Advantages and disadvantages of lithium-ion batteries in automotive applications

1. Lithium-ion battery has long life, light weight and small size. The power performance of lithium-ion battery electric bicycle is similar to that of lead-acid battery (simple electric bicycle). It takes 6 to 8 hours to charge and can run 30 to 45 kilometers depending on the battery capacity. As long as the lead-acid battery is used, At about 1/5 the weight, the lithium-ion battery of an electric bike is the biggest advantage of longevity. Disclaimer: Saying that lithium-ion batteries are expensive is just based on appearance. In fact, if you carefully calculate the cost of lead-acid batteries, they are almost the same as ordinary lithium-ion batteries. Now, ordinary lithium-ion batteries have two years of protection, and lead-acid batteries have one year of protection.

2. Lithium-ion batteries have non-activation characteristics. When using lithium-ion batteries, please note that if the battery is left in a dormant state for a period of time, the capacity will be lower than the normal value and the usage time will be shortened. However, the activation of lithium-ion batteries is very simple. Only through 3-5 normal charge and discharge cycles can the battery be activated to normal capacity. Due to the characteristics of lithium-ion batteries, they have almost no memory effect. Therefore, the activation process of the user's new lithium-ion battery is not a special method and equipment.

3. No memory effect. Customers are constantly worried about the memory effect of the battery when charging lead-acid batteries and nickel batteries. For example, lithium-ion batteries, we can use Panasonic. Lithium-ion batteries have no memory effect. If you still have customers who don’t know how to charge lithium-ion batteries, please check out the following.

1. The price of lithium-ion battery electric vehicles is too high. Because the current price of lithium-ion battery electric bicycles is several hundred to 1,000 yuan more expensive than lead-acid battery electric vehicles, it is difficult to gain recognition from customers in the market. Lithium-ion batteries are lightweight, environmentally friendly and will not cause environmental pollution after disposal. Once the application technology matures and market sales increase, the price of electric bicycles with lithium-ion batteries will decrease.

2. Charging the lithium-ion battery for too long will be counterproductive. The lithium-ion battery or charger will actively stop charging when charging. There is no so-called trickle of nickel charger that continues to charge for 10 hours. In other words, assuming that your lithium-ion battery is fully charged, the charge on the charger is also white. Although we cannot guarantee that the characteristics of the battery's charge and discharge maintenance circuit will never change and the quality is fully guaranteed, your battery will be at risk of long-term marginal loss. This is another reason why we are opposed to charging for long periods of time. In addition, in some electric vehicles, if the charger is not removed after charging for a period of time, the system will not only stop charging, but will also start a charge-discharge cycle. The manufacturer may have their own goals, but this is obviously not good for battery life. Therefore, when purchasing a lithium-ion battery electric vehicle, you should consult the company or dealer to do a good job in maintaining the lithium-ion battery.

3. The power of lithium-ion batteries needs to be improved. Lithium-ion batteries have much worse jitter ability than lead-acid batteries during charging and discharging. They are not useful for current high-power cars. The choice of lithium-ion batteries is also a major drawback here, resulting in Decreased durability.

4. Lithium-ion battery safety issues are highlighted. Lithium-ion battery safety needs to be improved. The risk of lithium-ion batteries catching on fire, melting, and bursting remains. A vehicle collision may cause a breakthrough gap in the positive and negative data of the battery. When the braking energy is quickly charged to the battery, the instantaneous ultra-high current will cause the battery to short-circuit, increase the temperature, and cause an explosion. The cause of the fire is collision, short circuit causing lithium ion precipitation, and contact with air will cause fire without wind.
