The Proper Use of Lead Battery for Electric Bicycle

update:2017/5/24, view:

Battery / battery is the power source of electric bicycles, but also a consumable, and the price is high, so the battery to maintain a good working condition, to extend its service life, both from the environmental or economic point of view, there are great Practical value. The following is some of the battery maintenance methods (the following is from the perspective of ordinary electric car users, the maintenance and the quality of the battery itself, we do not tell here, the reader can refer to our later explanation or other information):

1, the new purchase of the electric car should be fully charged and then use. Because many electric cars in the store has been shelved for a few months, or even more than six months, it must first fully charged and then use, fully charged after the best not to use immediately, need to stand for about ten minutes.

2, the battery won the charge, when installed, the battery installed in the electric bike to be strong, to prevent the battery when the battery by vibration damage. The battery in the handling, to prohibit throwing, rolling, weight.

3, often remove the battery cover on the dust, dirt, pay attention to keep the battery dry, clean, to prevent the battery discharge itself.

4, absolutely can not let the battery in a long time in the state of lack of electricity, and to develop a good habit of charging the battery every night. Long-term do not, should be full of electricity, place a cool dry place, and regular charge (usually 10 days).

5, electric bicycle just started, use the pedal (no foot can push the ground with the way the ground) to help start, uphill, with the pedal to help electric car uphill, so as not to discharge the current is too large and damage the battery.

6, riding, we should pay attention to not allow the battery over discharge, the battery discharge to the termination voltage, continue to discharge called over discharge. Over discharge easily lead to serious battery loss, thus greatly shortening its service life. So the battery should be used to avoid the depth of the discharge, so shallow ground charge, the general situation should be: the battery to discharge the depth of 50% when the best charge of a power.

Electric bicycles are generally equipped with undervoltage protection, when the battery power monitor only one indicator light, you should turn off the power, the use of foot, and try to charge the battery as soon as possible, so as not to overcharge the battery.

Battery discharge to the termination voltage when the internal resistance is large, the electrolyte concentration is very thin, especially the plate hole and the surface is almost neutral, over discharge when the resistance has a tendency to heat, volume expansion, discharge current is large, obviously fever And even the emergence of heat distortion, when the concentration of lead sulfate is particularly large, the possibility of survival of the short circuit of the increase, Moreover, when the lead sulfate will crystallize into larger particles, namely the formation of irreversible sulfation, will further increase the internal resistance, charge recovery Ability is poor, or even impossible to repair.

Batteries should be used to prevent overdischarge, take "undervoltage protection" is a very effective measure. In addition, because the electric car "undervoltage protection" is controlled by the controller, but the controller other than other devices such as voltmeter, indicator lights and other power appliances are directly powered by the battery, the power supply is generally uncontrolled Device control, electric car lock switch once closed to start electricity. Although the current is small, but if the long discharge 1-2 weeks will appear over discharge. Therefore, not a long time to unlock, when not in need to immediately turn off.

7, to avoid overcharge, when the charger is full to stop charging, not a charge on the night or even a few days. Overcharge will cause the plate active material hardening off, and produce dehydration and battery deformation. Batteries in the high temperature season to run, there are mainly overcharge problems. Therefore, the summer should try to reduce the battery temperature, to ensure good heat, to prevent exposure after the sun exposure, and should be away from heat.

To avoid overcharging, in addition to select the charger parameters to match the battery well, to fully understand the battery in the hot season of the operation, as well as the entire life of the changes during the period. Do not use the battery in the overheating environment, especially when charging should be away from heat. After the battery heat to take cooling measures, until the battery temperature to return to normal when the charge. The installation location of the battery should be as good as possible to ensure good heat, and found that overheating should stop charging, check the charger and battery. When the battery discharge depth is too shallow or the ambient temperature is high, the charging time should be shortened.

8, to avoid long-term loss of power, long-term loss will make the plate vulcanization. In the case of low temperature, the main charge charging capacity is poor, lack of charge caused by battery loss of power. Low temperature should be taken when the anti-freeze measures, especially when charging should be placed in a warm environment, is conducive to ensuring adequate power to prevent the generation of irreversible sulfate, to extend the battery life.

9, to prevent short circuit, in the installation or use should be particularly careful, the tools should be used to take insulation measures, the connection should be the first battery outside the electrical appliances connected with the check without a short circuit, and finally connected to the battery, wiring specifications should be good insulation, To prevent overlapping pressure generated rupture. Prohibit the use of battery short circuit method to detect the battery charge situation to prevent the explosion caused by casualties

When the battery in the short-circuit state, the short-circuit current up to hundreds of amps. Short-circuit contact more prison, the greater the short-circuit current, so all connected parts will produce a lot of heat, heat in the weak part of the larger, will connect the fuse, resulting in short circuit phenomenon. The battery may produce a local explosive gas or charge when the collection of explosive gas, when the fuse at the connection fuse, will cause the battery explosion; if the battery short circuit time is short or the current is not particularly large, may not cause the connection at the fuse Phenomenon, but the short circuit will still have overheating, will damage the connection around the adhesive, leaving the leakage and other hidden dangers. Therefore, the battery must not have a short circuit, in the installation or use should be particularly careful, the tools should be taken to take insulation measures, the connection should be connected to the electrical appliances other than the battery, the inspection without a short circuit, and finally connected to the battery, wiring specifications Should be well insulated, to prevent overlapping pressure generated rupture.

10, to avoid long battery current discharge, will greatly damage the internal structure of the battery. It is recommended that the owner can not start more than 5 seconds each time. Need two consecutive start, the middle of the interval to 10-15 seconds.

11, to prevent exposure in the sun, sun exposure will increase the battery temperature, the battery activity of the active substance increased, affecting the battery life.

12, after the discharge of the battery should be timely replenishment, shall not shelve more than 12 hours.
