Circuit protection scheme for children twisting cars
Based on the latest UL2272 balanced car circuit system certification standard, FAE engineers of Shuokai Electronics designed two circuit protection solutions for children's twisted and twisted vehicles, namely battery interface protection scheme and motor interface protection scheme. Battery interface protection scheme: Use a PTC and a TVS tube on the battery output port. Self-resetting fuses can prevent over-current in the downstream circuit from damaging the battery pack and prevent accidental charging due to excessive charging current during charging. At the same time, the fuse can also function as over-temperature protection. As long as the design is reasonable, the temperature can be too high. The current is controlled in a timely manner to prevent the occurrence of a fire accident; and the transient suppressor diode therein can prevent surges and static electricity from damaging the battery pack. Motor Interface Protection Program: A transient suppression diode is connected to the motor port and the motor drive circuit. The transient suppression diode in this protection scheme can not only suppress the surge, but also effectively absorb the static electricity generated during the operation of the motor. Children's twist car circuit protection program can refer to the automotive electronics circuit protection program, and according to the actual circuit conditions for more effective rectification and circuit protection device selection. Circuit Protection Experts SK Electronics has professional EMC laboratories and experienced FAE electronic engineers who can provide UL certification test for children's twisting vehicles and help more merchants pass UL fire test of children's twisting vehicles.
