An electronic battery tester and method includes generating battery test data from an electronic battery test. The battery test data is transmitted over a wireless communication medium. In another aspect, a method and apparatus is provided for receiving battery test data from a wireless communication medium. Also, a diagnostic battery charger, which is capable of transmitting battery condition information to an external receiver, is provided.

A method and apparatus for simulating a battery tester with a fixed resistance load, such as a widely used Japanese load tester that rates the strength of Japanese batteries that are categorized under the Japanese Industrial Standard (JIS), are provided. This invention simulates such a device without invoking large current loads, yields familiar results, utilizes an existing database and provides more conclusive testing. The method includes measuring an open circuit voltage (OCV), temperature and a dynamic parameter of the battery. A load voltage of the battery is estimated as a function of the measured battery dynamic parameter, the OCV, the load resistance value of the load tester and the battery temperature. A bounceback voltage (BBV) of the battery is then predicted. The BBV, the load voltage and the battery temperature are utilized to rate the strength of the battery.

A cable for use with an electronic battery tester includes first and second electrical connections configured to couple to terminals of a battery. A memory is configured to store digital data. Electrical terminals are configured to couple the cable to the electronic battery tester.

A battery tester that is capable of calculating its own reference values is provided. The battery tester includes test circuitry that is configured to obtain dynamic parameter values for batteries, and to compute at least one reference value based on the dynamic parameter values.

A method and apparatus for coupling a battery charger and / or a battery tester to a battery is provided. A clamp can be selectively removed from a cable. This allows replacement of the clamp as desired as well as fixedly or removably coupling the cable to the battery tester or charger.

A bounceback voltage (BBV) of the battery is also predicted. The BBV, load voltage and battery temperature are utilized to rate the strength of the battery. Also, to improve the accuracy of test results for a substantially discharged battery, one embodiment projects the results of recharging discharged batteries without actually doing so.

An electronic battery tester for testing a storage battery. The tester includes a first connector configured to electrically couple to a first terminal of the battery via a first battery post adapter and a second connector configured to electrically couple to a second terminal of the battery via a second battery post adapter. The tester also includes an input configured to receive a battery-post-adapter-connection indicator. Test circuitry, which is coupled to the input, upon receipt of the battery-post-adapter-connection indicator, determines whether or not the first battery post adapter and the second battery post adapter are faulty.

Testing or diagnostics are performed on an electric vehicle. The vehicle is operated and current flow through a system of the vehicle is monitored. A voltage related to the system is also monitored. Diagnostics are provided based upon the monitored voltage and the monitored current.

Battery maintenance equipment is provided for use in maintaining storage batteries. The battery maintenance equipment includes battery maintenance circuitry. A redemption code output is provided and configured to provide an output having a redeemable value in response to the battery maintenance circuitry. A method includes outputting a redemption code in response to usage of battery maintenance equipment.
