Method and apparatus for automotive and other battery testing
First Claim
1. A method of testing applicable to the routine testing of batteries for automotive vehicles and like batteries, the method comprising:
- a) providing a battery to be tested;
b) providing a test electrical load for connection to said battery;
c) providing a control circuit adapted to connect said load to said battery for an interval of less than one second; and
d) providing analysis means adapted to analyse the voltage profile or related aspects of said battery'"'"'s reaction to said load over said interval;
characterised by e) causing said load to cause said battery, at least for batteries in good condition, to deliver a transient macro-current which is comparable to currents arising in use of the battery;
f) causing said control circuit to connect said load to said battery for a transient time interval lying in the range of up to 100 milliseconds; and
g) providing said control circuit as part of a handset apparatus adapted to be operated and connected to said battery in the manner of a testing handset, and said transient macro-current generating an amount of heat in relation to said handset which can be accommodated by apparatus of the handset kind.

Abstract
A method of testing applicable to the routine testing of batteries for automotive vehicles and like batteries is described. The method comprises: providing a battery to be tested; providing a test electrical load for connection to the battery; providing a control circuit to connect the load to the battery for an interval of less than one second; and providing analysis means to analyze the battery'"'"'s reaction to said load. The invention is characterized by causing the load to cause the battery to deliver a macro-current which is comparable to currents arising in use of the battery; causing said control circuit to connect the load to the battery for a transient time interval lying in the range of up to 100 milliseconds; and providing the control circuit as part of handset apparatus adapted to be operated and connected to the battery in the manner of a testing handset, and the transient macro-current generating an amount of heat in relation to the handset which can be accommodated by apparatus of the handset kind.
