In July, production and sales fell to single digits, exposing the dilemma of commercialization of fuel cell vehicles. However, compared to the numbers, it is more important to recognize the industry positioning of fuel cell vehicles. According to recent data released by the...

The Transportation in the United States Safety Administration (TSA) has made the following proposals for the safe use of lithium-ion batteries: 1. Use original charger: Charging time is a high incidence period for lithium-ion battery explosions. An original charger ensures b...

Battery explosion decomposition - burying missiles in electrolyte According to renowned American science writer Marshall&midt; According to Brian's analysis in the series of articles on lithium-ion batteries, the vast majority of lithium-ion battery explosions are ca...

The domestic lithium-ion battery recycling industry is just starting, with a corresponding recycling rate of only 2%, which is difficult to meet environmental standards. It is generally believed that Lithium iron phosphate ion batteries are more suitable for cascade utilization, while ternary lithiu...

▲ Overcharging If a lithium-ion battery is overcharged, excess electrical energy will be converted into thermal energy, resulting in damage to the battery body due to an increase in temperature. This problem often occurs on chargers or electronic products that do not have o...

▲ Needling, short circuit, squeezing When a lithium-ion battery experiences a short circuit, puncture, or compression, it can cause the internal diaphragm to rupture, causing a sudden explosive increase in temperature, ultimately leading to an explosion. Especially for lith...

Balance does not work: Many people believe that batteries work in the middle and later stages of using balance. The actual battery pack used in the middle and later stages has poor capacity due to different battery capacity losses, and the balance protection board cannot compensate for the bat...

The commonly used equalizing charging technologies for the equalization principle of lithium ion battery protection board include constant shunt resistance equalizing charging, on/off shunt resistance equalizing charging, average battery voltage equalizing charging, Switched capacitor equalizi...

Development prospects of lithium-ion batteries The constantly rising prices may cause problems for lithium-ion batteries, as cost is an important factor hindering their expansion into renewable energy applications. However, lithium is currently not a significant factor in th...

When the battery voltage exceeds 4.2v or the total voltage exceeds 16.8v during the charging process, it is judged that the battery is in an overcharged state. At this point, the protection execution circuit cuts off the charging protection switch. In the state of overcharging release, the voltage o...
