging.

1. Appearance: First of all, like fuel vehicles, first carry out visual inspection, including whether the paint, lights, wipers and other parts are aging and damaged, and whether the function is intact. If you need to clean the body, you can use a soft cloth soaked in a mild neutral car wash to wipe it, and the strength should be moderate, otherwise it is easy to damage the paint surface.

Tires: tires are in direct contact with the ground every day, the probability of damage is higher than other components, and it is necessary to check the tire pressure, four-wheel balance and whether there are cracks or wounds on the tread during maintenance.

Chassis: As the closest component to the road surface, the chassis is inevitably scratched during driving, and it is necessary to conduct a comprehensive inspection during maintenance, including whether the transmission parts and suspension parts are loose or damaged, and whether the chassis is corroded.

4. Cabin: The cabin inspection must be carried out by professionals, and the protection work must be done before opening the cabin, and the wiring harness in the cabin should be checked for aging and virtual connection during maintenance. Remember, due to the particularity of new energy vehicles, the interior of the cabin cannot be cleaned with water.

Battery: As the power of new energy vehicles, the battery is one of the most important components, and it is necessary to regularly go to the repair shop for inspection and maintenance. Improper maintenance or daily use can cause battery wear and tear, and replacing the battery is a significant expense.

6. Antifreeze: Different from fuel vehicles, electric vehicle antifreeze is used to cool the motor, which needs to be replaced regularly according to the time specified by the manufacturer (the general replacement cycle is 2 years or 40,000 kilometers). In addition, gear oil, also known as transmission oil, is also the oil that needs to be changed more frequently in electric vehicles.

7, fuel vehicle maintenance will use professional diagnostic equipment, new energy vehicles are the same, when there is an abnormality, will activate an error, sent to the vehicle controller, the use of Langren H6 car fault diagnosis instrument can read the fault code, clear the fault code, read the data stream, etc., H6 can not only be the fuel vehicle fault diagnosis, but also the new energy vehicle fault detection, battery system detection, motor system detection, etc., but also has headlight adjustment, airbag repair, tire pressure reset and other special functions, Meet the multi-faceted maintenance needs of new energy vehicles.

However, there are some differences between the driving methods of electric vehicles and traditional vehicles, but they still need to be maintained on a daily basis. The biggest difference between the two maintenance is that traditional cars are mainly aimed at the maintenance of the engine system, which requires regular replacement of oil and engine filters; Electric vehicles, on the other hand, are mainly used for daily maintenance of battery packs and electric motors.

The battery pack and motor of a pure electric vehicle replace the engine of a traditional car to drive the car, and the gearbox is slightly different from the gearbox of a traditional car, but the chassis and electrical parts are basically the same as those of an ordinary car.

In order to ensure that the vehicle is kept in top condition, BEVs need to be maintained regularly like conventional cars, such as changing the transmission oil and cabin air conditioning filter every year or 20,000 kilometers; change antifreeze and brake fluid every two years or 40,000 kilometers; Check the chassis, lights, tires and other conventional parts for each maintenance.

Since electric vehicles are driven by motors, electric vehicles do not need conventional maintenance such as oil, three filters, belts, etc., and only need to carry out some routine inspections on the drive battery pack and motor, and keep them clean, which shows that the maintenance of electric vehicles is indeed much less troublesome than traditional cars.

The inspection of the three-electric system is the focus of the maintenance of electric vehicles, which requires regular visits to the 4S store to plug in the computer and go through the parameters, but its importance is much higher than the conventional visual inspection. In addition to general vehicle maintenance items, such as charging system, power battery pack, system inspection, drive motor inspection, and electronic control system inspection, are all very important. It is also necessary to upgrade the motor controller, body circuit and the software system of the whole car.

In addition, the antifreeze of new energy vehicles is different from ordinary cars, it is mainly used for the cooling of motors, and this antifreeze needs to be replaced every two years or after driving 40,000 kilometers according to the specific model. In the daily maintenance, the appearance of the vehicle is the main thing, and the car is washed regularly to ensure that the paint surface is clean, and the charging time of the vehicle is correctly grasped in terms of charging, so as to avoid power loss and overcharging. The last point is to avoid high-current discharge when using, as high-current discharge of electric vehicles can easily lead to electrode crystallization, thereby damaging the physical properties of the battery plates and reducing the life of use.

New energy vehicles, like traditional cars, also need maintenance, but the maintenance items and maintenance costs are different! Fuel vehicles are mainly for the engine system, gearbox transmission system maintenance, need to regularly replace oil, filter, air filter, steam filter, etc., especially oil and filter is the most common and frequent maintenance of the project, the accumulation of a lot, the cost will come out!

New energy vehicles rely on batteries to provide energy, motors to drive, naturally omitting oil, three filters, belts and other routine maintenance items, only need to maintain the battery pack and motor, keep them clean. Therefore, the maintenance of new energy vehicles is simpler and more trouble-free than fuel vehicles! The following is about the daily maintenance of new energy vehicles, and mainly pure electric vehicles, the maintenance cycle is generally one year or 20,000 kilometers

The core components of a pure electric vehicle are the battery, motor and power system, and the main maintenance projects are also carried out around these three parts. This is followed by the maintenance of braking systems, chassis inspections, lighting inspections, tire inspections and other items. The first task is the component that needs frequent maintenance, of course, is the power battery pack, and the vital importance of the power battery pack to new energy vehicles is also self-evident.

Car owners of new energy vehicles need to regularly maintain the condition of the power battery pack to prevent power loss of the power battery pack, and also need to pay attention to eliminating potential safety hazards.

Then there is the motor, which is the key component to drive the driving of new energy vehicles. Like traditional fuel vehicles, the motors of new energy vehicles also need to be replaced with coolant on a regular basis; Then there's circuit detection. Compared with the circuit of a fuel vehicle, the circuit of a new energy vehicle is much more complex, and at the same time the voltage must be much higher.

For our safety, we need to regularly maintain whether the joints are loose, whether the wiring is aging, and so on. Finally, in addition to the testing of the three-electric system of new energy vehicles, we also need to test the brake pads, tires and wipers and other commonly used wearing parts of new energy vehicles. For example, to detect whether the tire pressure is normal, whether the brake pads are aging, etc., must not be negligent.
