In theory, electric vehicle chargers cannot be universal, which is the same as the principle of mobile phone chargers. It mainly depends on whether the voltage and current are consistent. Generally, chargers of the same brand are more likely to be universal, but when used, it is still necessary to check whether the voltage and current match. Many users think that as long as they can plug in and turn on the light, they can be universal. In fact, this can easily damage the battery.
However, today's electric vehicle charger products are also increasingly user-friendly in terms of functional design. In terms of universal issues, high-end technology electric vehicle chargers are relatively good. Charging is possible as long as the voltage and current match between the electric vehicle charger and the battery.
In addition, high-end electric vehicle chargers and Haoyi electric vehicle chargers have been designed with new protection functions, such as constant current charging and constant voltage charging. The main factors causing damage to the battery due to mismatched electric vehicle chargers are current and voltage issues.

Precautions for electric vehicle chargers:
1、 Constant current charging
The main characteristic of constant current charging for electric vehicle chargers is that this charging method has great adaptability, and the charging current can be freely selected and adjusted. Therefore, it is possible to charge batteries in various situations and states (such as initial charging of new batteries, supplementary charging of used batteries, and sulfur removal charging).
It is particularly suitable for charging with low current for long periods of time, charging battery packs connected in series with most batteries, and is beneficial for charging batteries with slower capacity recovery.
However, due to the low charging current at the beginning of the charging method and the high charging current at the later stage, the entire charging process takes a long time, releases a lot of gas, has a large impact on the electrode plate, high energy consumption, and low efficiency (not exceeding 65%), and the entire charging process must be supervised by a dedicated person. Therefore, it should only be used for initial charging of the battery and for long-term low current desulfurization charging.
2、 Constant voltage charging
The main characteristics of electric vehicle chargers are: the initial charging current is relatively large, and the battery electromotive force and relative density of electrolyte increase rapidly. As the charging continues, the charging current gradually decreases, and only a small amount of current passes through during the final charging period; Short charging time and low energy consumption. Generally, after 4-5 hours of charging, the battery can obtain 90% to 95% of its own capacity.
If the charging voltage is properly selected, the entire charging process can be completed in 8 hours, and the entire charging process does not require human care, so it is widely used for supplementary charging.
