Based on pulse fast charge of the lead acid battery, this paper designed a kind of intelligent battery charger, including mainly a minimum system of 16 bit MCU as intelligent center, the constant resistance discharge unit to complete SOC prediction and duty cycle of the pulse charging waveform, the voltage-current-temperature measurement unit, pulse charging control unit. The duty cycle of this charger agreed with SOC of the battery, then using short floating charge in the later stage, thus greatly optimizing the pulse charging mode. Finally, compared with the conventional constant voltage and constant current charging, the charger greatly reduced the charging time.

Abstract Soil lead levels were determined on and around a former battery manufacturing site. Lead concentrations ranging from 120 ppm to 5.1’ were found. The highest concentrations were found close to the factory site. When it was possible to obtain samples over a continuous depth range, it was found that lead concentration decreased with depth and that it increased above underground foundations.
