As the domestic electric vehicle market becomes more and more popular, more and more consumers are considering adding electric vehicles to their next car replacement goals, in addition to the power performance, battery life and the performance of the vehicle itself , The follow-up maintenance cost after purchasing a car is often one of the homework that must be done before purchasing a car.

Hyundai automobile general agent Nanyang Industrial officially introduced the Kona Electric to the domestic market in the third quarter of this year, becoming Hyundai's first electric vehicle in Taiwan. The body size of the Kona Electric is the same as that of the Kona gasoline model, and the main difference is the power system; The domestically introduced Kona Electric is divided into two models, " EV300 " and "EV500". The former is equipped with a 39.2kWh liquid-cooled lithium battery and has a cruising range of 312 kilometers (WLTP test standard); EV500 is equipped with a 64kWh liquid-cooled battery. The cold lithium battery has a cruising range of 482 kilometers (WLTP test standard); both models use front-wheel drive settings, the AC AC charging port specification is J1772, which is common outside the Tesla camp, and the DC DC charging port specification is CCS1.

Judging from the specifications of Kona Electric, the cruising range of the BP5275-25 is actually close to that of the fuel car model, which is enough for urban commuting or occasional driving trips. Except for the different experience of charging/refueling, it is basically normal driving. Electric vehicles do not need to change their driving habits. As for the post-purchase cost of regular maintenance and maintenance of the vehicle, I believe it is the part that many prospective car owners care about. The first is the annual tax that must be paid. For the most common 1.6-liter engine fuel passenger car , the annual fixed expenditure license tax plus fuel is 11920 -ic/" title="11920 model">11920-ic/" title="11920 model">11920-ic/" title="11920 model">11920- ic/" title="11920 model">11920-ic/" title="11920 model">11920-ic/" title="11920 model">11920-ic/" title="11920 model">11920-ic/ " title="11920 model">11920-ic/" title="11920 model">11920 yuan, and the electric vehicle license-free tax concession has been extended to 2025 -ic/" title="2025 model">2025-ic/" title="2025 Model">2025-ic/" title="2025 Model">2025-ic/" title="2025 Model">2025-ic/" title="2025 Model">2025-ic/" title= "2025 model">2025-ic/" title="2025 model">2025-ic/" title="2025 model">2025-ic/" title="2025 model">At the end of 2025, plus itself no fuel consumption Therefore, the fuel fee is free, and after using the vehicle for five years, you can save about 60,000 yuan in license fuel costs.

On the other hand, since the engine oil does not need to be changed regularly like the internal combustion engine, the fixed consumables required by electric vehicles are much less than those of fuel vehicles. Taking Kona Electric as an example, only the dust filter and brake oil (parts) need to be replaced every 20,000 kilometers. The cost of salary increase is 2,980 yuan), and the system low-conductivity coolant is replaced every 60,000 kilometers (the coolant cost is 7,250 yuan). Therefore, after five years of use and about 100,000 kilometers, the cost of regular maintenance is significantly lower than that of fuel. vehicle, becoming one of the advantages of electric vehicles.

Some netizens will definitely ask: The main core of an electric car is the battery. Although the 8-year 160,000-km warranty provided by Hyundai cars can reduce the concerns of most car owners, if the battery fails in the future, it may still be a big expense. According to experience, the cost of batteries decreases year by year, the electric vehicle market continues to flourish, and battery technology will usher in breakthrough development; and the current situation, it is true that batteries account for a large proportion of the cost of electric vehicles. If the battery is unfortunately damaged or its performance Recession, replacement costs may cause a lot of blood loss in the wallet, but Hyundai Kona Electric, which emphasizes that it is "your first electric car", the general agent of Hyundai Kona Electric has introduced the battery disassembly and maintenance technology from the original Hyundai factory, which will greatly reduce the need for battery packs. Replacement expenses, we will introduce this first domestic maintenance service.

At the beginning, I would like to share a concept with you, that is, most of the batteries carried by electric vehicles adopt a modular design, that is to say, the batteries carried by an electric vehicle are usually composed of several sets of modules, and a single module is also It consists of an array of batteries connected in series; for example, most of the smart phones that are necessary for modern people use built-in lithium batteries. But if you can replace the battery alone, you can continue to maintain the life of the phone itself.

Hyundai's unique "battery disassembly and maintenance technology" is to find out the battery module with performance degradation through detection when the battery is damaged or its performance is reduced, and restore the battery to its original state through power balance or replacement of a single module. In the initial state, the best state of the electric vehicle can be maintained continuously.

After Kona Electric introduced domestic sales, the general agent Nanyang Industrial also introduced this battery disassembly and maintenance technology. This time, I had the opportunity to witness the operation of this technology; through Kona Electric's own sophisticated power supervision system , The battery operation can judge its status through various instrument lights. For example, when the vehicle is ready, the Ready light will be displayed, and the charging completed or charging will also be distinguished by different colors of lights. If the battery module is abnormal, it will also be displayed. Drivers will be alerted with a light signal.

Assuming that the battery abnormality light is on on the instrument panel, when returning to the factory for maintenance, the vehicle will be parked in the electric vehicle warranty area, and a warning sign of "high voltage danger" will be placed on the roof.

For the sake of safety, the electric vehicle needs to be cut off before maintenance. The maintenance technician will first remove the rear seat cushion. Below is the power-off puller of the battery pack, which can be powered off after unplugging.

Another set of power-off switches is located in the "motor room" in front. If the vehicle is in an accident and the fire and ambulance personnel carry out rescue, the plug here must be unplugged to cut off the power.

The article mentioned earlier that the low-conductivity coolant of the system that needs to be replaced regularly for electric vehicles looks like the auxiliary water tank of a fuel vehicle. If you look closely, you can find that the warning icon above the water tank cover is different from that of a fuel vehicle, which means that it cannot be opened by itself. It can only be opened by professional maintenance technicians, and the direction of loosening the water tank cover is also different from that of fuel vehicles, so as to avoid the danger of electrical conduction caused by careless operation.

The photo shows the actual appearance of the battery pack. In fact, the battery itself has sufficient protection capabilities. The aluminum alloy frame protects the internal battery module, and the gap between the casing is also protected by waterproof tape to prevent moisture from entering.

The Kona Electric EV500 model demonstrated this time has a total of five sets of battery modules (the demonstration model in the photo is the previous model used for education and training by the original factory), including three sets of modules under the front seat and two sets of stacked modules under the rear seat. Modules, if you look closely, you will find that each module is composed of many batteries.

Then remove the connection points and fixing screws of the battery module with a special insulating tool. After confirmation, the battery module can be moved to the next maintenance point.

Put the battery module in the explosion-proof box, and then install the detection line group. The protective box itself has an automatic cooling device. If the abnormal temperature of the battery is detected, the safety mechanism will be automatically activated.

Connect the dedicated detection line set, you can see that the outer casing says Kona Electric 15 or 19/20 cell battery module only.

Then carry out the test, you can see that the main menu displays "module balance", "discharge transmission", "module diagnosis" and other functions, among which module balance is the power balance function. After the battery is tested, the menu will display the voltage status of each battery cell. Maintenance The personnel can customize the voltage target, and the battery status can be optimized after the power balance of the system operation.

The "discharge transmission" function means that if the battery module needs to be transported back to the original factory for exchange, the power in the battery module must be discharged through this function, and it can be transported by plane when there is no power, and then exchanged. Replace with another set of battery modules.

When diagnosing the battery module, you can see information such as module type, module voltage, average cell voltage, and battery temperature displayed in the menu.

Then the screen will display the voltage status of each battery cell. It can be seen that the voltage of some batteries is 4.000V, and some are 4.011V. The voltage difference is still within a reasonable range, so this group of batteries is still in good condition.

Through this demonstration of battery disassembly and maintenance technology, you can understand Hyundai's intentions for the electric vehicle market. Then, all the exclusive locations that sell electric vehicles in Taiwan will set up the same electric vehicle warranty area, so that car owners can enjoy convenience. And the follow-up maintenance cost is approachable; for many car owners who worry about the problem of blood loss in the wallet due to battery failure in the future, the overhead cost can be greatly reduced by the method of split maintenance, which can greatly reduce the doubts of car owners. The currently introduced Kona Electric is only This is the first one. Next year, Hyundai will introduce a new generation of Ioniq 5 electric vehicles to be sold in China, allowing more consumers to experience Hyundai's brand-new electric vehicle ecology that subverts traditional thinking!
