For products that need to be charged, especially large-capacity products such as electric vehicle batteries, you will have some questions when choosing and using them. Next, let me tell you something about chargers.
Electric car charger can't be mixed. For example, 48V and 60V chargers of lead-acid batteries, the highest voltage of 48V charger is about 59V；; The highest voltage of 60V charger is about 74V. If a 48V charger is used to charge a 60V battery, the charger won't break, but it can't be charged. After a short time, it is indicated that the battery is fully charged, because the charger judges that it is currently fully charged by detecting the feedback of the battery voltage, which is actually a virtual power. On the contrary, if the 48v battery is charged with a 60v charger, it will be overcharged. First, it will cause the battery to lose water, which will make the battery capacity slightly larger in a short time, but the life will be shortened; The second is to increase the risk of battery expansion. Overcharging may not necessarily lead to battery expansion, but it will basically lead to battery temperature rise. If it continues to be overcharged, the battery is likely to expand.
Even lead-acid batteries and lithium batteries of the same specification can't mix chargers. The two materials are different, the voltage platform is different, and the lithium battery has higher safety requirements, so the designed charging parameters and functions are also different.
The working principle of the charger is to convert alternating current into direct current which can charge the battery. Its core essence is a conversion power supply, and 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 from focusing and causing substantial harm. For chargers using fans to dissipate heat, it is the key to ensure the charging safety to keep the air duct good and select reliable high-quality fans.
If the charger is overheated for a long time, the internal temperature is high, the components and wires are easy to age, and the lubrication of the fan fails, it will further aggravate the temperature rise, forming a vicious circle, causing damage to the charger, battery damage and even fire.
Charging in the rain or wet environment will cause the charger to enter water, which is a very dangerous thing. As a conversion power supply, it has an AC circuit and a DC circuit inside. The water in the AC circuit or the whole board easily burns the circuit board and control elements. At the same time, the electricity is conducted in the water medium, and the human body will bring irreparable damage if it touches. If the DC circuit is flooded or wet, the electronic components will fail. If the charger is still working, but the voltage control circuit has failed, the battery will be charged. Therefore, when water is found in the charger, the power supply should be disconnected immediately.
After the above explanation, it is not difficult to find that overheating and water intrusion of the charger may cause accidents. However, in real life, it is difficult to completely avoid the heat and water intrusion of the charger, so it is very important to choose a safe and reliable charger. Intelligent green charger, through two designs, solves the problems of overheating and water inflow of charger. First, the design of double-bearing mini-fan is used to increase ventilation and realize rapid heat dissipation. The fan can guarantee 70,000 hours of trouble-free operation. Second, the design of high footrest and double sinks, with four heightening chargers for footrest and padding the charger, make it difficult to accumulate water; Even if water enters unfortunately, the double water tank can quickly discharge the accumulated water inside the charger. Not only can it effectively drain water, but it can also effectively prevent dust-the dust screen used can prevent dust from entering. In addition, the charging wires at both ends of the ordinary charger have the same length, so users have to hang them on the handlebars when charging, while the Luyuan intelligent charger adopts unequal long and short wires, which can always be positioned and placed when charging. Accordingly, the intelligent charger of Luyuan realizes rain-proof, dust-proof and overheat-proof, and the charging is safe and worry-free.
