Battery life of 2-3 years, don't randomly change the charger, don't remove the speed limit of the controller.
In 1860, Plantey of France invented a battery with lead electrodes. The unique feature of this battery is that it can be recharged and used over and over again, so it is called a "lead-acid battery". Therefore, now the vast majority of electric vehicles are loaded with lead-acid batteries, because lead-acid batteries cost low, cost-effective. At the same time, some electric car batteries use lithium batteries.
The advantage of lead battery is that the electromotive force is more stable when discharging. The disadvantage is that it is smaller than the energy (the electric energy stored per unit weight) and strong corrosive to the environment. Lead battery is widely used because of its stable operating voltage, wide range of operating temperature and current, hundreds of cycles of charging and discharging, good storage performance (especially suitable for dry charge storage) and low cost.
Battery life is 2-3 years
Experienced users all know that the cost of battery is the biggest consumption of electric bicycles, so users are very concerned about extending the service life of the battery. The first thing to assume is that there is nothing wrong with the charger. Proper use by the user is crucial to the life of the battery. Precautions for using batteries are as follows:
1, do not randomly change the charger, do not remove the speed limit of the controller.
Chargers from various manufacturers generally have individual needs, so don't change chargers at will when you are not sure. If the mileage requirement is relatively long, and must be equipped with multiple chargers for remote charging, the charger that makes up the charge during the day uses another charger, and the original charger is used at night. Removing the speed limit from the controller, while increasing the speed of some cars, would reduce the safety of the car as well as the battery life.
2. Protect the charger.
The general instruction manual has instructions on how to protect the charger. Many users do not read the manual habit, often in addition to the problem after the thought of looking for instructions, often too late, so read the manual is very necessary. In order to reduce costs, current chargers are basically not designed for high vibration resistance, so the charger is generally not placed in the trunk and basket of the electric bicycle. In special cases, it is necessary to move, but also to put the charger with foam plastic packaging, to prevent vibration of the bump. Many charger after vibration, its internal potentiometer will drift, make the whole parameter drift, resulting in abnormal charging state. Another thing to pay attention to is to keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also may occur thermal drift and affect the charging state. This can cause damage to the battery. Therefore, it is also very important to protect the charger.
3. Charge every day.
Even if your endurance requirements are not long, a charge can be used for 2 to 3 days, but it is still recommended that you charge every day, so that the battery in a shallow cycle state, battery life will be extended. Some early users of mobile phones think that it is best to use the battery after basically finished charging, this view is wrong, lead-acid battery memory benefit is not so strong. Frequent discharge has a great impact on the battery life. Most chargers may be 97% ~ 99% charged after the indicator changes to indicate full charge. Although only undercharging 1% ~ 3% of the electricity, the impact on the endurance can be almost negligible, but also the formation of undercharging accumulation, so the battery is full of electric lamp or continue to float charging as far as possible, to restrain the battery vulcanization is also good.
4. Charge in time.
After the discharge of the pool, the vulcanization process began. At the beginning of 12 hours, there was an obvious vulcanization. Timely charging, can remove not serious vulcanization, if not timely charging, these sulfide crystals will accumulate and gradually form coarse crystals, general charger for these coarse crystals is powerless, will gradually form a decline in battery capacity, shorten the life of the battery. Therefore, in addition to charging every day, but also pay attention to, after the use of early charging, as far as possible to make the battery in full state.
5, regular deep discharge.
A deep discharge at regular intervals also helps to "activate" the battery, slightly increasing its capacity. The usual method is to discharge the battery completely at regular intervals. The full discharge method is to ride on a flat road under normal load conditions to the first undervoltage protection. Note that we put special emphasis on the first undervoltage protection. After the first undervoltage protection of the battery, the voltage will rise and return to the non-undervoltage state after a period of time. If the battery is used again at this time, it will do great harm to the battery. After complete discharge, the battery is fully charged. You'll feel an increase in battery capacity.
6. Develop some good habits to save electricity.
Use coasting whenever possible. Such as downhill, as far as possible to use the power off in advance to slow down. When approaching traffic lights, enter the taxi ahead of time to minimize braking. A friend told me that he would rather have one more bend than one brake, which makes sense.
When starting, it is best to add riding assistance, which can not only improve the starting speed, but also reduce the battery loss and life damage.
7. Pay attention to the charging environment.
The optimal ambient temperature for charging is 25℃. Now most chargers do not adapt to the environmental temperature of the automatic control system, so most chargers are designed in accordance with the environmental temperature of 25℃, so it is better to charge under 25℃ conditions. Otherwise, the problem of undercharging in winter and overcharging in summer is unavoidable. And the ambient temperature is really less at 25℃, so it is bound to have the problem of over-charging in summer and under-charging in winter. Fortunately, most homes now have indoor temperature control conditions, so when charging, it is best to arrange the battery and charger in a ventilated and temperature control environment.
In particular, when the battery enters the warm room in the cold outdoor state in the northern winter, the surface of the battery will appear frost and condensation. In order to avoid battery leakage caused by frost and condensation, you should not charge the battery until the temperature has risen to close to the room temperature and dried.
8. Take full advantage of maintenance conditions
Many e-bike dealers can provide battery repair and repair services and should take full advantage of these services. Some brands of e-bikes propose a battery overhaul. For example, regular battery maintenance can reduce battery damage. Repairs to the battery's state of charge can mitigate "battery obsolescence" failures, which dealers are equipped with the ability to repair easily. For water loss, it is better to refill at 70% battery capacity than at 40% battery capacity. Even some brands of products also put forward: to the specified time is equivalent to giving up the battery warranty period. Make consumers suffer undeserved losses. Therefore, consumers should make full use of battery maintenance conditions to extend and increase the service life of the battery
Through these methods, users can greatly extend the battery life. Some users have shorter ranges and longer battery life, and some problems are harder to spot. Therefore, article 4 of the "deep discharge" measures is also an effective way to find battery problems in time, do not wait for battery problems serious when it is difficult to deal with.
It depends on how you ride, usually riding without a person, know the love of the bike, do not start to power up, every day cycling discharge time is not more than 40 minutes, generally can ride for about 3 years. The important thing is not to let the battery run out of power, just like people working on an empty stomach will have a short life, so try to keep the battery fully charged when conditions permit. Use up the battery once a month and charge it to prevent the battery from reducing its own capacity. Finally, it is recommended to buy Panasonic batteries. I'm a slow typist. That's it. Ask me any questions.
