Abstract

The thermal protection circuit, for a traction battery, has a thermostat in thermal contact with the battery's electrodes and with its contact (4) in series across the battery with a relay's excitation coil. When a given max. temp. is reached this contact closes (or opens) and excites (or de-excites) the relay. the relay contacts operate the modify the charging or discharging conditions of the battery. The electromagnetic relay may be replaced by a transistor circuit and the thermostat may comprise several thermostats each in contact with one electrode.
