Since the implementation of the new national standard for electric vehicles, lithium batteries, as a new type of energy storage battery, are gradually replacing traditional lead-acid batteries. Compared with lead-acid batteries, lithium batteries have many advantages, such as high energy density, small size, light weight, environmental friendliness, and no memory effect.
With the popularity of lithium batteries, their daily maintenance has become a major concern for countless consumers.
What aspects should be considered for the routine maintenance of lithium batteries?
• The charger must be compatible.
The charger must be fully compatible with the lithium battery. Never use a lead-acid battery charger directly, as excessive current from the charger will damage the lithium battery's protection system, causing a short circuit and potentially leading to a safety hazard. Insufficient charger voltage will result in low charging efficiency and excessive charging time.
Master the correct charging method
First connect the charger to the battery pack, then connect the charger's power plug to a 220V AC power source. This connection sequence avoids electrical sparks when plugging and unplugging the charger. The charger will display a red indicator light when the power is on.
Remember to charge and release only shallowly.
The basic principle to follow when using lithium batteries is shallow charging and discharging. This means charging them promptly, rather than waiting until they are almost depleted, to ensure the battery voltage remains stable. Deep discharging (more than 90% capacity) before recharging can easily damage the battery.
When lithium-ion electric vehicles are not in use, the power should be turned off promptly, or the battery pack should be removed from the battery holder and stored separately. This is because the motor and controller still consume power even when not in use. Especially when parking for extended periods, it is best to perform a charge-discharge cycle, similar to an "activation," once a month to prevent passivation of the battery electrodes, which can damage the electrode structure and ultimately affect battery life.
Avoid contact with metal contacts to prevent metal objects from touching the positive and negative terminals of the battery, causing a short circuit and damaging the battery; at the same time, do not knock, prick, step on, modify, or expose the battery to sunlight to avoid danger.
