Analyze the shortcomings of lithium battery electric vehicles

1. The high price of lithium battery electric bicycles is due to the fact that the current price of lithium battery electric bicycles is generally several hundred to one thousand yuan higher than that of lead-acid battery electric bicycles. Therefore, it is difficult to get consumer recognition in the market. Lithium batteries are light and environmentally friendly, and there will be no environmental pollution after they are discarded. Once the application technology is mature and the market sales increase, the price of lithium battery electric bicycles will come down. 2. The charging time of lithium battery is too long. Lithium battery or charger will automatically stop charging after the battery is fully charged. There is no so-called trickle charge of nickel battery charger that lasts for more than 10 hours. In other words, if your lithium battery is fully charged, it is also white charged on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharging protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long charging. In addition, in some electric vehicles, after charging for a certain period of time, if the charger is not removed, the system will not only stop charging at this time, but also start a discharge-charge cycle. Perhaps the manufacturer of this approach has its own purpose, but it is clearly detrimental to the life of the battery. Therefore, after purchasing a lithium battery electric vehicle, you should consult the company or dealer to do a good job of maintaining the lithium battery. 3. The power performance of lithium batteries needs to be improved. Compared with lead-acid batteries, lithium batteries are much less resistant to fluctuations in charging and discharging. This is a major symptom that lithium batteries cannot be used effectively for current high-power vehicles, which leads to durability. decline. 4. The safety of lithium batteries is highlighted. The safety of lithium batteries still needs to be improved. The hidden dangers of fire, combustion and even explosion of lithium batteries cannot be completely eliminated at present. A collision of a vehicle may cause the positive and negative materials of the battery to break through the diaphragm, and the energy quickly recharges to the instantaneous ultra-high current when the battery is braked, etc., which will cause the battery to short-circuit, increase the temperature, and cause combustion or even explosion. The cause of the fire is collision and short circuit which lead to the precipitation of lithium ions, which will cause fire and combustion in contact with air. In addition, the electrolyte of a lithium battery is an organic electrolyte, and these substances are more likely to catch fire when in contact with air.
