Description

Starter control device suitable for different power supply characteristics Technical Field The utility model relates to a starter control technology, in particular to a starter control device suitable for different power supply characteristics. Background The matched power supplies of the existing engine are two types of lead-acid batteries and lithium batteries. The prior engine is basically provided with a lead-acid battery as a matched power supply, and the starter is designed according to the characteristics of the lead-acid battery. However, as the demand for vehicles increases, the application advantages of lithium batteries become more and more apparent. For example, in the long-distance transportation and loading process, the requirements on the comfort and practicality functions of the vehicle are higher and higher for heavy truck users, so that a plurality of whole vehicle users select to use lithium batteries when matching power supplies. There is a need for a starter that is configured with both lead acid and lithium batteries. Compared with a lead-acid battery, the lithium battery has low internal resistance (usually 0.5-2mΩ, and the lead-acid battery is 5-20mΩ), the instant discharge current can reach 2-3 times of that of lead-acid, so that the overheating of a starter coil and the abrasion of an electric brush are aggravated, the full-charge voltage of the lithium battery is 2-3V higher than that of the lead-acid battery, and the problems of easiness in ablation of an electromagnetic switch contact of the starter and the like are caused.
