1, don't change the charger casually, and don't dismantle the controller for speed limit.
Chargers from various manufacturers generally have personalized requirements, so don't change chargers at will under uncertain circumstances. If the mileage is required to be long, it is necessary to equip multiple chargers for charging in different places, so the charger for recharging during the day is supplemented by another charger, and the original charger is used at night. Canceling the speed limit of the controller can improve the speed of some cars, which will not only reduce the safety of cars, but also reduce the service life of batteries.
2. Protect the charger.
There are instructions on protecting the charger in the general instruction manual. Many users don't have the habit of reading the instructions, and often think of looking for the instructions after the problems appear, which is often too late, so it is very necessary to read the instructions first. In order to reduce the cost, the current chargers are basically not designed with high vibration resistance, so don't put the chargers in the trunk and basket of electric bicycles. It must be moved under special circumstances, and the charger should be packed with foam plastic to prevent vibration and bump. After many chargers vibrate, the internal potentiometer will drift, making the whole parameter drift, resulting in abnormal charging state. In addition, keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also affect the charging state due to thermal drift. This will damage the battery. So it is also important to protect the charger.
3. charge every day.
Even if your continuous running ability is not long, you can use it for 2 to 3 days on a single charge, but it is recommended that you charge it every day, so that the battery will be in a shallow cycle and its life will be extended. Some early mobile phone users think that it is best to recharge the battery after it is basically used up. This view is wrong. The memory benefit of lead-acid batteries is not so strong. Frequent discharge has a great influence on battery life. Most chargers may charge 97% ~ 99% of the battery after the indicator light becomes full. Although only 1% ~ 3% of the battery is under-charged, the impact on the ability to continue driving is almost negligible, but it will also form under-charged accumulation, so it is also beneficial to continue floating charging as much as possible after fully charging the battery with the electric variable lamp.
4. Charge in time.
After the battery was discharged, the vulcanization process began, and obvious vulcanization occurred in 12 hours. If the battery is charged in time, trace sulfide can be removed. If not charged in time, these sulfide crystals will accumulate and gradually form coarse crystals. General chargers are powerless to these coarse crystals, which will gradually reduce the battery capacity and shorten the service life of the battery. Therefore, in addition to charging every day, you should also pay attention to charging as soon as possible after use, and make the battery fully charged as much as possible.
5, regular deep row.
Periodic deep discharge of the battery is also beneficial to activate the battery, which can slightly improve the battery capacity. The general method is to discharge the battery completely at regular intervals. The method of complete discharge is to ride to the first undervoltage protection under normal load on flat road. Note that we particularly emphasize the first undervoltage protection. After the first undervoltage protection, the battery voltage will rise after a period of time and return to the non-undervoltage state. At this time, if the battery is reused, it will cause great damage to the battery. After fully discharging, fully charge the battery. You will feel that the battery capacity has increased.
6. Develop some good habits of saving electricity.
Use taxiing whenever possible. When going downhill, power off and slow down as early as possible. Enter the taxi in advance when you are about to meet the traffic lights, and try to reduce the brakes. A friend told me that he would rather turn the bay one more time than step on the brakes one less time, which makes sense.
It is best to add riding assistance when starting, which can not only improve the starting speed, but also reduce the power loss and life loss of the battery.
7. Pay attention to the charging environment.
The optimum ambient temperature for charging is 25℃. At present, most chargers have no automatic control system to adapt to the ambient temperature, so most chargers are designed according to the ambient temperature of 25℃, so charging at 25℃ is better. Otherwise, it is inevitable that there will be problems of insufficient charging in winter and excessive charging in summer. However, when the ambient temperature is really lower than 25℃, there will inevitably be problems of overcharging in summer and undercharging in winter. Fortunately, most families now have indoor temperature regulation conditions, so it is best to arrange the battery and charger in a ventilated temperature regulation environment when charging.
In particular, in the northern winter outdoor low temperature state, the battery enters the greenhouse, and the surface will be frosted and dewed. In order to avoid the leakage of the battery caused by frost and dew, the battery should be recharged after the temperature of the battery is raised to close to the indoor temperature and dried.
