The fixes will include:
+Strengthening an existing portion of the Volt’s vehicle safety structure to further protect the battery pack in a severe side collision.
+Adding a sensor in the reservoir of the battery coolant system to monitor coolant levels (pictured below).
+Adding a tamper-resistant bracket to the top of the battery coolant reservoir to help prevent potential coolant overfill.

This is an excellent animation of how the new safety features will be added to the Volt’s battery:

The debate will likely rage for years about the optimal battery technology, but Ann Thryft at DesignNews says improvements are coming sooner than later:

And if you had the chance, how would you redesign the battery for better safety? Some of our readers have ideas:
