When it comes to lithium batteries, we all know that some friends ask what kind of battery is commonly used for electric vehicle batteries. In addition, some people want to ask whether electric vehicle batteries are better than lithium batteries or lead-acid batteries. What's going on? In fact,...

Many electric vehicle users have this question, which is how much electricity does it take to fully charge an electric vehicle? What is the power consumption per kilometer? As a mechanic, today I will give you a detailed answer to this question.At present, most electric vehicles are 48V, 60V, and 72...

Introduction to wiring circuits and methods for lithium battery protection boards. As a safety protection device for lithium-ion batteries, the protection board should not only work reliably within the normal operating current range of the equipment, but also act quickly in case of accidental short...

Pulse charger is a type of dynamic charging that changes the charging current and voltage with the capacity and internal resistance of the battery itself. It achieves a balance between charging and discharging under this dynamic condition, and can also remove sulfates that appear in the battery afte...

Researchers from the Chemistry Department of the US Naval Research Laboratory (NRL) have developed a new type of battery - rechargeable zinc batteries, which they claim are safer than lithium batteries. And its research institute has been banned on naval vessels and other special platforms due to th...

Both 3.7V and 4.2V are the same for lithium-ion batteries. It's just that the manufacturer's labeling is different. 3.7V refers to the platform voltage (i.e. typical voltage) at which the battery is discharged during use, while 4.2V refers to the voltage at full charge. The common rechargeab...

Working principle of dry batteriesThe main working principle of dry batteries is to achieve redox reactions in a closed circuit! Similar to a primary battery, it converts chemical energy into electrical energy. A common dry battery is a zinc manganese battery, with a positive carbon rod in the middl...

Recently, a Miss Cai purchased a luxury brand model and did not expect the battery to become unusable after using the car for a year and a half. So Miss Cai went to the 4S store and after inspection, the other party informed her that it was because the natural lifespan of the battery had ended, and...

Power type lithium batteries, also known as power lithium batteries, are mainly characterized by supporting high rate charging and discharging, which can reach over 10C. The main consideration is the specific function (W/kg).The main characteristic of a capacity type is its specific energy (Wh/kg).F...

Analysis of 18650 lithium battery parameters and operating temperature range. As a very important invention in history, the emergence of batteries has indeed solved many problems and greatly improved various life efficiency. The emergence of lithium batteries has further deepened people's unders...
