A Robust Charge/Discharge Monitor for Lead Acid Batteries

Lead acid batteries are widely used in many industrial areas. Electric vehicles such as fork lift trucks, golf carts, wheelchairs, floor scrubbers, electric scooters are using lead acid batteries because of its low cost. However, due to improper charging, the batteries cannot be used as long as their theoretical life time. Huge money is spent on this premature failure, and a large forklift battery might cost $7,000. The manufacturer and customer also may have to cope with warranty issues. One problem is that many users omit a conditioning charge which should be performed after several bulk charging cycles. When the batteries are discharging, lead sulfate deposits will accumulate on the electrode, which is a common reason for battery failure, and this conditioning charge can help to reduce this problem. One reason conditioning charging is not performed properly is that the battery’s charging/discharging history is not recorded accurately. Therefore, the UT Power Electronics Lab has designed a low cost charge/discharge monitor to solve the problem.
