Problems solved by technology
[0006] At present, in view of the air-conditioning / heating function affecting the battery life / continuation of the equipment, the general solution is to improve the accuracy of the energy storage battery and load physical parameter model and the accuracy of the software algorithm, and implement as accurate feedback as possible of the remaining power and battery life information. , at the same time, in order to reduce the user's battery life anxiety, the unprincipled increase in the installed capacity of the device will virtually increase the load on the device during the season when the air conditioner / heater function is not needed, and will also increase the silence of the energy storage battery to a certain extent. cost

The invention discloses a system meeting flexible energy supplement and emergency power supply of pure electric equipment. The system comprises a main battery, an auxiliary battery, a first contactor, a second contactor and a third contactor, the main battery is electrically connected with a power system through the first contactor; the auxiliary battery is electrically connected with the temperature adjusting system through the second contactor; the output ends of the first contactor and the second contactor are electrically connected through the third contactor. The invention provides a system and a method for meeting flexible energy complementation and emergency power supply of pure electric equipment. A main battery energy storage unit required by a temperature adjusting system and a power system of pure electric equipment is separated, so that the use temperature adjusting function of the equipment in summer and winter is met, wherein the auxiliary battery energy storage unit can be independently installed or replaced to flexibly achieve electricity utilization, the influence on the cruising ability of the device when the function of the temperature adjusting system is used is eliminated, and therefore, the anxiety of a device user due to endurance is eliminated.
Description
technical field [0001] The invention relates to the technical field of equipment power supply, in particular to a system and method for flexible energy replenishment and emergency power supply of pure electric equipment. Background technique [0002] With the breakthrough progress of lithium-ion battery technology, the application of pure electric technology in the fields of automobiles, construction machinery and special equipment has become a mainstream technology route for a wide audience. [0003] However, for existing equipment powered by a single energy storage unit, in high temperature / alpine environments, the performance of the power battery is attenuated and the use of air conditioners / heaters accelerates the power consumption of the energy storage unit, which in turn accelerates the attenuation of the equipment’s battery life. This kind of impact has a degree that non-professional users cannot predict due to the difference in temperature of the external environment...
