Safety & Standards

Safety is built into every Jolt charger at the hardware level — the charge controller enforces these interlocks independently of the network or app, and a fault always takes the charger to a safe state.

Enclosure & environment

Ingress protection	IP65 (dust-tight, water-jet resistant)
Impact protection	IK08 (IEC 62262)
Operating temperature	−35 °C to +55 °C
Storage temperature	−40 °C to +80 °C
Cooling	Air cooled
Mounting	Wall or pole

Personal-safety protection

• Type B RCD — residual-current protection detecting 30 mA AC and 6 mA DC leakage.
• Continuous earth (PE) monitoring — the charger checks protective-earth integrity before and during a session.
• CP diode detection — verifies a valid vehicle control-pilot circuit before energising.
• Emergency stop — optional hardware e-stop.

Electrical protection

• Over/under-voltage — protection above 275 V AC with automatic recovery.
• Over-current — software-controlled limiting in the charger; an external MCB is fitted during installation.
• Surge protection — differential mode ±3 kV, common mode ±6 kV.
• ESD — air discharge ±8 kV, contact discharge ±4 kV.
• EFT — ±4 kV.

Temperature & voltage derating

Rather than cutting a charge off abruptly, a Jolt charger derates — it lowers the delivered current to stay within safe limits, and only pauses charging if it has to.

• Voltage derating. The charger enforces a maximum apparent-power (VA) limit to protect its internal electronics. Because power = voltage × current, the current it allows scales with the supply voltage: as voltage rises, the charger trims current to keep power under that limit.
• Temperature derating. As the charger’s internal temperature climbs toward its limit, it progressively reduces the maximum current to shed heat. If temperature keeps rising past the safe threshold, it pauses the session (signalled as a Temperature fault — see LED status) and resumes automatically once the unit cools.

Example. A 7.4 kW unit is delivering 32 A at 230 V (≈ 7.4 kVA):

• If the site voltage rises to 250 V, holding the same power budget means the charger reduces current to about 30 A (7.4 kVA ÷ 250 V) — voltage derating.
• If, on a hot afternoon, the internal temperature crosses its threshold, the charger steps current down — for example 32 A → 24 A → 16 A — to keep cooling; if it still climbs, it pauses charging until the unit cools, then ramps back up.

Metering

Jolt Business includes a Class 1 certified energy meter for billing-grade measurands. Home and HomePlus report basic measurands only and are not certified for paid billing — see The Jolt family.

Standards & compliance

• IEC 61851-1 and EN 61851-21-2 — EV conductive charging system & EMC.
• IEC 62196 (Type 2) — connector.
• IEC 60664-1 — insulation coordination (dielectric withstand tested at 1615 V AC).
• ARAI IS 17017 — Indian EV supply-equipment standard.
• CE marked.
