Multifunctional battery health state detection device and system thereof

A multifunctional battery health state detection device (100) configured to identify a battery health state of a vehicle battery which is classified into a plurality of rankings, comprising:

• a housing defining an accommodating space therein;
• two ignition clamps (102, 104) connected to the housing and configured for connecting to the vehicle battery having a positive polarity and a negative polarity;
• a microcontroller (106) received in the housing;
• a sampling circuit (108) connected between the two ignition clamps (102, 104) and the microcontroller (106), the sampling circuit being configured for sampling a voltage signal of the vehicle battery when the two ignition clamp (102, 104) are connected to the vehicle battery and sending the sampled voltage signal to the microcontroller (106);
• and
• an indicator unit (110), connected to the microcontroller (106), comprising a plurality of indicators configured to display a ranking of the battery health state of the vehicle battery, wherein the plurality of indicators are mounted on the housing;
• wherein the microcontroller (106) is configured to obtain the sampled voltage signal of the vehicle battery, detect which ranking of the battery health state is based on the sampled voltage signal, and control the indicator unit (110) to display the battery health state according to the ranking of the battery health state, and wherein the plurality of indicators are corresponding to the plurality of rankings respectively;
• and
• wherein the multifunctional battery health state detection device is further configured to connect to a portable power supply, and wherein the microcontroller (106) is configured to switch on a circuit between the portable power supply and the vehicle battery to boost the vehicle battery through the two ignition clamps (102, 104) in response to detecting the battery health state being one of two lowest rankings among the plurality of rankings.
