Lithium batteries are good. According to query and off-grid display:
1. The energy density of water batteries is relatively low, while lithium batteries have a higher energy density and can provide electrical power for a longer period of time.
2. Hydroelectric batteries have strong economic advantages, but their lifespan is short, between 2 and 5 years. Lithium batteries have a longer lifespan, between 4 and 5 years.
Is the battery of an electric vehicle better, a lead acid battery or a lithium battery?
Of course, the lithium battery is better, but when When purchasing an electric vehicle, you also need to consider economic issues. Lithium batteries are more expensive than lead-acid batteries, with the same voltage and capacity about three times more expensive.
Battery comparisonsies for battery cars are as follows:
Lithium-lead acid battery
1 Rechargeable battery
2. Use life (500 times - 400 times)
3. Specific energy (150W·h/kg - 40W·h/kg)
4. 6~8h)
5. Discharge energy efficiency (discharge efficiency of lithium battery can be above 90% - discharge efficiency of lead-acid battery is above 80%)
6. (compared to High - lower)
7. Volume (small volume, the volume of lithium-ion battery is 2/3 of the volume of lead-acid battery - large volume)
8. Weight (weight It is only 1/3 ~ 1/4 of the lead-acid battery - heavy)
9. Batteries of the same specifications, because lithium batteries are composed of several cells. , although the efficiency of a single discharge is high, however, the overall efficiency decreases, so the mileage of the two batteries is approximately the same)
10. Pollution during production and use (there is pollution in production-lead). -acid batteries contain a large amount of lead and the acid, if not handled properly after disposal, will pollute the environment).
11. Discharge (susceptible to deep discharge and short circuit damage - vulnerable to deep discharge damage)
12. Charging and maintenance (complex and high maintenance costs - simple and low maintenance cost). )
Lithium battery.
For electric vehicle users, many people prefer lithium batteries. In terms of quality, lead acid batteries are larger, heavier and non-detachable. Compared to only a few lithium batteries. a kilogram is very bulky. Lithium batteries are smaller, very portable and removable, and have better operabilitythan lead acid batteries. Especially for women, lithium batteries are more acceptable because even women can pick them up easily, which is very convenient.
Precautions for using electric vehicle batteries
Try not to carry people or heavy objects when driving an electric vehicle to avoid overcharging the battery.
If the charger does not have temperature compensation function, you should charge at room temperature (25°C) as much as possible (indoors, especially when used in winter) . Once the charger turns green, continue charging for 2-3 hours, then turn off the power.
After the electric vehicle battery is exhausted (the undervoltage indicator light is on), the power must be turned off and driven manually. Do not use “recovery voltage” for operation.
