Everything you need to know about electric car chargers is here

For the need to charge products, especially electric car battery this large capacity products, we are very cautious, in the choice and use of electric car charger also have some questions, next to tell you about the charger that thing.

Can the chargers be mixed?

Electric car chargers should not be mixed. For example, lead acid battery 48V and 60V charger, 48V charger's maximum voltage is about 59V; The maximum voltage of the 60V charger is about 74V. If you use a 48V charger to charge a 60V battery, the charger won't break, but it won't charge. After a short time, it is full because the charger judges that it is fully charged by detecting the feedback of battery voltage. In fact, it is virtual. On the other hand, if you use a 60V charger to charge a 48V battery, it will overcharge. First, it will lead to battery water loss, water loss will make the battery capacity slightly larger in the short term, but the life will be shortened; Second, it increases the risk of battery expansion. Overcharging does not necessarily lead to battery expansion, but will basically lead to battery temperature rise. If overcharging continues, the battery is likely to expand.

Even lead-acid and lithium batteries of the same specification cannot be mixed with chargers. The materials are different, the voltage platform is not the same, and lithium battery has higher safety requirements, so the design of charging parameters and functions are not the same.

Charger overheating is how to produce, what is the harm?

The working principle of the charger is to convert the alternating current into the direct current that can charge the battery. Its core essence is a conversion power supply, so it is inevitable to generate a certain amount of heat. The key is how to effectively dissipate the heat in time to prevent the internal heat focus and cause substantial harm. For the charger using fan heat dissipation, keeping good air duct and choosing reliable high-quality fan are the key to ensure charging safety.

If the charger overheats for a long time, the internal temperature is high, the components and wires are easy to aging, and the fan lubrication fails, the temperature will further increase, forming a vicious cycle, light damage to the charger, damage to the battery, serious fire.

What happens to water in the charger?

Charging in rain or humidity can cause water to fill the charger, which is a very dangerous thing. As a conversion power supply, its internal AC circuit and DC circuit, AC circuit part or the whole board water easily burn circuit board and control components, at the same time, electricity conduction in water medium, human body close to touch will bring irreparable damage; If the dc circuit is partially flooded or damp, the electronic components will fail. If the charger is still working but the voltage control circuit has failed, the drum battery will be charged. Therefore, when the charger water, should be immediately disconnected from the power supply.



Through the above explanation, it is not difficult to find that the charger overheating, water may cause accidents, and in real life charger heat and water is difficult to completely avoid, so it is very important to choose a safe and reliable charger. Luyuan intelligent charger, through two designs to solve the charger overheating and water problems. One is the use of double bearing micro fan design, increase ventilation, to achieve rapid heat dissipation, the fan can ensure 70,000 hours of trouble-free operation. Two is high foot, double sink design, four high charger foot, pad high charger, so that it is not easy to water; Even if the water is unfortunate, the dual sink can quickly drain the charger internal water. It can not only effectively drain water but also effectively prevent dust -- the dust filter screen is used to prevent dust from entering. In addition, ordinary chargers have the same length of charging lines at both ends, so users have to hang them on the handlebars when charging, while Luyuan smart chargers use different length lines, which can always be positioned when charging. Accordingly, luyuan intelligent charger realizes rain proof, dust proof and overheating proof, charging safely.
