What kind of better electric lithium battery and lead acid battery

Source: 2020 - 03 - 25 clicks: when time generally believe that the electric car with the lead-acid batteries is better than the lithium battery, mainly because of their high cost performance. If say endurance, and other conditions are exactly the same, the capacity of the battery is the same, so the lithium battery. Lithium-ion batteries on the volume and weight of energy more than three times the lead-acid battery. Lithium battery volume smaller, lighter weight, long cycle life. Due to the lithium battery is lighter, the electric car is lighter, of course run longer. Lead-acid batteries of electric cars in the market, however, is still higher than that of lithium battery, lead acid battery and lithium battery is good, can't simply use the quality of the battery in order to quality, there are advantages and disadvantages, to meet the needs of different groups, consumer should choose according to their needs. Lead-acid battery in general, a set of lead-acid as long as several hundred yuan, a set of lithium batteries, more than 1000 pieces of about 2000 pieces. Lead-acid battery overload capacity and impact resistant capability is strong, the electric vehicle running resistance, change at any time, a sudden stop, even when the battery current is changed a lot. Lead-acid battery can also be seen as overloading of a car, two or three hundred amperes of current in a few seconds. In the process of charging, lithium battery needs to control the charging voltage and charging current, accurate measuring the battery voltage. According to the lithium battery voltage, charging process is divided into four stages. The first stage is charging. With 0. 1 c of small current charging of lithium battery. When the battery voltage & ge; 2. 5 v, the battery into the next phase. The second phase of constant current charge. Use 1 c constant current for quick charge lithium battery. When a battery voltage & ge; 4. 2 v, into the next phase. The third stage is the constant voltage charging. Gradually decrease the charging current, ensure the battery voltage constant = 4. 2v。 When the charging current & le; 0. 1 c, into the next phase. The fourth stage is trickle charging. Constant voltage charging is completed, batteries fully charged. In order to keep the battery voltage, battery can be used to 0. 1 ℃ or lower charging current. When not plug in, leds on the circuit board is not bright; Power supply is connected to the circuit boards, the green LED lights to continue on. At this point, the circuit board is waiting for the placement of lithium battery. Start charging in lithium batteries, LED into orange. When the lithium battery reaches full charge state, will stop charging, the LED into orange. When lithium batteries, battery, LED turn green. When charging, charging status percentage. LED lights: continue to green: wait for the battery; Continue to yellow: charge; Continue to orange: the battery is full or full of 6 hours; Flashing orange: warning information ( Output short circuit, positive and negative inversion, abnormal temperature) 。
