There are 350 million electric two wheeled vehicle owners nationwide. Therefore, although people have different perceptions of electric two wheeled vehicles, the common consensus is that the batteries of electric vehicles should be durable and cannot be replaced frequently. So, as an EV owner, do you know how often it is best to charge an EV? How to charge without damaging the battery? Here comes the answer!
How often is it best to charge the battery? This mainly depends on your battery capacity. At present, there are six mainstream battery capacities of electric two wheeled vehicles: 48V12ah, 48V20ah, 60V20ah, 60V32ah, 72V20ah and 72V32ah. The optimal charging and discharging depth of these batteries are different.
In general, the larger the battery capacity is, the greater its discharge depth DOD will be. The battery is most afraid of deep charge and deep discharge, and the ideal is shallow discharge and shallow charge. How much depth of charge and discharge (DoD) is the best?
There are two mainstream batteries for electric two wheeled vehicles, one is lead-acid battery, the other is lithium battery!
The lead-acid battery has a low energy density due to its self discharge characteristics, and its own cycle times are only about 500 times. Therefore, its optimal DOD discharge depth is 30% - 50%, which means that it needs to be charged if it is damaged. Without the SOC percentage accurate power display, generally speaking, if the dashboard is powered down first, you need to recharge it!
Compared with lead-acid batteries, lithium batteries have better charging and discharging capacity. First of all, their energy density is high, and their self discharging characteristics are not obvious. Therefore, the best charging and discharging depth of lithium batteries is 50-70%, that is, when the last two grids on your dashboard are left, you can find charging posts to charge!
Of course, the shallower the charge and discharge is, the more favorable the battery is. However, considering the actual user experience, it is unlikely to charge every day. Generally speaking, within 10 kilometers of commuting, 48V12ah new lead-acid batteries are charged every two days, 48V20ah, 60V20ah are charged every three days, 60V32ah, 72V20ah, 72V32ah are charged every five days. If it is a lithium battery, it can be postponed for 1-2 days!
How to charge an electric vehicle without damaging the battery?
Do not use an unmatched charger for electric vehicle charging, do not always charge with high power and fast charging, do not charge in high or low temperature environment, and do not charge for a long time. As long as these conditions are avoided, the batteries are basically very durable! Everybody, what do you think about this? Welcome to your message!
