In recent years, with the rapid development of the tourism industry, there are more and more tourist attractions for electric tourist vehicles. However, in the frequent use of electric sightseeing vehicles, we should still better maintain the battery of the vehicles. .
1, sightseeing car battery parallel mixing
When some drivers started the generator, because the battery power of the electric sightseeing car was not enough, it was used in parallel with another battery that had already had sufficient power, but it was actually sufficient after the two batteries were installed. The battery with a large amount of charge will be charged with a large charge current to a battery with insufficient battery power. This use condition is very likely to cause the active material of the plate to fall off, which will greatly affect the service life of the battery. In the case where the battery's power is already insufficient, the correct way is to remove the battery and replace it with a sufficient battery to start the engine.
2, tourist car battery series mix
Some drivers may use the old battery and the new battery in series when using a sightseeing car. The battery may be used in series with the new battery. Everybody may not know that this method of use will rapidly shorten the battery. The service life. Because there are many chemical reaction materials in the new battery, the terminal voltage is relatively high. The internal resistance of the new battery is only 0.015-0.018Ω, but the end voltage of the old battery is relatively low, and the voltage of the 12V battery can be low. Resistance can reach 0.085Ω or more. If the battery is to be used in series with a new battery, the charging voltage at both ends of the old battery will be higher than the charging voltage at both ends of the new battery in the case of charging. The end result may result in sightseeing. The new battery charge of the car is insufficient, and the charge capacity of the old battery will increase, resulting in excessive discharge of the old battery, resulting in the reverse polarity of the old battery. Therefore, old batteries and new batteries cannot be used in series. (Text / Sun Ni)
