Embodiment
As shown in Figure 1, the utility model one embodiment MCU(micro-control unit) connect code translator, decoder output is measured light coupling relay with the voltage gating and is connected respectively with temperature gating measurement light coupling relay.After gating single battery voltage, measure battery terminal voltage by differential mode amplifier isolation output.After monomer battery voltage has detected, MCU stores its terminal voltage, and as the total voltage that contains the thermistor bleeder circuit, cell voltage was patrolled and examined gating circuit and was remained closed this moment, and the temperature survey light coupling relay is closed, and thermistor becomes bleeder circuit with differential mode output terminal resistor group, sample by A/D and record partial pressure value, the contrast total voltage, MCU calculates the thermistor resistance, tables look-up and obtains cell temperature this moment.
Micro-control unit can adopt DSP, ARM, single-chip microcomputer etc.
With Fig. 2 example, each code translator is controlled 8 single batteries, when code translator is enabled, if the value of K2K1K0 is 001 o'clock, code translator output Y1 is low level, optocoupler OP3, OP4 conducting, battery B2 two ends are strobed, and are connected to the differential mode voltage circuit that integrated transporting discharging forms.This moment, temperature detecting module was closed, and Kt is high level, therefore the voltage that enters sampling module by R0 is battery terminal voltage.After sampling was completed, MCU preserved the battery terminal voltage value, then opens temperature detecting module, and Kt becomes low level, the OPt2 conducting that be connected with Y1 this moment, and R0 and Rt2 form bleeder circuit, and the voltage that enter the sampling module circuit this moment is the partial pressure value of thermistor Rt2.Because the time interval is very short, think that this moment battery terminal voltage is constant, can try to achieve the resistance of thermistor, battery temperature this moment of tabling look-up namely as can be known.
