Description

technical field [0001] The invention relates to an emergency starting power supply, in particular to an emergency starting power supply for lithium-ion vehicles. Background technique [0002] At present, for the emergency starting of various vehicles, most of them are completed by lead-acid batteries on rescue vehicles or special power supply vehicles. This battery is widely used and cheap. But the biggest disadvantage is that it is large in size, heavy in weight, poor in high and low temperature resistance, and has a short cycle life. (The minimum weight of a group of 24-volt lead-acid batteries is about 55 kg. When the battery temperature is 26.7°C, the starting energy is 100%; at 0°C, the starting ability is 65%; at -17.8°C, the starting ability is only 40%; The cycle life is generally 300 times) In the cold zone, the vehicle is turned off due to battery failure or parked outside the garage for a long time, coupled with insufficient battery capacity, the engine cannot b...
