The hydrological intelligent current measuring boat is not the kind of equipment that needs to work in extreme environments. In fact, most batteries on the market are suitable. However, from various aspects, lithium-ion batteries are undoubtedly the most suitable batteries for hydrological intelligent current measuring ships, mainly because of the following advantages of lithium-ion batteries.
1. energy is relatively high. It has high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries;
2. Long service life, the service life can reach more than 6 years, the battery with lithium ferrous phosphate as the positive electrode is charged and discharged at 1C (100% DOD), and there is a record of 10,000 times of use;
3. High rated voltage (single operating voltage is 3.7V or 3.2V), which is approximately equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries, which is convenient to form a battery power pack; lithium-ion batteries can be adjusted by a new type of lithium-ion batteries. The voltage is adjusted to 3.0V, which is suitable for the use of small electrical appliances.
4. With high power tolerance, the lithium iron phosphate lithium-ion battery for electric vehicles can reach 15-30C charge and discharge capacity, which is convenient for high-intensity startup acceleration;
5. The self-discharge rate is very low, which is one of the most prominent advantages of the battery, generally less than 1%/month, less than 1/20 of the nickel-metal hydride battery;
6. Light weight, the weight is about 1/6-1/5 of lead-acid products under the same volume;
7. High and low temperature adaptability, can be used in the environment of -20℃–60℃, and can be used in the environment of -45℃ after technical treatment;
8. Green and environmentally friendly, no matter whether it is produced, used or scrapped, it does not contain or appear any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium.
9. Production basically does not consume water, which is very beneficial to my country, which is short of water.
