Electric car charger -DC charger
The low constant voltage value of trickle link is discussed, and the reference voltage is about 42.5 volts. This high value will make the battery lose water, which is easy to cause the battery to heat and deform. This low value is not conducive to fully charging the battery. This value needs to be lower than 41.5v; In the south; Colloidal batteries need to be lower than 4 1.5V, such as in South China. This main parameter is strict year-on-year and cannot be greater than the reference value.
Secondly, the peak voltage of the second link is discussed. The reference voltage is about 44.5V, which is conducive to charging quickly enough, but it is easy to make the battery lose water, and the current will not drop in the later stage of charging, resulting in the battery heating and deformation; This low value is not conducive to the rapid and sufficient charging of the battery, and is conducive to the transition to the trickle link. Although this value is not as strict as the first value, it need not be too high.
Finally, the conversion current is discussed, and the reference current is about 300 mA. This high value is beneficial to the life of the battery and is not easy to heat and deform, but it is not conducive to the rapid and full charging of the battery. This value is low (external), which is beneficial to sufficient power. However, due to long-term high-voltage charging, it is easy to make the battery lose water and make the battery heat and deform. Especially when some batteries are in doubt, good batteries will be damaged when the charging current drops below the turning current. The given reference value has a necessary range, basically allowing plus or minus 50 mA or even 100 mA, but not less than 200 mA. How many watts does electric car charger have? Brief introduction of charging method for electric vehicle
Charge for 2-3 hours after turning green. 2. The principle is to charge lightly (electrically) and frequently, and then recharge after using 50% each time. Don't charge too often, it will reduce battery life. 3. If you don't ride for a long time, you need to charge it regularly (once a month). 4. Long-term shallow discharge of the battery, deep discharge every three months, that is, the so-called first discharge and then charging, is conducive to activating long-term immobile substances in the deep part of the battery. The significance of lighting is riding until the voltage regulator battery undervoltage protection responds.
When you buy an electric car, electric car charger will follow you. Just pay attention when we charge. Well, the price in electric car charger is enough. See you next time.
