Interface is obstructed, plays safeguard protection effect.When charging inlet is connected with battery, battery positive voltage is connected on Vout1, negative pole
It is connected on Vout2.Then operational amplifier A output high level, Q1 conductings, relay K1 are connected.Operational amplifier B exports low electricity
Flat, Q2 cut-offs, relay K2 disconnects.As shown in Fig. 2 then charger positive pole exports and gives charging inlet Vout1, negative pole is exported to filling
Electrical interface Vout2, into charged state.Similarly, when charging inlet is connected with battery, battery terminal negative is connected on Vout1,
Positive pole is connected on Vout2.Then operational amplifier A output low level, Q1 cut-offs, relay K1 disconnect.Operational amplifier B outputs are high
Level, Q1 conductings, relay K2 are connected.As shown in figure 3, then charger positive pole exports and gives charging inlet Vout1, negative pole export to
Charging inlet Vout2, into charged state.
