Analysis of The top 7 Misunderstandings About Light EV And Lithium-ion Batteries
With the continuous highlighting of global environmental issues and the diversification of people's travel methods, new energy vehicles are gradually attracting people's attention and pursuit.However, there are still many misunderstandings about light EV and lithium batteries.1. The battery aging is too fast and cannot be processed.For traditional fuel powered vehicles, as long as the engine, transmission, and steering functions can operate normally, the vehicle can continue to operate. But for pure electric vehicles, after reaching the number of charging and discharging cycles, the performance of the battery will deteriorate, making it difficult to reach the level of normal use.However, currently many pure electric vehicle manufacturers have implemented a policy of 3-year or 5-year buyback. If the service life of the battery exceeds its limit at a certain stage, it will also be recycled and reused. 2. Electric vehicles are unsafe and prone to catching fire.Carl, Vice President of the German Fire Protection Association, believes that "the degree of combustion in electric vehicles is not more severe or frequent than in gasoline or diesel vehicles, it is just different." ADAC's testing once again proves that the risk of electric vehicle ignition is as low as that of internal combustion engine vehicles.The German Fire Protection Association wrote in its current recommendation: "Certified electric vehicles have a significant fire risk compared to vehicles with other power systems (fuel propulsion)." Overfire tests also indicate that regardless of the type of power system, vehicles of the same size and type have similar combustion performance. In case of fire, the battery can also be extinguished with water.3. Lithium-ion batteries are very expensive.It’s imperative to think about long-term costs. Although lithium-ion batteries have a higher initial purchase price than lead-acid batteries, their cost per cycle is lower due to their longer lifespan, making them the most cost-effective solution in the long run.Bepower's lithium-ion batteries have extremely low internal resistance and the most efficient technology, which means less grid energy is wasted and saves 30% (charging and CO2 emissions) compared to lead-acid batteries. In the long run, with the decline of lithium carbonate, now comparing the prices of lithium-ion batteries and lead-acid batteries, purchasing a lithium battery with the same capacity only costs 1.5 times that of a lead-acid battery. Lithium batteries are cheaper in the long run. 4. The cost of repairing and maintaining light EV is very high.Electric vehicles have lower maintenance costs, do not require regular adjustments or oil changes, and require fewer parts to be replaced and maintained. Generally speaking, electric vehicle maintenance only requires testing of the three electrical components, chassis, and lighting; For major maintenance, in addition to minor maintenance projects, replacing the air conditioning filter and replacing steering fluid, transmission oil, coolant, and brake fluid every two years or 40000 kilometers are also included. The price depends on the model, usually up to two to three hundred yuan. Of course, if it is a high-end model like Tesla, it will cost thousands of yuan, which is much cheaper than gasoline cars. 5. Lithium-ion batteries are not as stable as lead-acid batteries.Lithium-ion batteries are safer than traditional lead-acid batteries. Although the energy density is higher than that of lead-acid batteries, Bepower lithium-ion batteries have multi-level safety systems such as cells, modules, and casings, as well as a battery management system (BMS) with comprehensive protection functions. BMS protects against overload, overcharge, deep discharge, and overcurrent.6. Light EV has poor power performance.With the gradual standardization of the pure electric vehicle market, the inferior products that used to ride the dividends have been eliminated by the market. The performance of pure electric vehicles nowadays is incomparable to fuel powered models in the same price range. For example, models such as GAC Trumpchi Aion LX, BYD Tang EV, Tengshi X, and Tesla Model have achieved or even surpassed performance cars in the same price range. Even for entry-level compact pure electric vehicles priced at over 100000 yuan, their electric motor power can be comparable to some mainstream 2.0T low-power engines, and with the fast response characteristics of the electric motor, the actual driving pleasure is even better than them. 7. Lithium-ion batteries are not suitable for harsh environments.Through extensive testing, we have found that lithium-ion batteries perform better than lead-acid batteries in rough surface environments, high-usage environments, low temperatures, and most other environments where lead-acid batteries have difficulty or simply fail to perform. Depending on the application and use, lithium-ion batteries are available. Since the permissible operating and charging temperatures depend on each specific lithium battery pack, Bepower provides data sheets and user manuals specifying the exact operating conditions for each battery.
